[FreeNX-kNX] Compiling NX1.5.0 on amd64

[Xiong Jiang]

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.

amd64:/home/jxiong/NX/nx-X11/programs/Xserver# ldd ./nxagent
libXext-nx.so.6 => /usr/lib/libXext-nx.so.6 (0x0000002a9566e000)
libX11-nx.so.6 => /usr/lib/libX11-nx.so.6 (0x0000002a9577e000)
libz.so.1 => /usr/lib/libz.so.1 (0x0000002a95961000)
libm.so.6 => /lib/libm.so.6 (0x0000002a95a75000)
libXpm.so.4 => /usr/X11R6/lib/libXpm.so.4 (0x0000002a95bfa000)
libXcomp.so.1 => /usr/lib/libXcomp.so.1 (0x0000002a95d0b000)
libXcompext.so.1 => /usr/lib/libXcompext.so.1 (0x0000002a95f2e000)
libXrender-nx.so.1 => /usr/lib/libXrender-nx.so.1 (0x0000002a960c5000)
libc.so.6 => /lib/libc.so.6 (0x0000002a961ce000)
libdl.so.2 => /lib/libdl.so.2 (0x0000002a9640b000)
libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x0000002a9650e000)
libpng12.so.0 => /usr/lib/libpng12.so.0 (0x0000002a966ea000)
libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x0000002a96811000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x0000002a96932000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x0000002a96b3b000)
/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
