O=build and -j 1 the build fails: # # gcc ... -I../arch/powerpc/boot -c -o arch/powerpc/boot/serial.o arch/powerpc/boot/serial.c # gcc: error: arch/powerpc/boot/serial.c: No such file or directory # # Why this is only happening with -j 1 is not clear, when building with # -j greater than 1 somehow we decide to look for serial.c in the src # tree (../), eg: # # gcc -I../arch/powerpc/boot -c -o arch/powerpc/boot/serial.o ../arch/powerpc/boot/serial.c # # Regardless we shouldn't be specifying a dependency on serial.c in the # build tree, we want to add a dependency to the version in $(srctree) # so fix the rule to say that. # # Fixes: 5e9dcb6188a4 ("powerpc/boot: Expose Kconfig symbols to wrapper") # Tested-by: Daniel Axtens <dja@axtens.net> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 e41b93a6be57e26a4a123345f826a6ac3a213551 # < make -s -j 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_corenet_basic_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- corenet_basic_defconfig # make -s -j 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_corenet_basic_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:341:21: note: 'pdeo' was declared here Completed OK # rm -rf /kisskb/build/powerpc-fixes_corenet_basic_defconfig_powerpc # Build took: 0:00:35.108349
