I added the --disable-multilib --with-sysroot,like: ../gcc-4.3.2/configure --target=arm-linux --prefix=/home/yg/arm/usr --with-sysroot=/home/yg/arm/usr/ --disable-multilib But the problem still there: -fvisibility=hidden -DHIDE_EXPORTS <command-line>: warning: missing whitespace after the macro name In file included from /home/yg/arm/usr/arm-linux/sys-include/features.h:354, from /home/yg/arm/usr/arm-linux/sys-include/stdio.h:28, from ../../../gcc-4.3.2/libgcc/../gcc/tsystem.h:90, from ../../../gcc-4.3.2/libgcc/../gcc/libgcc2.c:33: /home/yg/arm/usr/arm-linux/sys-include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory make[2]: *** [_muldi3.o] Error 1 make[2]: Leaving directory `/home/yg/arm/achieve/gcc/arm-linux/libgcc' make[1]: *** [all-target-libgcc] Error 2 make[1]: Leaving directory `/home/yg/arm/achieve/gcc' make: *** [all] Error 2 I enter the /home/yg/usr/arm-linux/sys-include/gnu/,found only: stubs-64.h stubs.h so there is no stubs-32.h.My computer is x86_64,and the arm is 32 bit system,maybe this is the problem.Or I should recomplie glibc with more opinions.I'm confused.
