Mac Rmagick won't install with Xcode 4.2
提问by Danny Hiemstra
I just got a new macbook pro and trying to setup my dev environment. I downloaded xcode 4.2 from the app store and installed it, after this i installed homebrew and RVM. ImageMagick, readline, ruby 1.9.3-head all installed perfectly until i ran bundle update which tried to install rmagick.
我刚买了一台新的 macbook pro 并尝试设置我的开发环境。我从应用商店下载了 xcode 4.2 并安装了它，之后我安装了自制软件和 RVM。ImageMagick、readline、ruby 1.9.3-head 全部安装完美，直到我运行 bundle update 试图安装 rmagick。
After a long long time investigating i come down to the conclusion that it can't find libgomp.
经过长时间的调查，我得出的结论是它找不到 libgomp。
The output is from gem install rmagickis:
输出来自gem install rmagick：
$ gem install rmagick

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

You have to install development tools first.
Here is my mkmf.log file:
这是我的 mkmf.log 文件：

checked program was:
/* begin */
1: #include "ruby.h"
2:
3: int main() {return 0;}
/* end */
Now i assumed here that something was wrong with xcode i tried several things:
现在我在这里假设 xcode 有问题我尝试了几件事：
- Reinstall xcode
- Remove imagemagick and reinstalled it including other libraries like jpg, libpng etc
- Installed older version of imagemagick
- Removed .rvm and reinstalled a fresh copy of ruby
- 重新安装 xcode
- 删除 imagemagick 并重新安装它，包括其他库，如 jpg、libpng 等
- 安装旧版本的 imagemagick
- 删除 .rvm 并重新安装 ruby 的新副本
I have no clue what's left for me to try, could anyone help to push me in the good direction?
我不知道还有什么可以尝试的，有人可以帮助我朝着好的方向发展吗？

I tried to download and install 4.1 for lion and this didn't even install (without a proper error message). Now a colleague gave me this great link to GCC for Mac which worked like a charm: https://github.com/kennethreitz/osx-gcc-installer
我尝试为 Lion 下载并安装 4.1 并且这甚至没有安装（没有正确的错误消息）。现在，一位同事给了我这个很棒的 GCC for Mac 链接，它就像一个魅力：https: //github.com/kennethreitz/osx-gcc-installer
Don't forget to download the v2 if you run on > 10.7.0
如果您在 > 10.7.0 上运行，请不要忘记下载 v2

I tried your solution (full of hope) but It did not work for me unfortunately. Finally I managed to make it work by reinstalling imagemagick without openmp support (this is the library responsible for lgomp)
我尝试了您的解决方案（充满希望），但不幸的是它对我不起作用。最后我设法通过在没有 openmp 支持的情况下重新安装 imagemagick 使其工作（这是负责 lgomp 的库）
using Homebrew:
使用自制软件：
brew install imagemagick --disable-openmp
then rmagick installed without any problems.
然后 rmagick 安装没有任何问题。

For people who want source installation, you can download the source code repository and issue this command in the imagemagick source code directory.
想要源码安装的可以下载源码仓库，在imagemagick源码目录下发出这个命令。
./configure --disable-openmp
./configure --disable-openmp
It will work similar to the brew version above but with source code compilation instead.
它将与上面的 brew 版本类似，但使用源代码编译。

I ran into this problem using Macports but there are no guides so I'll add one here:
