[Mingw-users] mingw, qt, opengl and multi-texture ?

[Christian W. <cwi...@nh...>]

Dear All, 

I recently started using mingw to port my qt4 programs from Linux
to Windows. My collegues here at the hospital mainly use Windows, 
and I would be happy if the could use my apps. I was already 
successful with one of my programs. It uses OpenGL, which is an 
important requirement for my software. 

I am currently struggeling with a more elaborate program, which makes
use of multi-texturing in OpenGL. Unfortunately, gcc under mingw tells
me that the multi-texturing variables & function are undefined. Here is a 
snapshot of the compiler output. 

...
   glimageview.cpp: In member function `virtual void GLImageView::paintGL()':
   glimageview.cpp:138: error: `GL_TEXTURE0' undeclared (first use this function)
   glimageview.cpp:138: error: (Each undeclared identifier is reported only once for each function it appears in.)
   glimageview.cpp:138: error: `glActiveTexture' undeclared (first use this function)
   glimageview.cpp:142: error: `glMultiTexCoord2f' undeclared (first use this function)
...

Is it somehow possible to enable multi-textureing under mingw? It works
fine when compiled in Linux. Is it possible to use libmesa under mingw to
get it working? 

I would greatly appreciate any comments or suggestion.
