Linus Torvalds himself has said that "the Debian way" of shipping kernel headers is the only correct way. Several times, in fact. But for some reason a lot of people seem to ignore him on this topic. You have to compile user-land programs that use the systems C library against the same header files the C library was compiled against, otherwise you can get serious versioning problems. So pointing /usr/include/linux to just any kernels includes is something you shouldn't ever do. It has to point to the includes that were used to compile the C library. That's why Debian ships a copy of those files with libc6-dev. >For example if you are running Debian (potato) your /usr/include/linux >and /usr/include/asm contain the files for Linux 2.2.16 and let's say you >are running Linux 2.4.2 on this, if you try and compile any thing >kernel dependant, you're going to get a bunch of undefines - >try compiling any device driver on Debian!. Nonsense, just use -I/usr/src/linux/include and you're set. You'll have to do that anyway if for example you want to include say <net/llc.h> - it doesn't exist under /usr/include/net and never will because even on systems that link /usr/include/linux -> /usr/src/linux/include/linux the systems /usr/include/net is something completely different from the kernels /usr/src/linux/include/net. It's a shame that so many people are misinformed and spread that misinformation like gospel. Mike. -- I live the way I type; fast, with a lot of mistakes.
