在 Yosemite 上安装 cunn for torch 失败并出现错误的对象错误。 

 -- Install configuration: "Release"
-- Installing: /usr/local/lib/luarocks/rocks/cunn/scm-1/lib/libcunn.so

Updating manifest for /usr/local/lib/luarocks/rocks
cunn scm-1 is now built and installed in /usr/local/ (license: BSD)

在线搜索显示这与库损坏或 install_name_tool 的更新有关。我将 XCode(6.1) 中的 install_name_tool 替换为 /usr/bin ，但仍然出现同样的错误。下面是一些诊断

$ ls -l $(which install_name_tool)
-rwxr-xr-x  1 root  admin  14192 Nov  8 11:25 /opt/local/bin/install_name_tool

$ otool -L /usr/bin/install_name_tool
/usr/bin/install_name_tool:
    /usr/lib/libxcselect.dylib (compatibility version 1.0.0, current version 1.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)


$ pkgutil --file-info /usr/bin/install_name_tool
volume: /
path: /usr/bin/install_name_tool

pkgid: com.apple.pkg.Essentials

install-time: 1413599255

我需要这个才能工作，以便我可以将 CUDA 与 Torch 一起使用，我已经花了几个小时在上面，请帮忙。

我有同样的问题，我通过libcunn.so本地构建解决了它。运行以下命令：

git clone https://github.com/torch/cunn.git
ls cunn
cmake -E make_directory build
cd build/
cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH="/usr/local/bin/.." -DCMAKE_INSTALL_PREFIX="/usr/local/lib/luarocks/rocks/cunn/scm-1" && make

那么你应该有

Linking CXX shared module libcunn.so

然后只需将库复制到目标文件夹：

cp libcunn.so /usr/local/lib/lua/5.1/libcunn.so
