在OS X上安装GCC 4.7.1

Question

我想在Mac上安装GCC 4.7.1，因为我想更新XCode中提供的LLVM GCC 4.2。

我已经下载了GCC 4.7.1，并将gcc-4.7.1文件夹放置在~/Downloads中，然后按照此处给出的说明进行了操作：http://gcc.gnu.org/install/，然后写了]]

cd ~/Desktop
mkdir objdir
cd objdir
~/Downloads/gcc-4.7.1/configure --with-gmp=/usr/local/include --with-mpfr=/usr/local/include --with-mpc=/usr/local/include
并且配置确实显示了问题。

然后我写了

make
一切顺利，直到收到此消息

rm -f stage_current
Comparing stages 2 and 3
warning: gcc/cc1-checksum.o differs
warning: gcc/cc1obj-checksum.o differs
warning: gcc/cc1plus-checksum.o differs
  Bootstrap comparison failure!
gcc/intl.o differs
make[2]: *** [compare] Error 1
make[1]: *** [stage3-bubble] Error 2
make: *** [all] Error 2
然后make check给我此消息

/bin/sh: line 0: cd: ./fixincludes: No such file or directory
make[1]: *** [check-fixincludes] Error 1
make: *** [do-check] Error 2
[make install此消息

/bin/sh /Users/fpiro07/Downloads/gcc-4.7.1/mkinstalldirs /usr/local /usr/local
/bin/sh: line 0: cd: ./fixincludes: No such file or directory
make[1]: *** [install-fixincludes] Error 1
make: *** [install] Error 2
