[GRASSLIST:3432] -lGL openlib error on grass57 cvs code

[FRANCESCO]

Hello,

When I compile cvs version of grass57 I get:

....................-lgrass_sites  -o 
/usr/local/grass57/dist.i686-pc-linux-gnu/lib/libgrass_ogsf.so
/usr/bin/ld: cannot find -lGL
collect2: ld returned 1 exit status
make[1]: *** [/usr/local/grass57/dist.i686-pc-linux-gnu/lib/libgrass_ogsf.so] 
Error 1
make[1]: Leaving directory `/usr/local/grass57/lib/ogsf'
make: *** [subdirs] Error 1

Meaning that it does not like my OpenGL when compiling libgrass_ogsf.so

Does anyone know what the problem could be?
I have Mesa5.0-3

Thanks
Francesco
