FYI, I built a Linux debug version, and it crashed in the same way as the Linux \
release version. It seems the only version that works for me is the Windows debug \
build.

I added "-mstackrealign" to all C/C++ compilations I could find, and it was a vast \
improvement! I made a Windows debug build of smokegen/smokeqt/assemblygen, and my \
project seemed to run fine!
I made a Windows release build of smokegen/smokeqt/assemblygen, and it got pretty \
far through the initialization before it crashed. Enclosed is what I could get out \
of gdb. It got all the way to the line "QObject.Connect(actionQuit, \
Qt.SIGNAL("triggered()"), ErrorList, Qt.SLOT("close()"));" in my uics-generated file, \
and then did this.
Under Linux, I made a release build of smokegen/smokeqt/assemblygen, but it crashed \
quickly after startup. Enclosed is all the debug output I could get out of it.
Any suggestions on either of these crashes would be appreciated.
Do you make release buiilds of smokegen/smokeqt/assemblygen very often?

"-mstackrealign" is the last of my local changes, the others I've had(like commented \
out DBus)you solved with your 9 patches. About the scripts, if "-mstackrealign" works \
on Linux you may just add it, otherwise you'd have to check the platform and add it \
on Windows only. About your project, you're right, a small sample would be enough. As \
soon as you have it I'll test it.

I don't mind cmake -- it's certainly an improvement over autogen. :-) Please make a \
list of all your local changes, and I'll work on patches to do them all properly.
I only put "-mstackrealign" into qyoto. I'll go back and put it into smokegen and \
smokeqt also.
I didn't miss the question about my project being open-source...it isn't. But I'll \
see if I can trim it down to something that reproduces the problem.

Yes, "-mstackrealign" is a local change of mine. It would've been better if I had \
added it to the scripts but build scripts are my least favourite part so I just \
mailed the list back then. However, for now I have found the need to use it only on \
Windows because on Linux my app seems to work OK in the places I needed the flags \
for. Anyway, about Windows, remember that you have to place the flags in all parts \
(smokegen, smokeqt and Qyoto) in all 4 places - C and C++ compiler, debug and \
release.
About the QAction crash, you could, of course, try compiling with "-mstackrealign" on \
Linux as well but I think your best shot would be to track the null pointer now that \
you've found it. I looked at your stack trace but I do not have other ideas. I can \
see you've missed my question about your project being open-sourced. If it is, I'd \
check how it behaves on my machine, both on Windows and Linux (Ubuntu 12.04).

Subject: Re: [Kde-bindings] Building latest qyoto under Windows and Linux
I'm glad to hear that you run Qyoto under Linux on a regular basis. I half-feared \
that Qyoto had only been tested under Windows for a significant amount of time.
I managed to #define DEBUG in assemblies/qyoto-qtcore/native/qyoto.cpp, and I added \
a printf() to x_QAction::x_8() so that I could see the construction of the QAction.
Nothing seems amiss; I printed the value of ((QObject \
*)x[1].s_class)->objectName().ascii() and it returned the name I had assigned to my \
QMainWindow subclass. But it dies in QMetaObject::cast(QObject*). mdb shows that \
it's trying to dereference a null pointer, but I don't know where -- I can't get any \
more information on it.
If I dike out the parent pointer, the QAction constructor doesn't crash. The \
succeeding ObjectName property set on the QAction also succeeds.
Here's a minor point I noted along the way: the file generated by uics, at the top of \
SetupUI(), does this:
if (ErrorList.ObjectName == "")
ErrorList.ObjectName = "ErrorList";
ErrorList.ObjectName is null, so the test fails and the ObjectName is never set.
Attached is the debug output I was able to generate. Maybe it's slightly more \
useful.
If you have any suggestions for what else I should be printf()ing, I'd appreciate it.
Re: your other letter, no, I haven't added "-mstackrealign" to my compiler flags. \
I'll have to dig through the cmake files to figure out where to put this. I take \
it this is a local change on your side? How many more local changes do you have? \
Perhaps they're why your code is working and the checked-in code isn't?

Subject: Re: [Kde-bindings] Building latest qyoto under Windows and Linux
No, I meant printf-debugging inside Qyoto, mostly the unmanaged parts (like \
qtcore-native).
About the Windows version: as far as I can see, the replacement of System.Action with \
Qyoto.Slot hasn't actually dropped the .NET 4 dependency, is that correct? Please \
tell me yes or no so that I know if I need to work some more on that.
There are apparently some things that the assemblygen Qyoto is doing wrong in \
comparison to the non-assemblygen one. I have no idea what they are as I've never \
worked on the non-assemblygen version. Arno, any thoughts on that?
Is your project, by any chance, at least partly open-sourced? If it is I'd take a \
look what could be wrong on Windows.
I've run my project on Linux a few times, the last time was actually last night. I \
know about a crash that does not happen on Windows (QItemSelectionModel.Select) but \
the creation of a QAction works fine. However, I have so much work with the porting \
and especially the occasional bugs that I'm basically following an "OS-by-OS" plan - \
that is, I'm going to complete the port on Windows, make sure everything works \
properly, and then move on to test on Linux and then on Mac OS X.

You mean printf() debugging inside of Qt itself? I'll have to look into how to \
build a debug version of Qt.
Re: the version numbers, it turns out that 4.8.3 is the version of KDE that I'm \
running, of which smokegen/smokeqt/qyoto is a part. My version of Qt is 4.8.1-5.
Keep in mind that the same project (without the recent changes for the new API) has \
been running under the non-assemblygen version of Qyoto, under Windows and Linux, for \
months. The only problem I've had is that, every once in a while, bringing up the \
open-file dialog crashes the program completely. Other than that, it's been running \
fine.
I got further with the MS Windows version. I had to change my project to use .NET \
4.0 there too, and then it stopped hanging on startup. I managed to create my \
QMainWindow subclass and see it on the screen, but then it died inside of \
QApplication.Exec(). Enclosed is all I could get out of gdb.
When was the last time anyone (besides me) tried to run the assemblygen variant of \
Qyoto under Linux?

Doesn't ring any bells at all. I guess you'd have to resort to printf-debugging, just \
like I've done for other bugs. The last thing I can think of on the spot is that the \
problem night be in this Qt 4.8.3, it seems to be some beta or stuff because it isn't \

No idea here. Make sure you have Qt debugging symbols and you've built the SMOKE libs \
and assemblygen in CMAKE_BUILD_TYPE=Debug (I can see you have debugging symbols but \
no line numbers, for example). Another thing I do when debugging is going to \
assemblygen/src/main.cs and adding these 2 lines:
cp.IncludeDebugInformation = true;
cp.TempFiles.KeepFiles = true;
to the setting up of CompilerParameters.

Another note: that QVariant.FromValue<float> crash I've written about, I'm alomost \

assemblies displayed automatically in the list, and things compiled just fine. Duh.
When I tried to run, it got past the QApplication creation (a good sanity check), but \

I've just tried my project on Windows with the build with all of your patches \
included and it ran fine. You may check if Qt is either in your path or \
libgcc_s_dw2-1.dll, mingwm10.dll and the Qt libs themselves (like QtCore4.dll, \
QtGuid4.dll, etc.) are in the same dir as your executable. About Linux it's possible \
that some dependency is missing. You may try the following in a terminal:
MONO_LOG_LEVEL=Debug mono /path/to/your/exe
This will show you how each individual library is loaded and you'll find the missing \
or incorrect one.

I successfully compiled my project under Windows, and tried to run it, but it just \
hung. It didn't even get to the first line of my Main() function, which is the \
creation of a new QApplication. There's no apparent debug output, either.
Under Linux, after installing the version of Qyoto I built, I tried to select the new \
assemblies, but they didn't show up in the list (even though they're installed under \
/usr/lib/mono/gac with the proper gacutil signing and all that). I could select \
them by browsing the filesystem, though. However, compilation crashed with \
"System.TypeLoadException: Could not load type 'Qyoto.QMainWindow' from assembly \
'qyoto-qtgui, Version=2.0.0.0, Culture=neutral, PublicKeyToken=194a23ba31c08164'." \
But I could open the assembly in MonoDevelop and browse it. I could even look at \
QMainWindow.
Sigh...I should have known that building Qyoto was going to be the least of my \
trouble. :-)

The QColor-containing QVariant was for my override of QAbstractItemModel, in the \
method "public override QVariant Data (QModelIndex a_rIndex, int a_iRole)", when the \
role was Qt.ItemDataRole.BackgroundRole, i.e. so I could give my tree-items a \
background color. I can't use GlobalColor because I use different colors, and some \
of them have transparency. I'll look into QVariant.FromValue<T>.
Enclosed is my initial .spec file. This works under Fedora Core 16, and does \
everything I want except install the cmake files with the "devel" package. The \
enclosed patch causes the key.snk file to get installed so that it can become part of \
the "devel" package.
In the standard "qyoto" package, cmake/CMakeLists.txt contained this section for \
installing the cmake files:
install(FILES CMakeCSharpCompiler.cmake.in
CMakeCSharpInformation.cmake
CMakeDetermineCSharpCompiler.cmake
CMakeTestCSharpCompiler.cmake
FindMono.cmake
${CMAKE_CURRENT_BINARY_DIR}/QyotoConfig.cmake
DESTINATION share/qyoto/cmake )
But I'm not sure where to put the equivalent of that in the assemblygen project.
At some point I'll update the assembly versions to read 4.8.3. Probably around the \
time I attempt the .NET 3.5 backport.

Subject: Re: [Kde-bindings] Building latest qyoto under Windows and Linux
I checked it and I actually find it strange that there ever was a constructor of \
QVariant taking a QColor, see this excerpt from the Qt 4.8.0 docs on QVariant: "A \
Note on GUI Types Because QVariant is part of the QtCore library, it cannot provide \
conversion functions to data types defined in QtGui, such as QColor, QImage, and \
QPixmap. In other words, there is no toColor() function."
What you have is a constructor that takes a Qt.GlobalColor, an enum of built-in \
colours. If it doesn't work for you you can simply use QVariant.FromValue<T>. About \
event raising methods: come to think of it, they do not seem to depend on the event \
handler type so I'll try them tomorrow.
I think it's most clear if the Qyoto RPM bears the version of Qyoto, and the version \
of Qyoto is most clear to bear the version of the wrapped Qt version so basically I \
agree with you.

OK, I'll attempt the .NET 3.5 backport, hopefully today. (I really need to do some \
non-Qyoto things this weekend...like cook next week's lunch. :-)
Will you be able to implement QVariant<QColor> and OnDataChanged() relatively soon? \
Then I can start testing my project under the newest Qyoto.
I was working on an RPM spec file for the latest qyoto (i.e. so that it can be \
installed with Linux's package manager), and noticed that all the assembly versions \
are set to 2.0.0. Should we upgrade them to match the version number of the Qt \
library that we're compiling them against (in my case, 4.8.3)? Or are they supposed \
to match the version of .NET that they run with? I'm not really sure what the \
standard is, but it seems like they should be upgraded past 2.0.0.

Well, in short, right now nobody cares about Kimono. :)
About .NET 3.5, the following needs to be done:
1. Define all Qyoto.Action overloads (for example, in \
assemblies/qyoto-qtcore/Qyoto.cs); 2. Change src/plugins/qyoto/QyotoHooks.cs, method \
PostMembersHook; you'll see where I use System.Action; as you won't have a reference \
to Qyoto.Action you'd need to change the Windows case to use only strings for \
generation, not very hard a task.
And you're done.
About Emit.DataChanged: I think now that even though that calling the signal didn't \
help you it'd be nice to have an event raising method (OnDataChanged, as you said), \
it's both good practice and, I'd say, a .NET/Mono library "standard". I'll think \
about adding such but after the migration (if any) to Qyoto.Action because it'd have \
to be tested twice otherwise.

Subject: Re: [Kde-bindings] Building latest qyoto under Windows and Linux
I was converting the patch format while you were sending the second e-mail, so it was \
just timing. :-) There's no problem at all submitting future patches in the git \
format -- I will do that.
Emit.DataChanged is an event now, so I can't call it as a function. I also didn't \
see an OnDataChanged() method. I'm sure there's some way to post an event to an \
object directly in C#, I just don't know what it is. I can look it up. But like I \
said, for the short term, the problem is moot -- it never did what I wanted anyway. \
Some day I'll have to get better with Qt and figure out how to use tree-views better.
Re: the Kimono port, I just didn't know if it contained the "latest" Kimono the way \
the assemblygen project contains the "latest" Qyoto. I don't use Kimono personally. \
I was just wondering if anyone cared if assemblygen's Kimono wasn't building.
Re: .NET 3.5, if I can figure out how to make the change I'm talking about, I will. \
Where I work, they're still using .NET 3.5 under Windows Vista, which is my entire \
motivation for caring about .NET 3.5. They're talking about finally upgrading to \
Windows 7, but it hasn't happened yet. Presumably we'll upgrade to .NET 4 at the \
same time. (And before you say anything...yes, my workplace is a time warp. It's \
just one of my crosses to bear. :-)

I've already been able to successfully apply all your patches (you may've missed my \
second e-mail) but the new format you've sent me (assemblygen-patches-git.zip, no \
need for the other one) allows me to use Tortoise Git! So it'd be great if you could \
send all of your future patches in this one.
Thanks for your kind words about my changes. :)
I haven't deleted any constructors from QVariant, I don't know how that happened. \
Will check it right now. About Emit.DataChanged, what is the difference now - is it \
not accessible (private), is it missing or sth else?

It looks like the output of "diff -ur" and "git diff" are slightly different. \
Either that's the problem, or it's an issue of Windows-style line-endings (i.e. \
CR/LF) versus Linux-style line endings (i.e. LF). Enclosed are two archives with \
patches generated by "git diff". One has Linux line endings, the other has Windows \
line endings. One or both should work for you.
I was able to run uics under Windows, and I made a bunch of little changes to adapt \
to the new API. Very slick! All the set/get methods have been replaced with \
properties, the enum values allow the "bitwise or" operator, and the Qt events are \
now C# events!
I have two API changes I haven't resolved yet. One, QVariant no longer has a \
constructor that takes a QColor. I need this to color my tree-view items. Also, I \
can no longer call "Emit.DataChanged" from within my QAbstractItemModel subclass. I \
was using that to force the update of the display of my tree-view when I modified \
items. But I never got that to work anyway; I ended up having to call Collapse() on \
the parent item and have the user re-open that item in order to force the update. \
So maybe this second one isn't a big deal. But I'll definitely need a QVariant \
constructor that takes a QColor.

They all look great but I cannot apply them. I use the "Review/apply single patch" \

Subject: Re: [Kde-bindings] Building latest qyoto under Windows and Linux
OK, I separated out all my patches. Enclosed is an archive with all of them. They \
are meant to be applied in order, but if they're not, or one is skipped, they should \
work, but patch will report "fuzz", i.e. that the target line numbers had to be \
adjusted.
Patch 1 allows MONO_EXECUTABLE to be undefined, i.e. so that the Windows version can \
be built with Microsoft's C# compiler.
Patch 2 modifies output-destinations, so that executables, libraries, and assemblies \
go to the proper location, and it modifies Windows libraries/DLLs so that they don't \
have a "lib" prefix. Patch 3 is the patch that detects a missing QtDBus (i.e. under \
Windows) but allows building anyway. Patch 4 fixes qyoto-phonon to use \
DEF_LIST_MARSHALLER instead of DEF_VALUELIST_MARSHALLER. I hope I did it right. \
Patch 5 makes the build look for the .NET 4 compiler under both Windows and Linux. \
Patch 6 adds "SMOKE_INCLUDE_DIR" to a few places where it's needed. Patch 7 builds a \
native assemblygen under Windows, so that it can load native DLLs. Patch 8 is the \
hack that adds a reference for the Error class under QX11EmbedContainer and \
QX11EmbedWidget.
I noticed that Kimono isn't building under Linux. Is the Kimono project in the \
assemblygen git-project being used or maintained? I started to modify the \
CMakeLists.txt files to build it, but it looks like it needs more work than that.
One last thing...are there any other dependencies on .NET 4, or is it just the \
System.Action<> prototypes with more than 4 parameters? If so, can we just add our \
own "Qyoto.Action<>" prototypes with the required number of parameters, and use those \
instead? Would that cause any headaches that I can't think of? (In which case, \
patch 5 can be ignored.)

Subject: Re: [Kde-bindings] Building latest qyoto under Windows and Linux
It seems to me you haven't subscribed to the mailing list because I've been doing \
quite a bit of shouting here. :) Please consider joining, this way you'll always be \
up to date with all developments.
Most of the errors you report are my fault, sorry about that:
1. QX11EmbedContainer and QX11EmbedWidget - I removed them because the nested type \
Error was not generated; I didn't check that as I was after another bug then so \
seeing they are not that often used I just removed them; obviously I forgot to remove \
the events that use them; I compiled everything then but apparently these events are \
new to Qt 4.8.0 as my Linux had 4.7.4;
2. dmcs - I really don't know what happened here; I clearly remember searching for \
"gmcs" in the whole dir and replacing it; it seems that I didn't commit these \
changes;
3. DEF_VALUELIST_MARSHALLER - I replaced this everywhere with DEF_LIST_MARSHALLER \
because of two of the bugs (QPrinterInfo and QModelIndex) I've written about in my \
recent post called "Qyoto: help needed"; but I have clearly forgotten about Phonon as \
I don't compile it on my Windows because of some missing dependencies;
4. uics - Arno advised me months ago to move uics to assemblygen but I haven't done \
it yet; I will complete that today.
You can send me your patches and I'll push them but please try to separate them per \
feature: that is, one for dmcs, one for DBus, one for MONO_EXECUTABLE, etc.

Subject: Re: [Kde-bindings] Building latest qyoto under Windows and Linux
OK, I added two lines to src/plugins/qyoto/QyotoTranslator.cs:
{ "QX11EmbedContainer::Error", delegate { throw new NotSupportedException(); } },
{ "QX11EmbedWidget::Error", delegate { throw new NotSupportedException(); } },
I don't know if that was a great idea, but at least it kept compiling.
The next compile error (under Linux) was in qyoto-phonon:
assemblygen/assemblies/qyoto-phonon/native/phononhandlers.cpp:29:25: error: expected \
constructor, destructor, or type conversion before ‘(' token
The issue seems to be that DEF_VALUELIST_MARSHALLER isn't defined anywhere. \
assemblies/qyoto-qtcore/native/marshall_macros.h has a definition for \
DEF_LIST_MARSHALLER, so maybe that file is out of date.
As always, help is appreciated.

Subject: Re: [Kde-bindings] Building latest qyoto under Windows and Linux
I've been here the whole time...you could have just shouted!
I'm still overloaded at work, but decided to take some time today to work on this \
anyway. I'm tired of being too tired to work on projects that I want to work on! \
:-)
If Qyoto has to depend on .NET 4, that's not a big deal -- if it needs to use \
System.Action<> instances with more than 4 parameters, there's not much of a choice. \
The problem was that cmake/modules/CMakeDetermineCSharpCompiler.cmake was still \
looking for the v3.5 compiler. So I updated it to look for the v4.0.30319 \
compiler. I also updated to look for dmcs (i.e. the .NET 4 version of Mono) instead \
of gmcs. How is it that assemblygen ever compiled without these changes?
The next barrier was that the most of the changes I submitted a long time ago had \
never been applied. I had modified assemblies/qyoto-*/CMakeLists.txt to make them \
work if MONO_EXECUTABLE was undefined, and various places to allow \
QT_QTDBUS_LIBRARY to be undefined. I put those back.
Now assemblygen builds and links under Windows, but I haven't tried to run it yet.
Under Linux, I get as far as building qyoto-qtgui, then I get a bunch of errors like \
"error CS0426: The nested type `Error' does not exist in the type \
`Qyoto.QX11EmbedContainer'". One example of a line that causes this problem is:
[Q_SIGNAL("error(QX11EmbedContainer::Error)")]
event System.Action<QX11EmbedContainer.Error> Error;
If you know how to get past this, I'd be grateful. The only reference I see to \
QX11EmbedContainer is in src/plugins/qyoto/QyotoTranslator.cs, where it throws a \
NotSupportedException, so I have no idea where to go with this.
Also, I have some vague memory that uics was branched into assemblygen? If not, \
what do I use?
Thanks in advance for any help with these issues!

I'm glad you're back, Steven!
Both problems are one and the same: Qyoto now depends on .NET/Mono 4.
The reason is that I needed the overloads for System.Action as I use them to generate \
events corresponding to signals. The other thing I need to find the files with \
parameter names. If the dependency on .NET 4 is unacceptable for you please say so \
and we might be able to think of some workaround.

Subject: [Kde-bindings] Building latest qyoto under Windows and Linux
Today I decided to try to build latest smokegen/smokeqt/assemblygen under Windows and \
Linux. smokegen, i.e. git://anongit.kde.org/smokegen, and smokeqt, i.e. \
git://anongit.kde.org/smokeqt, built and linked under both Windows 7 and Fedora Core \
16 just fine.
But when building assemblygen, i.e.git://gitorious.org/assemblygen/assemblygen.git, \
"assemblies" branch, I get the same build error immediately, under both OSes:
GeneratorData.cs(220,98): error CS0117: `System.Environment.SpecialFolder' does not \
contain a definition for `Windows'
Getting that error under Linux didn't surprise me, but getting it under Windows did.
Diking that line out and continuing to build, I get to building qyoto-qtcore.dll. \
I get 260 "Won't wrap method" warnings and 65 "Conflicting names" messages, then I \
get a bunch of errors that say "error CS0305: Using the generic type \
`System.Action<T1,T2,T3,T4>' requires `4' type argument(s)". One example of a line \
that generates such an error is:
[Q_SIGNAL("rowsAboutToBeMoved(QModelIndex,int,int,QModelIndex,int)")]
event System.Action<QModelIndex,System.Int32,System.Int32,QModelIndex,System.Int32> \
RowsAboutToBeMoved;
I'm guessing there's a 'System.Action<T1,T2,T3,T4>' now, but my version of Qt \
(4.8.1-5) doesn't have that.
So...does anyone know what to do about these? The first error appears to be real; \
the second one appears to want a different version of Qt. What version of Qt should \
I be using?

</span><span>QX11EmbedContainer and </span>QX11EmbedWidget - I removed them because \
the nested type Error was not generated; I didn't check that as I was after another \
bug then so seeing they are not that often used I just removed them; obviously I \
forgot to remove the events that use them; I compiled everything then but apparently \
these events are new to Qt 4.8.0 as my Linux had 4.7.4;<br></div><div><span>2. dmcs - \
I really don't know what happened here; I clearly remember
searching for "gmcs" in the whole dir and replacing it; it seems that I didn't \
commit these changes;<br></span></div><div><span>3. </span>DEF_VALUELIST_MARSHALLER - \
I replaced this everywhere with DEF_LIST_MARSHALLER because of two of the bugs \
(QPrinterInfo and QModelIndex) I've written about in my recent post called "Qyoto: \
help needed"; but I have clearly forgotten about Phonon as I don't compile it on my \
Windows because of some missing dependencies;<br></div><div><span>4. uics - Arno \
advised me months ago to move uics to assemblygen but I haven't done it yet; I will \
complete that today.</span></div><div><br><span></span></div><div><span>You can send \
me your patches and I'll push them but please try to separate them per feature: that \
is, one for dmcs, one for DBus, one for </span><span>MONO_EXECUTABLE, \
etc.<br></span></div><div><br></div> <div style="font-size: 12pt; font-family: \

"><span>If Qyoto has to depend on .NET 4, that's not a big deal -- if it needs to \
use System.Action<> instances with more than 4 parameters, there's not much of \
a choice. The problem was \
that cmake/modules/CMakeDetermineCSharpCompiler.cmake was still looking for the \
v3.5 compiler. So I updated it to look for the v4.0.30319 compiler. \
I also updated to look for dmcs (i.e. the .NET 4 version of Mono) instead of \
gmcs. How is it that assemblygen ever compiled without these \
changes?</span></div><div style="font-size: 12pt; font-family: times, serif; \
"><span><br></span></div><div style="font-size: 12pt; font-family: times, serif; \
"><span>The next barrier was that the most of the changes I submitted a long time ago \
had never been applied. I had modified assemblies/qyoto-*/CMakeLists.txt to make them \
work if MONO_EXECUTABLE was undefined, and various places to \
allow QT_QTDBUS_LIBRARY to be undefined. I put those \
