*very* briefly (i can supply more details later if necessary), i'm trying to install a patched NVIDIA driver (4363) under linux kernel 2.5.70 on RH 9, based on the following recipe: 0) build 2.5.70 kernel, modules, install, etc., reboot to 2.5.70 1) download latest NVIDIA geforce driver (4363) from nvidia 2) download 2.5.70 patch from www.minion.de 3) extract source tree from NVIDIA driver 4) apply patch, symlink Makefile 5) run "nvidia-installer", which eventually fails with ---------------------------- nvidia-installer log file '/var/log/nvidia-installer.log' creation time: Sat May 31 13:12:57 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. -> There appears to already be a driver installed on your system (version: 1.0- 4349). As part of installing this driver (version: 1.0-4363), the existing driver will be uninstalled. Are you sure you want to continue? ('no' will a bort installation) (Answer: Yes) -> 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. ERROR: The kernel header file '/lib/modules/2.5.70/build/include/linux/modversions.h' does not exist. The most likely reason for this is that the kernel header files in '/lib/modules/2.5.70/build/include' have not been configured. 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. -------------------------------- apparently, the installer *really* wants the kernel source file "include/linux/modversions.h", but there *is* no such file in the 2.5.70 source tree. there *is* an include/config/modversions.h, but i don't know why i'm running into this. is there a kernel config option i forgot (i added all module options). can anyone explain where i should find the missing modversions.h file? thanks. rday
