Once nxagent is built in nx-X11/programs/Xserver/nxagent, you should be able
to start it like './nxagent :11'.
ldd ./nxagent shows if it is linked with the right libs.

libpng12.so.0 => /usr/lib/libpng12.so.0 (0x0000002a966ea000)

/lib64/ld-linux-x86-64.so.2 (0x0000002a95556000)
I copied those libX11-nx, libXext-nx, libXrender-nx to /usr/lib so it's
easier for it to be located.
First problem I hit is at lib/X11/IntAtom.c:240
if ((state->atoms[i] = repl->atom))
_XUpdateAtomCache(dpy, state->names[i], (Atom) repl->atom,
(unsigned long)0, idx, 0);
This doesn't sound right. Should it be "if ((state->atoms[i] ==
repl->atom))"?
It's just my vague guess since the author may have omit a comment here
justifying the use of '='. This causes segfault later in _XUpdateAtomCache()
because the state->names[i] is invalid pointer.
Then I tried to make it as '=='. However I got problems in
programs/Xserver/hw/nxagent/Atoms.c:517
if (aMap == NULL)
{
Atom local = MakeAtom(name_list[i], strlen(name_list[i]), True);
The name_list[0] is a NULL pointer and it causes segfault in MakeAtom.
Maybe name_list is not correctly initialized in XInternAtoms() as I am
tampering with it.
Well, that's my attempt so far. Hope this is clear if any of you want to
continue the debugging. Btw, I had to add '-g' in Makefile to generate the
debug information. This is easy once you know the build commands to use.
I am still quite surprised about the package being released in such a shape.
Maybe NoMachine is short of resources as well.
Thanks,
Xiong

I am not sure if it really matters. Just to make it compile.<br>
<br>
Now after nxcomp and nxcompext are built, you should be able to 'make
World' under nx-X11. The directory names are hardcoded in makefile so
you should not rename the directories unpacked from .tar.gz tarballs.<br>
<br>

I don't know much about the Imakefile system so I changed the Makefile
and build again. Some other makefiles are modified accordingly as they
will link with the libX11-nx, libXext-nx, libXrender-nx we just built.<br>
