在OS X上安装GCC 4.7.1

问题描述

我试图在我的Mac上安装 GCC 4.7.1，因为我想更新 LLVM GCC 4.2在XCode中给出。

我已经下载了 GCC 4.7.1，并且将 gcc-4.7.1 文件夹位于〜/ Downloads> / code>中，然后我按照这里给出的指示：，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 
  

和



然后我写了



  make 
  

这一切都很顺利，直到我收到此消息

  rm -f stage_current 
比较阶段2和3 
警告：gcc / cc1-checksum.o不同
警告：gcc / cc1obj-checksum .o不同
警告：gc c / cc1plus-checksum.o不同
 Bootstrap比较失败！ 
 gcc / intl.o不同
 make [2]：*** [比较]错误1 
 make [1]：*** [stage3-bubble]错误2 
 make：*** [all] Error 2 
  

然后 make check 给我这个信息

  / bin / sh：line 0：cd：./fixincludes：No such文件或目录
 make [1]：*** [check-fixincludes]错误1 
 make：*** [do-check]错误2 
  

以及 make install 此信息

  / bin / sh /Users/fpiro07/Downloads/gcc-4.7.1/mkinstalldirs / usr / local / usr / local 
 / bin / sh：第0行：cd： ./fixincludes：没有这样的文件或目录
 make [1]：*** [install-fixincludes]错误1 
 make：*** [install]错误2 
  

如何解决这些问题并安装我的 GCC 4.7.1？

解决方案

安装并运行：

  $ sudo port selfupdate 
 $ sudo port install gcc47 
  

它会正确配置和安装gcc（4.7.2写作时间）和所有依赖关系。


I am trying to install GCC 4.7.1 on my Mac because I want to update the LLVM GCC 4.2 given in XCode.

I have downloaded GCC 4.7.1 and I've placed the gcc-4.7.1 folder in ~/Downloads, then I followed the instructions given here: http://gcc.gnu.org/install/ and I wrote

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

and the configuration does show problems.

Then I wrote

make

and it all goes well until I am given this message

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

Then the make check gives me this message

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

And the make install this messagge

/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

How can I fix these problems and have my GCC 4.7.1 installed?

解决方案

Install MacPorts and run:

$ sudo port selfupdate
$ sudo port install gcc47

It will take care of correctly configuring and installing gcc (4.7.2 at the time of writing) and all dependencies.
