glXGetProcAddress back in 0.10...?

Gothi[c] · Post by **Gothi[c]** » Fri May 27, 2005 6:24 am

../../lib/Linux/libIrrlicht.a(COpenGLDriver.o)(.text+0x103a): In function `irr::video::COpenGLDriver::loadExtensions()':
: undefined reference to `glXGetProcAddress'

the good old all familiar error...
i get everything to compile fine in 0.9 after i altered it following the instructions in the thread on this forum, after examining the code in 0.10 in OpenGLDriver.cpp i saw that there was an attempt to fix this, with:

#ifdef GLX_VERSION_1_4
glXGetProcAddress(reinterpret_cast<const GLubyte*>("glActiveTextureARB"));
#else
glXGetProcAddressARB(reinterpret_cast<const GLubyte*>("glActiveTextureARB"));
#endif

i tried forcing it to use glXGetProcAddressARB by removing the #ifdef, which didn't work, then i tried the opposite, by leaving only glXGetProcAddress, which didn't work either :shrug:

.. then tried finding out what my system uses:

bash-2.05b# cat /usr/include/GL/glx.h | grep glXGetProcAddress
extern void (*glXGetProcAddress(const GLubyte *procname))(void);
extern void (*glXGetProcAddressARB(const GLubyte *procName))( void );

both appearantly...

as everything compiles fine in 0.9 i'm sure there's nothing wrong with my glx, so there needs to be something changed in the irrlicht source, i tried all the changing i could, but now i'm beyond ideas.

Anyone got a clue? (or flame me if i missed something incredibly obious, which is likely, cause i haven't had any sleep for a while :p )

No, not at all. Now I'm a little bit confused. Someone else got that problem or has a solution, an idea, anything?

It's working for me as it should. Both Suse and Debian are working. Maybe you're linking in a wrong order? Could you please check your OpenGL versions (of all header files) and post also your final compiler command? did you try the examples from SDK?

compiling...
--------------------------------------------------------------------------------------

to compile irrlicht 0.10 i did:
make clean (to clean previous attempts)
make

Which finished with no errors and created libIrrlicht.a and copied it to the lib dir.

then i tried compiling the hello world demo with:

make

which results in:

g++ main.cpp -o example -I"../../include" -I"/usr/X11R6/include" -L"/usr/X11R6/lib" -L"../../lib/Linux" -lIrrlicht -lGL -lXxf86vm -lXext -lX11

: undefined reference to `glXGetProcAddress'
collect2: ld returned 1 exit status
make: *** [all] Error 1

if i re-compile 0.9 with the same commands and then compile the 0.9 hello world it works...

I don't know yet what's up there. But I spotted a copy and paste error in the second round of getProcAdress calls in ifdef GLX_VERSION_1_4. It alwas checks for glActiveTextureARB but should check for glClientActiveTextureARB the second time. Use the patch provied on my patch page to fix this and clean up the ARB handling.

Ah, wow, I didn't see that. I guess that's the reason why the multitextureing doesn't work anymore on Linux.

Some people using my games made with Irrlicht said me that it is not working because it do :

Code: Select all

Irrlicht Engine version 0.10.0
Linux
Creating X window...
Starting fullscreen mode..
. OpenGL Renderer.
OpenGL driver version is 1.2 or better.
Multittexturing active.
./Projet1: relocation error: ./Projet1: undefined symbol: glXGetProcAddress

or

Code: Select all

Multittexturing active.
./IrrAdventure: symbol lookup error: ./IrrAdventure: undefined symbol: glXGetProcAddress

do you have a solution ?

P.S.: Someone shows me this link :
http://www.clanlib.org/docs/FAQ.html
where there seems to be the same problem for the Clanlib library.
