v0.8 no textures in opengl also in Linux!

[William Finlayson]

I had to use an OpenGL extension loader to get it to work in Linux. extgl it's called. You have to make a few very minor changes to get it to work. I also made changes to the OpenGL materials code and fixed the shadows. I don't have all the changes here, so I can't post them, but if you really want I can send you the sources I'm using, I could send you 0.7 or 0.8 depending on what you are using. If you arent bothered about having the source then I could just send you the binary, or you could download Bindenlicht for Linux, which has it with it.

many thnx William!

but Murphy's fix worked! check this image:

now he's helping me out with a similar problem in Windows.

ps. The only thing in linux is that a weird kinetic effect occurs with horizontal-striped textures ; which seems to be a problem with z-buffer.

thnks; I'd still love to see those sources for 0.8 so if you can email them to me.

The bodies of extGlActiveTextureARB() and extGlClientActiveTextureARB() are empty when compiling under Linux because they're "#ifdef WIN32"ed. If you haven't yet removed those #ifdefs, do so.

Great and Thnx this works on my linux system now.

William I am also interested in the code for the OpenGL materials and shadows fixes.

Here is a summary of the changes in CVideoOpenGL.cpp

Code: Select all

// extensions
PFNGLACTIVETEXTUREPROC pGlActiveTextureARB = 0;
PFNGLCLIENTACTIVETEXTUREPROC pGlClientActiveTextureARB = 0;
PFNGLGENPROGRAMSARBPROC pGlGenProgramsARB = 0;
PFNGLBINDPROGRAMARBPROC pGlBindProgramARB = 0;

// This works. 
// But I am not able to test it out on my machine, because it doesnot have
// any 3d acceleration in Linux, even with new drivers. Uncomment this and set MultiTextureExtension to true if
// you want to use it.
pGlActiveTextureARB = (PFNGLACTIVETEXTUREPROC)glXGetProcAddressARB(reinterpret_cast<const GLubyte*>("glActiveTextureARB"));
pGlClientActiveTextureARB = (PFNGLCLIENTACTIVETEXTUREPROC)glXGetProcAddressARB(reinterpret_cast<const GLubyte*>("glClientActiveTextureARB"));

MultiTextureExtension = true;


...........


void CVideoOpenGL::extGlActiveTextureARB(GLenum texture)
{
//#ifdef WIN32
	if (MultiTextureExtension && pGlActiveTextureARB)
		pGlActiveTextureARB(texture);
//#endif
}

void CVideoOpenGL::extGlClientActiveTextureARB(GLenum texture)
{
//#ifdef WIN32
	if (MultiTextureExtension && pGlClientActiveTextureARB)
		pGlClientActiveTextureARB(texture);
//#endif
}
