I'm not an expert, but perhaps it does matter what version of gcc was used to build the kernel and what version of gcc is installed? But IIUC it's only important to use the correct version to build the kernel. $ awk '{print $7}' /proc/version $ gcc -v I don't know if packages for proprietary graphics drivers include a pre-build module or if they build the module that fits to a kernel, it at least is common that for some distros pre-build modules for e.g. VBox are a packaged and a module only will fit to one kernel version, IOW to the distros default kernel. When I build kernels myself, usually all kernel versions are working. I guess there's an issue to use the Ubuntu package for Debian. For VBox I e.g. build the modules using dkms. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
