GLBatch destructor segmentation fault #29

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
When GLBatch is declared but not used - its destructor yields a seg fault.

To fix this issue replace in GLBatch::~GLBatch() this:
#ifndef OPENGL_ES
    glDeleteVertexArrays(1, &vertexArrayObject);
#endif

with this:
#ifndef OPENGL_ES
    if(vertexArrayObject != 0) {
        glDeleteVertexArrays(1, &vertexArrayObject);
    }
#endif

BTW, I'm using Ubuntu 10.10 i386 (and amd64), GeForce 9600GT, Nvidia driver 
v275.09.07, Intel core i5.

There's also other random issues, like ShadedTriangle.cpp in chapter 6 doesn't 
need the ShaderManager, remove obvious comments from all source files (like 
telling that "main" is the program starting point, or that SetupRC() sets up 
the resources, etc), ShutdownRC() doesn't actually get called (at least under 
Linux/Ubuntu), etc, otherwise great book.
