[Opengc-devel] OpenGC Linux status

[Damion S. <da...@op...>]

Hi folks,

I've been a bit busy lately but I'm pleased to announce that after a 
great deal of headache setting up a new Linux machine at home, I've 
been able to build OpenGC successfully. I received several emails from 
people that I did not respond to because of not having a machine to 
test things on, so hopefully this will address those questions. There 
were two changes I had to make to the source (in the opengcnew 
repository) to allow compilation, and I also made the following notes:

FLTK built fine (version 1.1.4).

Freetype built fine (version 2.1.7).

When building FTGL (version 2.07 I think) I had to create a symlink in 
the X11 libraries directory to libGL.la installed under /usr/lib. This 
may be a peculiarity of the NVidia graphics driver I installed, but 
it's something to keep in mind.

When building Plib (version 1.6) I needed to install the libmesaglut 
and libmesaglut-devel libraries first - we do not need the glut 
dependent portion of plib but unfortunately there's no obvious way to 
turn it off.

A few people have asked about CMake. Under Linux if you do a "make 
install" on Freetype, FTGL, and Plib CMake should find the relevant 
files _automatically_. You will need to manually specify 
"Plib_INCLUDE_DIR", which as the ccmake interface notes means "What is 
the path where the file ssgconf.h can be found". On my machine, which 
is probably typical of most linux boxes, this is /usr/include/plib. I 
also had to manually edit one of the plib library names, but I forget 
which offhand.

You should _never_ need to edit a CMakelists.txt file in order to get 
OpenGC to build. If you need to, either you're doing something wrong or 
I've set things up incorrectly. Please let me know if you have trouble.

As a final note, I have not tested any of the data sources under Linux, 
so I have not idea what is working and what isn't. Hopefully I'll be 
able to check on this in the next week or so.

Cheers,
