| |
In the 2.4 kernel, 'make symlinks' created the symlinks needed to use the kernel tree's headers for building a gcc/glibc toolchain.
In the 2.6 kernel, you can do the same thing with 'include include/asm'. Unless you're trying to build arm or cris, or maybe others, in which case you also need 'include/asm-$(ARCH)/.arch'.
That's fine, but it means that a script (like crosstool) or a book (like LFS) that's trying to build a gcc/glibc toolchain for both 2.4 and 2.6 ends up with a section like
case "$KERNEL_VERSION.$KERNEL_PATCHLEVEL.x" in 2.2.x|2.4.x) make ARCH=$ARCH symlinks include/linux/version.h ;; 2.6.x) make ARCH=$ARCH include/asm include/linux/version.h case $ARCH in arm*|cris*) make ARCH=$ARCH include/asm-$ARCH/.arch ;; esac ;; *) abort "Unsupported kernel version $KERNEL_VERSION.$KERNEL_PATCHLEVEL" esac
which is a bit ugly. It'd be nice if 'make symlinks' did the neccesary stuff in 2.6, too. Think a patch to do that would be accepted? - Dan
