python - ubuntu 16.04 中缺少 boost_python3

Question

我正在尝试在 Ubuntu 16.04 中安装 boost.numpy。我尝试了这些命令来安装 boost.numpy

**git clone https://github.com/ndarray/Boost.NumPy.git
 cd Boost.NumPy && mkdir build && cd build
 cmake -DPYTHON_LIBRARY=$HOME/anaconda3/lib/libpython3.5m.so ../**

在执行 cmake 后我遇到了这个错误:

检测到架构“x86_64”

-- Using Python3

    CMake Error at /usr/share/cmake-3.5/Modules/FindBoost.cmake:1677 (message):
      Unable to find the requested Boost libraries.

  Boost version: 1.59.0
  Boost include path: /home/sumit/Documents/Software/boost_1_59_0
  Could not find the following static Boost libraries:

          boost_python3

  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.
Call Stack (most recent call first):

 Boost Paths:
Include  : /home/sumit/Documents/Software/boost_1_59_0
 **Libraries**: /home/sumit/Documents/Software/boost_1_59_0/libs
Configuring incomplete, errors occurred!

另请参阅“/home/sumit/Documents/Software/Boost.NumPy/build/CMakeFiles/CMakeOutput.log”。

以前无法找到 boost 库 sp 我手动将 CmakeList.txt 库路径更改为 boost_1_59_0 库路径。当我执行 cmake 时，此路径出现在库选项中。但是仍然缺少 boost_python3。我是新手，我尝试的只是谷歌的结果。 请帮忙。

在 Ubuntu 上，boost 的库名称是: libboost_python、libboost_python-py35 或 libboost_python-py27

这意味着在 cmake 中，您需要将它们称为 python-py35 而不是 python3。或者，如果您不控制 CMakeLists.txt，您可以创建一个符号链接(symbolic link): /usr/lib/x86_64-linux-gnu/libboost_python-py35.so -> /usr/lib/x86_64-linux-gnu/libboost_python3.so

在我的 CMakeLists.txt 文件中，我有以下内容:

if(UNIX)
    set( BOOST_PYTHONLIB python-py35)
else()
    set( BOOST_PYTHONLIB python3)
endif()

find_package (Boost 1.58 REQUIRED COMPONENTS
    coroutine
    context
    filesystem
    program_options
    system
    thread
    ${BOOST_PYTHONLIB}
    chrono
    )
