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/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux-gcc --version # < git log --format=%s --max-count=1 e41b93a6be57e26a4a123345f826a6ac3a213551 # < make -s -j 8 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- mmu_defconfig # make -s -j 8 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized] if (ret == -EOPNOTSUPP) ^ Kernel: arch/microblaze/boot/linux.bin is ready (#1) Completed OK # rm -rf /kisskb/build/powerpc-fixes_mmu_defconfig_microblaze # Build took: 0:01:02.355467
