OS X cmake找不到PythonLibs 3.4 [英] OS X cmake can't find PythonLibs 3.4
问题描述
python和python3通过Homebrew安装在OS X Yosemite中，但是cmake无法找到PythonLibs 3，只有2:
python and python3 are installed in OS X Yosemite via Homebrew, but cmake fails to find PythonLibs 3, only 2:
CMakeLists.txt:
CMakeLists.txt:
set(Python_ADDITIONAL_VERSIONS 3.4)
FIND_PACKAGE(PythonInterp REQUIRED)
FIND_PACKAGE(PythonLibs 3.4 REQUIRED)
获取:
-- Found PythonInterp: /usr/local/bin/python3.4 (found suitable version "3.4.3", minimum required is "3.4")
-- Found PythonLibs: /usr/lib/libpython3.4.dylib (found version "2.7.6"
CMakeLists.txt:
CMakeLists.txt:
set(Python_ADDITIONAL_VERSIONS 3.4)
FIND_PACKAGE(PythonInterp 3.4 REQUIRED)
FIND_PACKAGE(PythonLibs 3.4 REQUIRED)
获取:
Could NOT find PythonLibs: Found unsuitable version "2.7.6", but required
is at least "3.4" (found PYTHON_LIBRARY-NOTFOUND)
然后我将其添加到cmake列表中:
Then I added this to cmake lists:
INCLUDE_DIRECTORIES(/usr/local/Cellar/python3/3.4.3/Frameworks/Python.framework/Versions/3.4/lib)
INCLUDE_DIRECTORIES(/usr/local/Cellar/python3/3.4.3/Frameworks/Python.framework/Versions/3.4/include/python3.4m)
，甚至将该目录复制到/usr/lib，然后得到:
and even copied that directories to /usr/lib, and then got:
Could NOT find PythonLibs: Found unsuitable version "2.7.6", but required
is at least "3.4" (found /usr/lib/libpython3.4.dylib)
看起来很奇怪.
推荐答案
您需要将路径添加到环境变量"LD_LIBRARY_PATH"中的库.这样，CMake将知道在哪里寻找它们.在多个python安装中或将其安装在非标准位置时，可能会发生这种情况.这应该可以解决:
You need to add the path to the libraries in your "LD_LIBRARY_PATH" environment variable. In this way, CMake will know where to look for them. This may happen with multiple python installations or when it is installed in a non standard location. This should solve it:
export LD_LIBRARY_PATH=/usr/local/Cellar/python3/3.4.3/Frameworks/Python.framework/Versions/3.4/lib:$LD_LIBRARY_PATH
CMake命令"INCLUDE_DIRECTORIES"仅用于标头(又名/usr/include).
The CMake command "INCLUDE_DIRECTORIES" is only for headers (aka. /usr/include).
->如果我的解决方案不起作用，请确保已安装python-devel:
