conflicting header file with gl.h

[adi_himawan@…]

I'm trying to install enblend and got the following errors

/opt/local/include/GL/gl.h:1737: error: conflicting declaration 'typedef void (* PFNGLTEXIMAGE3DPROC)(GLenum, GLint, GLenum, GLsizei, GLsizei, GLsizei, GLint, GLenum, GLenum, const GLvoid*)'

My guess is it is because gl.h in my mac define the macro X_GL_H instead of gl_h_ or GL_H

These are a few lines from my gl.h

#ifndef __X_GL_H
#define __X_GL_H

Hi all, I am sorry if this is not good question, but I can't find solution. I've tried to build some libraries and I got the errors:

I saw that someone before had similar problem, but I can't find solution. :( Can anybody help me... Thank you in advance, Natasa

1. Use WikiFormatting (added for you).
2. Check if your comment is present before posting it again (duplicate deleted).
3. If you're going to reopen a ticket, reopen the original, not a duplicate.
4. Your problem is different anyway, apparently involving building your own code, not the enblend port. This is not a MacPorts bug.
