[PD-dev] [GEM] compiling gem cvs

[Thomas Grill]

Hi GEM maintainers,

i have had some trouble compiling GEM from cvs for Windows (with VC7):
- i had to change all occurences of GL_BGRA or GL_BGR to GL_BGRA_EXT and
GL_BGR_EXT, respectively (i hope that's exactly the same....)
- in text2d.h the GLTTPixmapFont is defined in the class, but the header
file "GLTTPixmapFont.h" is only included for linux and OSX. There doesn't
seem to be a necessity for that. (and why is FTGL defined for other
platforms but for Windows it is GLTT?)
- the particle and pspray projects have absolute file positions which makes
them practically unusable
- in pspray.cpp, line 139 the pow function is neither float, nor double
precision... it's necessary to make the constant 0.3333f
- there's an interesting warning for glm.c, line 1485 that model->texcoords
is of type GLfloat *, which can't easily be printed as an integer....
(should that be numtexcoords?)

the most important problem is that some of the FT*.c of the GLTT 2.5.2
distribution don't seem to match to their corresponding FT*.h files. They
also have different dates. Which GLTT version is typically used with GEM?

many thanks,
T
