构建和安装x86_64而不是i386的Brew应用程序？

Question

我这样做之后:

brew安装git

我这样做:

哪个git

返回:

在/ usr/local/bin目录/混帐

然后我这样做:

文件/ usr/local/bin/git

返回:

/ usr/local/bin/git:Mach-O可执行文件i386

我需要brew安装为x86_64.

如何强制brew来构建和安装我的应用程序x86_64？

brew --config

返回此:

HOMEBREW_VERSION: 0.9
HEAD: 1c64a6624ed83ef17af6e98638b8165400e9e908
HOMEBREW_PREFIX: /usr/local

更新:添加brew --env

$ brew --env

CXX: /usr/bin/xcrun g++-4.2 => /Developer/usr/bin/g++-4.2

CFLAGS: -Os -w -pipe -march=core2 -msse4
CXXFLAGS: -Os -w -pipe -march=core2 -msse4
MAKEFLAGS: -j4

Answer 1

这已经解决了。

我通过 App Store 安装了 Xcode 4.3.2 并安装了命令行工具，但我已经安装了多年前的 Xcode 3.1。我用谷歌搜索了一下，发现了这些命令：

\n\n

sudo /Developer/Library/uninstall-devtools \xe2\x80\x93mode=all\n\nsudo xcode-select -switch /Applications/Xcode.app/Contents/Developer\n

\n\n

这解决了我的问题，在我这样做之后，编译器更改为brew：

\n\n

$ brew --env\nCC: /usr/bin/clang\nCXX: /usr/bin/clang++ => /usr/bin/clang\nLD: /usr/bin/clang\nCFLAGS: -Os -w -pipe -march=native -Qunused-arguments\nCXXFLAGS: -Os -w -pipe -march=native -Qunused-arguments\nMAKEFLAGS: -j4\n

\n\n

现在，brew 安装好多了：

\n\n

$ which git\n/usr/local/bin/git\n\n$ file /usr/local/bin/git\n/usr/local/bin/git: Mach-O 64-bit executable x86_64\n

\n
