Hi performers,

I want to check which GL_EXTENSIONS are available. But I only get empty
strings as result to glGetString.
And eventually I don't get any error messages from glGetError, even if I
call glGetString( 0xABCDEF ).
Does anybody know why? Do I missed out some initialisations ?

Here's my code :

int main( int argc, char *argv[] )
{
  GLenum e;
  GLubyte *ext;

  pfInit();
  pfuInit();
  pfiInit();

  ext = (GLubyte *)glGetString( GL_EXTENSIONS );
  while ((e=glGetError()) != GL_NO_ERROR) cout << "Error " << e <<
endl;

  cout << "ext: " << ext << endl;

  if( strstr((char *)ext,"GL_ARB_imaging" ) ) cout << "GL_ARB_imaging
supported !!!" << endl;
  if( strstr((char *)ext,"EXT_blend_minmax" ) ) cout <<
"EXT_blend_minmax supported !!!" << endl;
  if( strstr((char *)ext,"EXT_blend_subtract" ) ) cout <<
"EXT_blend_subtract supported !!!" << endl;

  ...
}

Thanks, Juergen
