我正在尝试GCC在我的 Mac 上安装 4.7.1，因为我想更新LLVM GCCXCode 中给出的 4.2。
我已经下载GCC了 4.7.1 并将gcc-4.7.1文件夹放在 中~/Downloads，然后我按照此处给出的说明进行操作：http: //gcc.gnu.org/install/我写了
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
一切都很顺利，直到我收到这条消息
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给我这个消息
/bin/sh: line 0: cd: ./fixincludes: No such file or directory
make[1]: *** [check-fixincludes] Error 1
make: *** [do-check] Error 2
而make install这个消息
/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
如何解决这些问题并安装我的GCC4.7.1？
