Summary: make's configure cross compiling on Ubuntu
Initial Comment:
I was waiting to cross compile make on Ubuntu and was having a problem that WINDOWS32 \
wasn't defined. It turned out to be because the configure file is slightly wrong for \
the naming of mingw on Ubuntu.
On Ubuntu mingw is mingw32msvc so the configure file doesn't create the correct \
config.h because:
case "$host" in
*-*-mingw32)
doesn't match mingw32msvc. Simply adding a wildcard on the end of mingw32 makes it \
match, and thus create the correct config.h, thus build. The fix is replace the above \
with the below.
case "$host" in
*-*-mingw32*)

Summary: MinGW option: check buffer overflow
Initial Comment:
Hi,
I wanted to know if there were a MinGW option allowing to check a buffer overflow.
For example, I would like a warning with the following code:
int tab[10];
tab[20]=3;
I know that there is this option with in Visual C++ (/GS (Buffer Security Check)), \
but with MinGW?
Thanks,

Message:
This is a user error in specifying the host for which the package is to be
residing for. You should specify --host=mingw32 to resolve this issue.
There is no such system as mingw32msvc.

Summary: MinGW Compiler Flag issue, -Wall
Initial Comment:
I Believe there is a bug in the
ld.exe
linker...
cpuZ
and Speccy which uses the cpuID code
are failing to run properly
Speccy is telling me it cannot load the SPC dll....
what ever that is @_@ ?_?
here is the command line I used:
g++ -Wall -March=686 -s -O3 -m32 -o TConverter_C++.exe TConverter_C++.cpp
I originally tried (the basics):
g++ -s -o TConverter_C++.exe TConverter_C++.cpp
I felt in the mood and started to port a bit of my Temperature
converter app from C to C++
after redoing a C and C++ Hello world App from memory
though I only studied C in college 10 & 11 yrs ago...
I did look up a bit of C++ to write a basic hello-world app..
and used from what I remember to code this I'll attach
Dependency Walker text files bellow as well a copy
of my Temperature converter app
after having worked out a few lol bugs as it were it compiles just fine...
so
the in the file
DependecyWalker_normal__CC1PLUS.txt
when I ran the compiler (G++) that time...
I had made a single change that would prevent linking to try and narrow down where \
the bug was occurring.. note the linker (ld.exe) did not run...
I restarted Speccy and cpuZ afterwards...
they ran fine...
I undid the temp bug (just a classic, missing a ';' lol)
re ran through Dependency Walker to catch it all, or at least what ever Dependency \
Walker can catch... using:
-s -m32 -o TConverter_C++.exe TConverter_C++.cpp
and.... lol WoW Speccy seems to be running normally....
so I ran my App... (9KB)
O_O ;_; bug/issue did *Not* occur o_O
Run-Ok: {g++ -s -m32 -o TConverter_C++.exe TConverter_C++.cpp}
Run-Ok: {g++ -s -O3 -m32 -o TConverter_C++.exe TConverter_C++.cpp}
Run-OK: {g++ -March=686 -s -O3 -m32 -o TConverter_C++.exe TConverter_C++.cpp}
Compile&Link:Ok {g++ -Wall -s -O3 -m32 -o TConverter_C++.exe TConverter_C++.cpp}
When I go to run my App then I ran Speccy... It FAILS to function normally!...
so I narrowed it down to the '-Wall' switch
I remember it back from my Class days(2001-'02).. but of course I was using the \
CS-Lab's MS Visual Studios then so the -Wall apparently is no good with MinGW... \
no... I guess I was mistaken it is also used in the makefile for zsnes a SNES \
Emulator... I don't remember if I saw it else where or not.. sorry..
Isn't it supposed to be the... Warn on 'ALL' Errors command switch?
-Wall
a system restart is needed to remedy the issue?
So I wonder what the issue is...
If its a bug in my app I do Apologize I don't mean to waste anyone's time loi.

}
so they would compile at the same time...
Speccy, and cpuZ, both load after... so it seems more likely its a
byproduct of the flag and not so much the Compiler/Linker itself?
I executed the "normal" one 1st, aok, Speccy and cpuZ load fine.
I then ran the one compiled with the "-Wall" compiler flag, through
Dependency Walker
ok app loaded waiting for my Temperature input... Speccy loads...
I enter a temperature... I get an output, Speccy Runs again...... waiting
at {cin.get();} holding the console window open so I can read the
output....
ok just weird... Speccy/cpuZ still ran fine......
The only difference i can think of is I currently, have a Wifi Signal, ie
Internet access... I don't have in-house internet (($$))
I noted two Dependencies as stated in Dependency Walker:
LIBGCC_S_DW2-1.DLL
LIBSTDC++-6.DLL
would such a simple and tiny app not have any dependencies as it would get
compiled into it?
