Build and install Brew apps that are x86
After I have done this:
brew install git
I do this:
which git
which returns:
/usr/local/bin/git
I then do this:
file /usr/local/bin/git
which returns:
/usr/local/bin/git: Mach-O executable i386
I need brew to install as x86_64.
How can I force brew to build and install my apps as x86_64?
brew --config
Returns this:
HOMEBREW_VERSION: 0.9
HEAD: 1c64a6624ed83ef17af6e98638b8165400e9e908
HOMEBREW_PREFIX: /usr/local
HOMEBREW_CELLAR: /usr/local/Cellar
CPU: quad-core 64-bit sandybridge
OS X: 10.7.4
Kernel Architecture: x86_64
Xcode: 4.3.2
GCC-4.0: N/A
GCC-4.2: N/A
LLVM: build 2336
Clang: 3.1 build 318
MacPorts or Fink? false
X11: /usr/X11
System Ruby: 1.8.7-357
Which Perl: /usr/bin/perl
Which Python: /usr/bin/python
Which Ruby: /Users/tdewell/.rvm/rubies/ruby-1.9.3-p194/bin/ruby
Update: adding brew --env
$ brew --env
CC: /usr/bin/xcrun gcc-4.2 => /Developer/usr/bin/gcc-4.2
CXX: /usr/bin/xcrun g++-4.2 => /Developer/usr/bin/g++-4.2
LD: /usr/bin/xcrun gcc-4.2 => /Developer/usr/bin/gcc-4.2
CFLAGS: -Os -w -pipe -march=core2 -msse4
CXXFLAGS: -Os -w -pipe -march=core2 -msse4
MAKEFLAGS: -j4
This has been solved.
I installed Xcode 4.3.2 via the App Store and installed the Command Line Tools, but I had an existing Xcode 3.1 installed from years ago. I Googled around and found these commands:
sudo /Developer/Library/uninstall-devtools –mode=all
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
That cured my problem and after I did that the compilers changed for brew:
$ brew --env
CC: /usr/bin/clang
CXX: /usr/bin/clang++ => /usr/bin/clang
LD: /usr/bin/clang
CFLAGS: -Os -w -pipe -march=native -Qunused-arguments
CXXFLAGS: -Os -w -pipe -march=native -Qunused-arguments
MAKEFLAGS: -j4
brew installs are much better now:
$ which git
/usr/local/bin/git
$ file /usr/local/bin/git
/usr/local/bin/git: Mach-O 64-bit executable x86_64
尝试
xcode-select --install
