Here is the code:
...
::glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, nWidth, nHeight, 0, GL_RGBA,
GL_UNSIGNED_BYTE, pData);
Here is the bug:
From glTexImage2D doc:
void glTexImage2D( GLenum target, GLint level, GLint components, GLsizei width, GLsizei height, GLint border, GLenum format, GLenum type, const GLvoid *pixels );
Parameters
target The target texture. Must be GL_TEXTURE_2D.
level
The level-of-detail number. Level 0 is the base image level. Level n is the nth mipmap reduction image.
components The number of color components in the texture. Must be 1, 2, 3, or 4.
So components cannot be GL_RGBA, because, from /usr/include/w32api/GL/gl.h:
#define GL_RGBA 0x1908
How such code could survive when compiled with Borland's or M$'s compiler (as you claimed) is beyond my understanding, but frankly, I doubt it does.
