Hello, I'm trying to compile GCC 4.4.3 for the powerpc-wrs-vxworks target, in an cygwin environment. I was able to compile binutils-2.20.1 fine for the same target. Here's the options I'm specifying: bash-3.2# ../gcc-4.4.3/configure --target=powerpc-wrs-vxworks --with-included-gettext --with-gnu-as --with-gnu-ld --with-headers=`cygpath -aup $WIND_BASE`/target/h --with-included-gettext --enable-languages=c,c++ -v To me, it looks like an incorrect invocation of the C preprocessor, but I'm looking for more guidance here (either a workaround, or what I should change). I'm attaching config.log. I've tried gcc-core distribution as well, and it fails with the exact same error. The compilation fails with the following error: checking for powerpc-wrs-vxworks-gcc... /cygdrive/c/Downloads/build-gcc/./gcc/xgcc -B/cygdrive/c/Downloads/build-gcc/./g cc/ -B/usr/local/powerpc-wrs-vxworks/bin/ -B/usr/local/powerpc-wrs-vxworks/lib/ -isystem /usr/local/powerpc-wrs-vxworks/ include -isystem /usr/local/powerpc-wrs-vxworks/sys-include checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether /cygdrive/c/Downloads/build-gcc/./gcc/xgcc -B/cygdrive/c/Downloads/build-gcc/./gcc/ -B/usr/local/powerp c-wrs-vxworks/bin/ -B/usr/local/powerpc-wrs-vxworks/lib/ -isystem /usr/local/powerpc-wrs-vxworks/include -isystem /usr/l ocal/powerpc-wrs-vxworks/sys-include accepts -g... yes checking for /cygdrive/c/Downloads/build-gcc/./gcc/xgcc -B/cygdrive/c/Downloads/build-gcc/./gcc/ -B/usr/local/powerpc-wr s-vxworks/bin/ -B/usr/local/powerpc-wrs-vxworks/lib/ -isystem /usr/local/powerpc-wrs-vxworks/include -isystem /usr/local /powerpc-wrs-vxworks/sys-include option to accept ANSI C... none needed checking how to run the C preprocessor... /lib/cpp configure: error: in `/cygdrive/c/Downloads/build-gcc/powerpc-wrs-vxworks/libgcc': configure: error: C preprocessor "/lib/cpp" fails sanity check See `config.log' for more details. make[1]: *** [configure-target-libgcc] Error 1 make[1]: Leaving directory `/cygdrive/c/Downloads/build-gcc' make: *** [all] Error 2
