Hmm... for me, it is not toolchain's bug, it is a feature issue in gcc old version, and in newer version it is OK (in my memory, after gcc-4.7, it is OK). In our "arch/*", really contents some another architectures which already use "-D__linux__" in their "Makefile". :-) Thanks. > >> The related error: >> >> CC [M] fs/coda/psdev.o >> In file included from include/linux/coda.h:64, >> from fs/coda/psdev.c:45: >> include/uapi/linux/coda.h:221: error: expected specifier-qualifier-list >> before 'u_quad_t' >> >> The related toolchain version (which only download, not re-compile): >> >> [root@gchen linux-next]# >> /upstream/toolchain/download/avr32-gnu-toolchain-linux_x86/bin/avr32-gcc -v >> Using built-in specs. >> Target: avr32 >> Configured with: >> /data2/home/toolsbuild/jenkins-knuth/workspace/avr32-gnu-toolchain/src/gcc/configure >> --target=avr32 --host=i686-pc-linux-gnu --build=x86_64-pc-linux-gnu >> --prefix=/home/toolsbuild/jenkins-knuth/workspace/avr32-gnu-toolchain/avr32-gnu-toolchain-linux_x86 >> --enable-languages=c,c++ --disable-nls --disable-libssp >> --disable-libstdcxx-pch --with-dwarf2 --enable-version-specific-runtime-libs >> --disable-shared --enable-doc >> --with-mpfr-lib=/home/toolsbuild/jenkins-knuth/workspace/avr32-gnu-toolchain/avr32-gnu-toolchain-linux_x86/lib >> >> --with-mpfr-include=/home/toolsbuild/jenkins-knuth/workspace/avr32-gnu-toolchain/avr32-gnu-toolchain-linux_x86/include >> >> --with-gmp=/home/toolsbuild/jenkins-knuth/workspace/avr32-gnu-toolchain/avr32-gnu-toolchain-linux_x86 >> >> --with-mpc=/home/toolsbuild/jenkins-knuth/workspace/avr32-gnu-toolchain/avr32-gnu-toolchain-linux_x86 >> --enable-__cxa_atexit --disable-shared --with-newlib >> --with-pkgversion=AVR_32_bit_GNU_Toolchain_3.4.2_435 --with-bugurl=http:/ / www >> .atmel.com/avr >> Thread model: single >> gcc version 4.4.7 (AVR_32_bit_GNU_Toolchain_3.4.2_435) >> >> >> Signed-off-by: Chen Gang <[email protected]> >> --- >> arch/avr32/Makefile | 2 +- >> 1 file changed, 1 insertion(+), 1 deletion(-) >> >> diff --git a/arch/avr32/Makefile b/arch/avr32/Makefile >> index 22fb665..dba48a5 100644 >> --- a/arch/avr32/Makefile >> +++ b/arch/avr32/Makefile >> @@ -11,7 +11,7 @@ all: uImage vmlinux.elf >> >> KBUILD_DEFCONFIG := atstk1002_defconfig >> >> -KBUILD_CFLAGS += -pipe -fno-builtin -mno-pic >> +KBUILD_CFLAGS += -pipe -fno-builtin -mno-pic -D__linux__ >> KBUILD_AFLAGS += -mrelax -mno-pic >> KBUILD_CFLAGS_MODULE += -mno-relax >> LDFLAGS_vmlinux += --relax >> -- >> 1.7.11.7 >> -- >> To unsubscribe from this list: send the line "unsubscribe linux-kernel" in >> the body of a message to [email protected] >> More majordomo info at http://vger.kernel.org/majordomo-info.html >> Please read the FAQ at http://www.tux.org/lkml/ > > > -- Chen Gang Open, share and attitude like air, water and life which God blessed -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
