[Mesa3d-users] XQueryExtension problem ?

[M. B. <ser...@ne...>]

Hi

I find on internet morpheus-0.3 project.

and had had this problem:
#gdb morpheus
GNU gdb Red Hat Linux (5.3.90-0.20030710.41rh)
This GDB was configured as "i386-redhat-linux-gnu"...Using host
libthread_db library "/lib/libthread_db.so.1".

(gdb) run
Starting program: /usr/local/bin/morpheus
[Thread debugging using libthread_db enabled]
[New Thread 16384 (LWP 7185)]

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 16384 (LWP 7185)]
0x40328227 in XQueryExtension () from /usr/X11R6/lib/libX11.so.6
(gdb) bt
#0  0x40328227 in XQueryExtension () from /usr/X11R6/lib/libX11.so.6
#1  0x404c07b3 in glXQueryExtension (dpy=3D0x0, errorBase=3D0x0,
eventBase=3D0x0) at glxcmds.c:758
#2  0x40470884 in gdk_gl_query () from /usr/lib/libgtkgl.so.5
#3  0x0804b8d4 in main (argc=3D1, argv=3D0x40473150) at main.c:189

The gdk_gl_query function comes in gtkglarea-1.2.2-17 rpm.

finding gdk_gl_query in code, only this lines in ./src/main.c

if( gdk_gl_query() =3D=3D FALSE ) {
	g_print( "no OpenGL capability\n" );
        return 0;
}

Well, I deleted this 4 lines from code and morpheus works well.

I try this with mesa from cvs+savage dri and in other computer with
XFree4.4 from cvs and with X.org R6.7 compiled from sources,
the difference was when morpheus runed with XFree4.4 instead of
Segmentation fault, gdk_gl_query() return FALSE.

any comments ?=20
thanks,
