http://www.linuxquestions.org/questions/linux-software-2/configure-error-c-preprocessor-lib-cpp-fails-sanity-check-124961/ I know this shouldn't be right. gcc was already installed on my machine but I still got: C++ preprocessor "/lib/cpp" fails sanity check I looked at config.log and it said something like: cc1plus command not found
i found cc1 /usr/lib/gcc/i586-mandrake-linux-gnu/3.4.1/cc1 so I linked it in /usr/bin ln -s /usr/lib/gcc/i586-mandrake-linux-gnu/3.4.1/cc1 cc1plus
voila: all working
