I am trying to compile QT C++ opengl based code on Mac OS X

  • 0

I am trying to compile QT C++ opengl based code on Mac OS X 10.7.2 but it has not been able to find qglviewer.h file.

This is the error I am getting when I compile my code.

    Atlast I contacted QGLViewer Developers and they have fixed this problem. Please follow the instructions given on this link for installation: http://www.libqglviewer.com/index.html

    [Please follow on the above page libQGLViewer2.3.14 Version Release]

    and to compile your own QGLViewer project please follow this link: http://www.libqglviewer.com/compilation.html#pro

    It explains how to create your own .pro file to generate the Makefile.
