Hello, I've tried to build GCC 4.8.1 numerous times without any luck. Build, host, and target system: i686-pc-mingw32. I'm using MinGW Shell, gcc -v 4.6.2 ; g++ -v 4.7.2 Configure goes fine, then building starts: it builds all required libraries and other built-in libraries, and ./gcc folder. Then it starts to build ./i686-pc-mingw32/libgcc folder, and that's when it crashes. Configure: ../gcc-*/configure --enable-languages=c,c++ Make: make Every time I got to this point, shell showed following error: checking how to run the C preprocessor... /lib/cpp configure: error: in `/y/Downloads/gcc481d/i686-pc-mingw32/libgcc` configure: error: C preprocessor "/lib/cpp" fails sanity check See `config.log` for more details. make[2]: *** [configure-stage1-target-libgcc] Error1 make[2]: Leaving directory /y/Downloads/gcc481d make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory /y/Downloads/gcc481d make: *** [all] Error 2 I've attached config.log. Any ideas how to fix this? Thanks.
