builds are all done in a chroot from a clean system, this means that there is no kernel built (there are full kernel sources installed ) and that /lib/modules/ is completely empty. This environment fits where a user is when they do a stage3 install , necessarily so to get binaries done. make: Leaving directory `/var/tmp/portage/svgalib-1.9.17-r3/work/svgalib-1.9.17/threeDKit' make: Entering directory `/var/tmp/portage/svgalib-1.9.17-r3/work/svgalib-1.9.17/kernel/svgalib_helper' Makefile:10: *** INCLUDEDIR is not set up correctly. Stop. make: Leaving directory `/var/tmp/portage/svgalib-1.9.17-r3/work/svgalib-1.9.17/kernel/svgalib_helper' Basically the Makefile tries to use /lib/modules/`uname -r` to build the kernel helper. It would work far better and more reliably if this was repatched to always use /usr/src/linux (Makefile patch) This would also mean that theres some more form of consistency so you can actually build all modules for a kernel before you reboot into it.
the ebuild does this: make INCLUDEDIR="/usr/src/linux/include" -C kernel/svgalib_helper \ clean all || die "Failed to build kernel module!" then the patch is this: +ifndef INCLUDEDIR +INCLUDEDIR = /lib/modules/$(shell uname -r)/build/include +endif so i guess could you test to see if changing the '/lib/modules/$(shell uname -r)/build/include' to '/usr/src/linux/include' really makes a difference ? you get that error because of this bit of code: MODVER = $(shell grep CONFIG_MODVERSIONS $(INCLUDEDIR)/linux/autoconf.h 2>/dev/null) ifeq ($(MODVER),) @echo INCLUDEDIR is not set up correctly exit 1 endif which to me says the kernel isnt setup yet
true, the kernel isn't setup at that time, just installed. Frankly I'd want to be able to disable the kernel part of the library as we never package any kernel binaries, so packages that depend on it will be hopelessly broken for all time... For now, disabling svgalib (USE=-svga) and removing all packages that depend on it from the regressiontesting seems to be the only solution , and the one I have opted for. This however feels very suboptimal.
ok, i checked on gentoo-dev for perhaps splitting of kernel/userspace packages into their parts and was informed of the previous reason this did not happen ... dependency tracking hell svgalib needs a kernel that is semi-built in order to work
actually i lied, i'll just wrap the kernel module building with 'if [ ! `use build` ] ; then' i guess if there are any bugs past that you get to pick it up ;)
well, thats quite enough to make it work. thanks :)
`env USE=build emerge svgalib` and you should be set
