i upgraded to the latest kernel rpm with fou4s and i had to reboot and i see shadowns around applications i tried installing latest nvidia driver but it fails with this error any way to get around this, my problem seems like a driver issue nvidia-installer log file '/var/log/nvidia-installer.log' creation time: Fri Aug 22 19:10:14 2003 option status: license pre-accepted : false update : false force update : false expert : false uninstall : false driver info : false no precompiled interface: false no ncurses color : false query latest driver ver : false OpenGL header files : false no questions : false silent : false XFree86 install prefix : /usr/X11R6 OpenGL install prefix : /usr Installer install prefix: /usr kernel include path : (not specified) kernel install path : (not specified) proc mount point : /proc ui : (not specified) tmpdir : /tmp ftp site : ftp://download.nvidia.com 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: Yes) -> No matching precompiled kernel interface was found on the NVIDIA ftp site; this means that the installer will need to compile a kernel interface for your kernel. -> Kernel include path: '/lib/modules/2.4.20-4GB/build/include' -> Cleaning kernel module build directory. executing: 'cd ./usr/src/nv; make clean'... rm -f nv.o os-agp.o os-interface.o os-registry.o nv-linux.o nv_compiler.h * .d NVdriver nvidia.o -> Building kernel module: executing: 'cd ./usr/src/nv; make nvidia.o SYSINCLUDE=/lib/modules/2.4.20-4G B/build/include'... You appear to be compiling the NVIDIA kernel module with a compiler different from the one that was used to compile the running kernel. This may be perfectly fine, but there are cases where this can lead to unexpected behaviour and system crashes. If you know what you are doing and want to override this check, you can do so by setting IGNORE_CC_MISMATCH. In any other case, set the CC environment variable to the name of the compiler that was used to compile the kernel. [1;31m*** Failed cc sanity check. Bailing out! *** [0mmake: *** [gcc-check] Error 1 -> Error. ERROR: Unable to build the NVIDIA kernel module. 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.
