Linking to glx problem

OpenGL
1

Hi,
I’ve succesfully installed new NVidia drivers and glut-3.7.12 rpms.

Now I have a problem similiar to sglos (posted 4/11/03).

That is, when i try to compile a opengl program, i get the following error messages:

[simon@128-184-88-83 redbook]$ gcc plane.c -o plane -L/usr/X11R6/lib -lpthread -lglut -lGL -lGLU -lXmu -lXi -lXxf86vm
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/…/…/…/libglut.so: undefined reference to glXBindChannelToWindowSGIX' /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/../../../libglut.so: undefined reference to glXQueryChannelDeltasSGIX’
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/…/…/…/libglut.so: undefined reference to glXChannelRectSyncSGIX' /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/../../../libglut.so: undefined reference to glXChannelRectSGIX’
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/…/…/…/libglut.so: undefined reference to `glXQueryChannelRectSGIX’
collect2: ld returned 1 exit status

I agree with PK that this is a linking problem, but using PKs suggestion of using -lXxf86vm has not worked.

Any help would be extremely appreciated…
thanks in advance,
Simon

Could this be a LDPATH problem? (not that I know exactly what that is but I seem to remeber having to export PATHS when using Mesa…

What does your ld.so.conf say?

Here’s mine:

/usr/local/lib
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.2
/usr/lib/opengl/nvidia/lib
/usr/X11R6/lib
/opt/sun-jdk-1.4.1.02/jre/lib/
/usr/qt/3/lib
/usr/kde/3.1/lib

Maybe you also need to add /usr/lib/opengl/nvidia/lib. But I’m just fishing for answers now.

Try compiling with -L/usr/lib/opengl/nvidia/lib if that directory exists on your system.

thanks for replying PK.

here is the file ld.so.conf:
/usr/kerberos/lib
/usr/X11R6/lib
/usr/lib/sane
/usr/lib/qt-3.1/lib

as you can see this is missing many of your values. can this be manually edited or updated?

also, i don’t have a /usr/lib/opengl directory, and hence no /usr/lib/opengl/nvidia/lib.

here’s a locate nvidia output:
[simon@139-132-20-193 etc]$ locate nvidia
/dev/nvidia0
/dev/nvidia1
/dev/nvidia2
/dev/nvidia3
/dev/nvidia4
/dev/nvidia5
/dev/nvidia6
/dev/nvidia7
/dev/nvidiactl
/var/log/nvidia-installer.log
/usr/bin/nvidia-installer
/usr/X11R6/lib/modules/drivers/nvidia_drv.o
/usr/src/linux-2.4.20-8/drivers/ide/pci/nvidia.c
/usr/src/linux-2.4.20-8/drivers/ide/pci/nvidia.h
/lib/modules/2.4.20-8/kernel/drivers/video/nvidia.o

and here’s an locate opengl output:
/usr/share/doc/SDL-devel-1.2.5/html/guidevideoopengl.html
/usr/include/SDL/SDL_opengl.h

any further suggestions greatly appreciated.
cheers,
Simon

Depends on your distro. In gentoo ld.so.conf is updated by the env-update.

Try to locate these files and make sure that they are in your lib path. Either in the LDPATH variable or ld.so.conf.

$ cd /usr/lib/opengl/nvidia/lib/
$ ls
libGL.la libGL.so libGL.so.1 libGL.so.1.0.4191 libGLcore.so libGLcore.so.1 libGLcore.so.1.0.4191

Oh, and by the way, this shared object might be important too.

$ pwd
/usr/lib/opengl/nvidia/extensions
$ ls
libglx.so

I had the exact same linking problems.

I got it working by building the newest Mesa in /usr/local/ and copying the libglut* libraries from src-glut/.lib over the ones in /usr/lib

Not the nicest solution, but it works until Redhat fixes the rpm.

Rebuilding the glut rpm fixes the problem.

great. I have not rebuilt an rpm before. I assume that i need to find the glut src rpm and then build with rpmbuild --rebuild *.src.rpm?

I’ll give it a go and let you know how it goes…

anyone know a link to glut src rpms?

thanks for everbody’s reply. rebuilding the glut source rpm fixes this problem (thanks satan).

for those who have the same problem, download the glut source rpm for RedHat 9 from the link above, remove existing glut rpms (using rpm -e glut) and build source rpm using rpmbuild --rebuild *.src.rpm.

then go to /usr/source/redhat/RPMS/i386 and install the glut and glut-devel rpms using rpm -i glut*.rpm and glut-devel*.rpm.

thats it.
opengl apps will then compile using:
gcc foo.c -o foo -lglut -lGL -lGLU -L/usrX11R6/lib -lXi -lXm

good luck,
Simon

just wanted to say:

rebuilding glut from the src-rpm did not help in my case.
compiling from the normal glut-37.zip either.

what helped my was simply installing the glut and glut-devel packages from rh 8.0.

you can check if the references are in the so-file with “nm -Bgr | grep glX”.

Using the RH8 RPM’s worked for us,
thanks for the tip!
