Compiling under Linux

[Tels]

Moin,

When try to compile the source code under Linux, I get this error:

g++ -c CVideoOpenGL.cpp -o CVideoOpenGL.o -I"include/" -DIRRLICHT_EXPORTS=1

Do I miss some header files or is there something wrong with the source or makefile?

"installing" the pre-compiled libIrrlicht.a and compiling/running the examples worked great, but I wanted to play around more with Irrlicht.

Here are some details:

SuSe 8.2, running Nvidia's driver (h/w accel. OpenGL), gcc/g++ v3.3.3 (just installed). If you need any additional details, just ask.
Best wishes,

Moin,

to warm-up, I tried to compile the techdemo. Since this failed, too, I added some files (Makefile, main_linux.cpp), and fixed some linux-specific problems and got it to run under linux.

A page where you can find the patch (or an archive with the changes), screenshots, and some experiences:

Cheers,

If you add GL_GLEXT_LEGACY 1 as define, do the glClientActiveTextureARB problems dissappear?

I simple used the source posted over here:

http://irrlicht.sourceforge.net/phpBB2/ ... php?t=1533

and it compiles fine :-) I think we need a central developer forum for this, because two threads discussing the same in Beginners and Advanced is strange :)

Cheers,
