no consigo activar 3D con kernel 2.6.16.21-0.13-smp, cuando voy a instalar el driver de nvidia me da el siguiente mensaje: Using: nvidia-installer ncurses user interface -> License accepted. -> No precompiled kernel interface was found to match your kernel; would you li ke the installer to attempt to download a kernel interface for your kernel f rom the NVIDIA ftp site (ftp://download.nvidia.com)? (Answer: No) -> No precompiled kernel interface was found to match your kernel; this means that the installer will need to compile a new kernel interface. -> Performing CC test with CC="cc". -> gcc-version-check failed: Could not compile gcc-version-check.c. Please be sure you have your distrib ution's libc development package installed and that 'cc' is a valid C compil er name. If you know what you are doing and want to ignore the gcc version check, sel ect "No" to continue installation. Otherwise, select "Yes" to abort install ation, set the CC environment variable to the name of the compiler used to c ompile your kernel, and restart installation. Abort now? (Answer: No) ERROR: You do not appear to have libc header files installed on your system. Please install your distribution's libc development package. ERROR: Installation has failed. Please see the file '/var/log/nvidia-installer.log' for details. You may find suggestions on fixing installation problems in the README available on the Linux driver download page at www.nvidia.com. Una ayudita, que no soy capaz de resolverlo. Joaquín
