找到带有蟒蛇cmake前缀的Boost-python3

2022-06-06 00:00:00 anaconda caffe cmake c++ boost

DLDR如何将cmake指向Boost-python3库？Cmake不会自动检测到它。

我正在尝试使用提供的cmake为Python3.6生成caffe。

我的系统规格：

  • Python 3.6.5，蟒蛇定制(64位)
  • Mac OS 10.13.6
  • 无CUDA

我已使用BREW安装Boost，例如

brew install boost boost-python3

我可以使用find / -name libboost* 2>/dev/null查看Boost库。它们出现在三个目录中

  1. /usr/local/Cellar/boost/1.67.0_1/lib/
  2. /usr/local/lib/->符号链接到上面
  3. Boost-python3位于/usr/local/Cellar/boost-python/1.67.0/lib/

如果我运行cmake -DCMAKE_PREFIX_PATH=<anaconda_env_path> -D python_version=3，我会在输出的顶部看到以下内容

-- Boost version: 1.67.0
-- Found the following Boost libraries:
--   system
--   thread
--   filesystem
--   chrono
--   date_time
--   atomic

但再往下，我也得到了

与Cmake doesn't find Boost类似，我尝试添加

-DBOOST_ROOT=/usr/local/Cellar/boost/1.67.0_1/lib/ -DBoost_DEBUG=1

添加到cmake命令。在生成的输出中，以下命令将重复以下命令三次：Boost_python-py365、Boost_python-py36、Boost_python-py3和Boost_python：

Could NOT find Boost

Could not find the following Boost libraries:
        boost_python
No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT to the location of Boost.

因此，我认为缺少的是Boost-Python路径。我也尝试添加-DBOOST_LIBRARYDIR，但这似乎没有改变任何事情。

FindBoost documentation包含此关于Boost-Python的评论

请注意，Boost Python组件需要一个Python版本后缀 (Boost 1.67及更高版本)，例如适用于版本的python36或python27 分别针对Python3.6和2.7构建。这也适用于 使用Python的其他组件，包括MPI_PYTHON和NumPy。 较早的Boost版本可能使用特定于发行版的后缀，如 2、3或2.7。这些也可以用作后缀，但请注意，它们 不可移植。

我注意到Boost-python3库有后缀37(libBoost_python37.a)，所以我也尝试将蟒蛇环境与python3.7一起使用，但同样的错误仍然存在。

如何让我的cmake找到Boost-python3库？

解决方案

使用CMake3.12介绍了FindPython2和FindPython3。这重新处理了查找Python的整个过程，还改进了对Anaconda的支持。

由于您使用的是Boost 1.67，我建议您无论如何都要切换到CMake 3.12或更高版本：https://stackoverflow.com/a/42124857/2799037

如果可能，请使用您可用的最新CMake版本。
