From b925dbfe3c59b637666670a60473a15d29e0a7a7 Mon Sep 17 00:00:00 2001 From: Josh Hunt Date: Thu, 12 Feb 2009 10:16:05 -0800 Subject: kbuild: fix 'make rpm' when CONFIG_LOCALVERSION_AUTO=y and using SCM tree Running 'make rpm' fails when CONFIG_LOCALVERSION_AUTO=y and using a kernel source tree under SCM. This is due to KERNELRELEASE being different when the initial make is run and when make is run from rpmbuild. mkspec creates kernel.spec using KERNELRELEASE: echo "%files" echo '%defattr (-, root, root)' echo "%dir /lib/modules" echo "/lib/modules/$KERNELRELEASE" echo "/lib/firmware" echo "/boot/*" echo "" When CONFIG_LOCALVERSION_AUTO=y scripts/setlocalversion is called and grabs any additional version info from SCM. Next, the srctree is tarred up and SCM information is excluded. rpmbuild reruns make and in the process generates a new include/config/kernel.release and thus a new KERNELRELEASE. However this time the SCM information is gone so KERNELRELEASE no longer has the additional version information. When "make modules_install" runs, it uses the new KERNELRELEASE value to determine where to install the modules. This conflicts with where the spec file assumes they are going because of the mis-matching KERNELRELEASE versions. + INSTALL_MOD_PATH=/var/tmp/kernel-2.6.29rc4tip01479g5d85422-root + make -j16 modules_install INSTALL crypto/aead.ko INSTALL crypto/cbc.ko INSTALL crypto/chainiv.ko INSTALL crypto/crc32c.ko INSTALL crypto/crypto_algapi.ko INSTALL crypto/crypto_blkcipher.ko INSTALL crypto/crypto_hash.ko INSTALL crypto/cryptomgr.ko INSTALL crypto/ecb.ko INSTALL crypto/eseqiv.ko INSTALL crypto/krng.ko INSTALL crypto/md5.ko INSTALL crypto/pcbc.ko INSTALL crypto/rng.ko INSTALL drivers/block/cciss.ko INSTALL drivers/hid/hid-dummy.ko INSTALL drivers/scsi/iscsi_tcp.ko INSTALL drivers/scsi/libiscsi.ko INSTALL drivers/scsi/libiscsi_tcp.ko INSTALL drivers/scsi/scsi_transport_iscsi.ko INSTALL drivers/scsi/scsi_wait_scan.ko INSTALL fs/lockd/lockd.ko INSTALL fs/nfs/nfs.ko INSTALL fs/nfsd/nfsd.ko INSTALL lib/libcrc32c.ko INSTALL net/sunrpc/sunrpc.ko DEPMOD 2.6.29-rc4-tip + cp arch/x86/boot/bzImage /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/vmlinuz-2.6.29-rc4-tip-01479-g5d85422 + cp System.map /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/System.map-2.6.29-rc4-tip-01479-g5d85422 + cp .config /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/config-2.6.29-rc4-tip-01479-g5d85422 + cp vmlinux vmlinux.orig + bzip2 -9 vmlinux + mv vmlinux.bz2 /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/boot/vmlinux-2.6.29-rc4-tip-01479-g5d85422.bz2 + mv vmlinux.orig vmlinux + /usr/lib/rpm/brp-compress Processing files: kernel-2.6.29rc4tip01479g5d85422-2 error: File not found: /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/lib/modules/2.6.29-rc4-tip-01479-g5d85422 RPM build errors: File not found: /var/tmp/kernel-2.6.29rc4tip01479g5d85422-root/lib/modules/2.6.29-rc4-tip-01479-g5d85422 make[1]: *** [rpm] Error 1 make: *** [rpm] Error 2 I have tested this patch on git -tip, Linus' git tree, and the kernel.org tar files, both with and without CONFIG_LOCALVERSION_AUTO=y.
