(Knoppix --> Debian Sid)

Ciao,
ho installato g++ con tutti i files richioesti da apt-get, ma quando do il make ottengo:

root@linuxbox:/home/giorgio/software/nick_system/nik_system# make
g++ -c src/nik_system.cc

Ovviamente, se lo lancio:

root@linuxbox:/home/giorgio/software/nick_system/nik_system# ./nik_system
nik_system: freeglut_window.c:300: fgOpenWindow: Assertion `window->Window.VisualInfo != ((void *)0)' failed.
Abortito

Cosa gli manca ?
