I get the following error when compiling the r225:

I am using ubuntu 12.04 with a Nvidia NVS 4200M graphics card.

Is this the demo one that fails ?

Same error for me, cannot compile freetype_gl because of the undefined 
reference to glTexImage2D.
Maybe a -lGL is missing somewhere ? 

I am using ubuntu 12.04 as well

Sorry for the long delay.

Do other demos run ok ?

Hello
Having same issue!
Ubuntu 12.04 x86_64

Seems like it links with wrong DSO (mesa instead of nvidia) -- 
ls -lah /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/libGL.so
lrwxrwxrwx 1 root root 13 Jun 19 00:54 
/usr/lib/gcc/x86_64-linux-gnu/4.6/../../../x86_64-linux-gnu/libGL.so -> 
mesa/libGL.so
This bug (check https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/943162) 
happens with some other software. With normal compile-time direct linking 
everything works. Maybe with static library ("/usr/bin/ld: 
libfreetype-gl.a(texture-atlas.c.o)") this bug occures too..
By the way, "export LD_LIBRARY_PATH=/usr/lib/nvidia-304-updates" makes dlopen 
work, but building freetype-gl still fails (I tried rebuilding from scratch 
after changing LD_LIBRARY_PATH) - this is strange

I forgot to mention, i used r228
and demos do work
Is makefont considered a demo too? :)

Yes makefont is supposed to build a header file that contain a whole font 
(well, some characters) and  is used by demo-makefont.

Could you open the issue on github ? (it is now the official repository )
