But at this point I just want to have a # working system so that I can continue the merge window work tomorrow. # # Cc: Takashi Iwai <tiwai@suse.de> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 4b820e167bf6f410ace479d8df5b15a574000e75 # < make -s -j 48 ARCH=arm O=/kisskb/build/linus_efm32_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- efm32_defconfig * * Can't find default configuration "arch/arm/configs/efm32_defconfig"! * make[2]: * [/kisskb/src/scripts/kconfig/Makefile:94: efm32_defconfig] Error 1 make[1]: * [/kisskb/src/Makefile:614: efm32_defconfig] Error 2 make: *** [Makefile:215: __sub-make] Error 2 Command 'make -s -j 48 ARCH=arm O=/kisskb/build/linus_efm32_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- efm32_defconfig' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_efm32_defconfig_arm-gcc4.9 # Build took: 0:00:01.867224
