[vtk-developers] vtkgl::LoadExtension not exported

[Kathleen S. Biagas]

In our attempts to support OSMesa at runtime, we've run into a snag in
that vtkgl::LoadExtension and vtkgl::GLVersionExtensionsString are not
exported, and thus not accessible in our implementation.

Are there any objections or unforseen-on-my-part consequences to
modifying ParseOGLExt.cxx to export those symbols?

Something along the lines of:

Left file: /VTK-Unmodified/Utilities/ParseOGLExt/ParseOGLExt.cxx
Right file: /VTK-Modified/Utilities/ParseOGLExt/ParseOGLExt.cxx

<   hfile << endl << "  int LoadExtension(const char *name, "
---
>   hfile << endl << "  extern int VTKRENDERINGOPENGL_EXPORT
LoadExtension(const char *name, "
696c696
<   hfile << endl << "  const char *GLVersionExtensionsString();" <<
endl;
---
>   hfile << endl << "  extern VTKRENDERINGOPENGL_EXPORT const char
*GLVersionExtensionsString();" << endl;
