OpenGL with glut

[LAJOIE]

hello,
i have done a prog in openGL with glu and glut on solaris. I want to compil it on HP-UX.
I have download and compil glut.
I can compil it but i have always this error :
/usr/lib/dld.sl: Unresolved symbol: XShmQueryExtension (code) from /opt/graphics/OpenGL/lib/libHpGL.2
I am beginer, to compil my source i use :
aCC -I/home/myhome/opengl/glut-3.7/include -I/opt/graphics/OpenGL/include -L/home/myhome/opengl/glut-3.7/lib/glut -L/opt/graphics/OpenGL/lib myfile.c -lX11 -lXi -lglut -lGL -lGLU -lm

If you need more information about my system ask me.

That symbol is defined in libXext.sl.
In general you should link libraries that need symbols before libraries that define those symbols. It is not always necessary when using shared libraries, because a shared library is brought in as one unit. It is still a good habit. I would list -lXext and -lXi before -lX11. Use this library list in your link line-

-lglut -lGL -lGLU -lXext -lXi -lX11 -lm

I try to change my link order but
I still have this error message :

/usr/lib/dld.sl: Unresolved symbol: XShmQueryExtension (code) from /opt/graphics/OpenGL/lib/libHpGL.2
IOT trap

Is there a problem with GL? Can I find tools to check my config?
I can't change my config because I am not root :(

[Mike Stroyan]

Did you actually add -lXext to the link?

You can run /opt/graphics/OpenGL/demos/verify_install-32 to verify the OpenGL installation. There are also demo programs with source and makefiles under /opt/graphics/OpenGL/demos. You could copy those directories to another directory where you have write permission and build the demos.

Thanks,
I can compile stereo and occlusion_cull, I will use those examples to compil my prog.

When I check my install I have this error message :

/usr/lib/X11R6/pa20_64/libXhp11.sl is bad or missing

But as I can compile demos it doesn't seem important

Thks for help

I compile but i have now this error :

/usr/lib/dld.sl: Unresolved symbol: XmuLookupStandardColormap (code) from /home/u181568/citrix/U181568/opengl/glut-3.7/lib/glut/libglut.sl
IOT trap

My problem seems to be in glut
I had to change the makefile to compile glut, I add :
-I/opt/graphics/OpenGL/include
I prefer use the glut-3.7-sd-11.00.depot, but how decompress it without be root?

If it is easier to change my code to no use glut why not!!
I join my source, if someone could explain me how to no use glut.

You can find that missing XmuLookupStandardColormap symbol by linking with "-L/usr/contrib/X11R6/lib/ -lXmu".

There is also a really old version of libglut in /opt/graphics/OpenGL/contrib/libglut that includes its own implementations of the Xmu functions that it uses.

cc -o myfile myfile.c -g -I/opt/graphics/OpenGL/include -I/opt/graphics/OpenGL/contrib/libglut -I/opt/graphics/OpenGL/include/GL -L/opt/graphics/OpenGL/lib -L/opt/graphics/OpenGL/contrib/libglut -lGLw -lglut -lGLU -lGL -lXm -lXt -lXext -lX11 -lm
