Question

我刚刚使用

编译并安装了来自源代码的boost

$pwd

/Downloads/boost_1_58_0

./b2 threading=multi link=static runtime-link=static cxxflags="-stdlib=libstdc++" linkflags="-stdlib=libstdc++"

并在构建完成后收到消息，

Boost C ++库已成功构建！

应将以下目录添加到编译器包含路径：

/Downloads/boost_1_58_0

应将以下目录添加到链接库库路径：

/Downloads/boost_1_58_0/stage/lib

现在我正试图使用sudo pip install .

安装lib torrent的python挂起

我收到错误消息b2: command not found，因为我知道b2命令在我的位置从哪里构建boost，我将setup.py更新到特定路径，

但是当我尝试sudo pip install . lib torrent的python绑定时，我得到以下消息。

Complete output from command python setup.py egg_info:
    Unable to load Boost.Build: could not find "boost-build.jam"

    BOOST_ROOT must be set, either in the environment, or
    on the command-line with -sBOOST_ROOT=..., to the root

    and in these directories from BOOST_BUILD_PATH and BOOST_ROOT: /usr/share/boost-build.
    Please consult the documentation at 'http://www.boost.org'.

按照第一个回答中提到的步骤操作后，我尝试运行make但是它出现了以下错误：

由于您似乎不介意使用boost-build进行构建，因此最简单的方法是：

export BOOST_ROOT=/Downloads/boost_1_58_0
export BOOST_BUILD_PATH=$BOOST_ROOT/tools/build
export PATH=$PATH:$BOOST_BUILD_PATH/src/engine/bin.macosxx86_64
echo "using darwin ;" >~/user-config.jam

cd libtorrent/bindings/python
b2 boost=source

前4行基本上是安装boost-build（b2）。在构建b2时假设输出目录是bin.macosxx86_64。

这将构建libtorrent python模块，但它不会安装它。
