Hi, I'm trying to build a cross-toolchain with x86_64 target. I've successfully compiled binutils-2.22, gmp-5.0.4, mpc-0.9 and mpfr-3.1.0, however I'm stuck with gcc-4.7.0. I configured it with ../gcc-4.7.0/configure --prefix=/cross-tools --build=$HOST --host=$HOST --target=$TARGET --with-sysroot=/mnt/root --disable-shared --disable-nls --with-mpfr=/cross-tools --with-gmp=/cross-tools --without-ppl --without-cloog --disable-decimal-float --disable-libgomp --disable-libmudflap --disable-libssp --disable-threads --disable-multilib --enable-languages=c --without-headers and got the following error: make[2]: Entering directory `/mnt/root/sources/gcc-build/x86_64-cerebro-linux-gnu/libgcc' # If this is the top-level multilib, build all the other # multilibs. /mnt/root/sources/gcc-build/./gcc/xgcc -B/mnt/root/sources/gcc-build/./gcc/ -B/cross-tools/x86_64-cerebro-linux-gnu/bin/ -B/cross-tools/x86_64-cerebro-linux-gnu/lib/ -isystem /cross-tools/x86_64-cerebro-linux-gnu/include -isystem /cross-tools/x86_64-cerebro-linux-gnu/sys-include -g -O2 -O2 -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fpic -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector -fpic -I. -I. -I../.././gcc -I../../../gcc-4.7.0/libgcc -I../../../gcc-4.7.0/libgcc/. -I../../../gcc-4.7.0/libgcc/../gcc -I../../../gcc-4.7.0/libgcc/../include -DHAVE_CC_TLS -DUSE_TLS -o _muldi3.o -MT _muldi3.o -MD -MP -MF _muldi3.dep -DL_muldi3 -c ../../../gcc-4.7.0/libgcc/libgcc2.c In file included from ../../../gcc-4.7.0/libgcc/libgcc2.c:29:0: ../../../gcc-4.7.0/libgcc/../gcc/tsystem.h:88:19: fatal error: stdio.h: No such file or directory compilation terminated. make[2]: *** [_muldi3.o] Error 1 make[2]: Leaving directory `/mnt/root/sources/gcc-build/x86_64-cerebro-linux-gnu/libgcc' make[1]: *** [all-target-libgcc] Error 2 make[1]: Leaving directory `/mnt/root/sources/gcc-build' As I understand --without-headers option should prevent compiler from looking for libc headers. Why therefore it is looking for (and missing) stdio.h? Best regards, Adam Mobile: +48 695 537 163 Skype: amgo100
