我有以下设置，可以将增强库添加到C++项目中。

/opt/boost/release

包含我的boost

include

和

lib

目录。我的boost版本为1.65.1，根据文档使用以下命令构建

$ sudo ./bootstrap.sh --prefix=release --with-python=python3 --with-icu=
$ ./b2 install -j 4

我尝试了使用和不使用

——使用python=python3

标志

工作空间增强建造 main.cpp 我得到以下错误

因为要将可执行文件链接到boostpython/Numpy，所以还需要提供Python符号

如果您不需要Python，最简单的解决方案是在glob中添加

libboost\u numpy.so

到

exclude

。如果您确实需要Python，一个快速修复方法是将

-lpython

添加到

BOOST.build

中的

linkopts

（这不是我推荐用于生产的解决方案，因为您无法控制Python版本等）

您可以使用，由Bazel组织维护

这不是答案，但你试过了吗？是的，我试过了。该版本会自动将依赖项下载到项目中。无法让它工作。我要试试这个，然后报告。感谢您的回复。注意，您的boost_构建可能依赖于其他boost_构建dep-不确定您是否可以简单地使用一个规则引用用户选项数组中的多个lib（我不是专家！）我在Mac上尝试了您的解决方案，但它不起作用Bazel通常在Ubuntu IMO上效果最好
