The code in question looks like this:
unsigned char* data = read_png_file (m_file_name);
GLuint texture_id;
glGenTextures (1, &texture_id);
glBindTexture (GL_TEXTURE_2D, texture_id);
set_gl_parameters (data, smooth, mip_map, texture_wrap);
m_texture_name = texture_id;
delete [] data;
ms_image_cache [m_file_name] =
Cached_Image (m_texture_name, m_width_pixels, m_height_pixels);
All of the reference code I could find on google seemed to be similar,
declare the GLuint variable, then initialize it with glGenTextures.
Is there something obviously wrong here?
Any help is appreciated,
