  gcc 搜索路径:

  1、 gcc -print-search-dirs     

install: /usr/lib/gcc/i686-w64-mingw32/4.6/

programs: =/usr/lib/gcc/i686-w64-mingw32/4.6/:/usr/lib/gcc/i686-w64-mingw32/4.6/:/usr/lib/gcc/i686-w64-mingw32/:/usr/lib/gcc/i686-w64-mingw32/4.6/:/usr/lib/gcc/i686-w64-mingw32/:/usr/lib/gcc/i686-w64-mingw32/4.6/../../../../i686-w64-mingw32/bin/i686-w64-mingw32/4.6/:/usr/lib/gcc/i686-w64-mingw32/4.6/../../../../i686-w64-mingw32/bin/

libraries: =/usr/lib/gcc/i686-w64-mingw32/4.6/:/usr/lib/gcc/i686-w64-mingw32/4.6/../../../../i686-w64-mingw32/lib/i686-w64-mingw32/4.6/:/usr/lib/gcc/i686-w64-mingw32/4.6/../../../../i686-w64-mingw32/lib/../lib/:/usr/lib/gcc/i686-w64-mingw32/4.6/../../../../i686-w64-mingw32/lib/

--with-sysroot=DIR将 dir 看作目标系统的根目录。目标系统的头文件、库文件、运行时对象都将被限定在其中。
