The binrpm-pkg target (binary RPM only) fails when called with KBUILD_OUTPUT set. This patch makes it work. For the rpm-pkg target (source + binary RPM), building with KBUILD_OUTPUT set is not possible and also not needed as the actual build is done in a temporary directory anyway, so check that KBUILD_OUTPUT is not set in that case to avoid later errors. Signed-off-by: Frans Pop <elendil@planet.nl> --- I ran into this while trying if I could build an RPM kernel package on my Debian notebook :-) The patch has been tested by doing three builds: - make -j4 rpm-pkg - make -j4 binrpm-pkg - KBUILD_OUTPUT=../builds/amd64 make -j4 binrpm-pkg For all three the contents of the resulting binary RPM package was identical (and looked correct); the source RPM package from the first build looked sane. A 'KBUILD_OUTPUT=../builds/amd64 make -j4 rpm-pkg' fails as intended. One open issue is that the following commands should IIUC be identical, but the second one does not work: - KBUILD_OUTPUT=../builds/amd64 make -j4 binrpm-pkg - make -j4 O=../builds/amd64 binrpm-pkg AFAICT the root Makefile is supposed to set KBUILD_OUTPUT based on O=, but that is not visible when the lines within the binrpm-pkg target are executed. My make foo was not strong enough to debug this. Sam, do you know?
