Dear developer, Hope this email finds you well. I'm trying to compile a native gcc (called it turtle-gcc for communication) from source using a cross-compiler gcc. Then I met the error: In file included from ../../../gcc-4.4.3/libgcc/../gcc/libgcc2.c:61: ../../../gcc-4.4.3/libgcc/../gcc/libgcc2.h:164: error: unable to emulate ‘XF’ ../../../gcc-4.4.3/libgcc/../gcc/libgcc2.h:165: error: unable to emulate ‘XC’ ../../../gcc-4.4.3/libgcc/../gcc/libgcc2.h:397: warning: conflicting types for built-in function ‘__divxc3’ ../../../gcc-4.4.3/libgcc/../gcc/libgcc2.h:398: warning: conflicting types for built-in function ‘__mulxc3’ make[2]: *** [Makefile:359: _muldi3.o] Error 1 make[2]: Leaving directory '/home/lind/lind_project/tests/applications/gcc-4.4.3_build/x86_64-nacl-linux/libgcc' make[1]: *** [Makefile:11488: all-target-libgcc] Error 2 make[1]: Leaving directory '/home/lind/lind_project/tests/applications/gcc-4.4.3_build' make: *** [Makefile:741: all] Error 2 Here is the configuration file I used: export CFLAGS="-ffloat-store" export CXXFLAGS="-ffloat-store" ../gcc-4.4.3/configure --enable-languages=c --disable-shared \ --disable-threads \ --enable-threads=single \ --disable-bootstarp \ --disable-decimal-float \ --disable-libatomic \ --disable-libcilkrts \ --disable-libgomp \ --disable-libitm \ --disable-libmudflap \ --disable-libquadmath \ --disable-libsanitizer \ --disable-libssp --disable-libstdcxx-pch \ --disable-libvtv \ --disable-lto \ --disable-lto-plugin \ --disable-multilib \ --disable-werror \ --with-bugurl="https://bugs.linaro.org/"; \ --build=x86_64-linux --host=x86_64-nacl-linux --target=x86_64-nacl-linux "$@" I have no idea what causes this error, could you please provide some instructions? Many thanks! Best, -- *Alice*
