[英]In BAZEL, Is there a way to prevent dependency C/C++ headers from being propagated to dependent library?
[英]Add boost library as Bazel dependency c++
我有以下设置将 boost 库添加到我的 C++ 项目中。 /opt/boost/release
包含我的 boost include
和lib
目录。我的 boost 版本是 1.65.1 并按照文档使用以下命令构建。
$ sudo ./bootstrap.sh --prefix=release --with-python=python3 --with-icu=
$ ./b2 install -j 4
我试过有和没有--with-python=python3
标志。
new_local_repository(
name = "boost",
build_file = "boost.BUILD",
path = "/opt/boost/release",
)
cc_library(
name = "boost",
srcs = glob(["lib/*.so*"]),
hdrs = glob(["include/**/*.hpp", "include/**/*.h"]),
includes = ["include"],
visibility = ["//visibility:public"],
linkstatic = 1,
)
cc_binary(
name = "experiments",
srcs = ["main.cpp"],
deps = [
"@boost//:boost",
],
)
#include <boost/progress.hpp>
int main()
{
return 0;
}
当我使用 bazel build 命令构建它时
bazel build //experiments:experiments
我收到以下错误。

由于您将可执行文件链接到 Boost Python/Numpy,因此您还需要提供 Python 符号。
如果您不需要 Python,最简单的解决方案是添加libboost_numpy.so
以exclude
在您的 glob 中。 如果你确实需要的Python,速战速决是添加-lpython
到linkopts
在BOOST.build
(这不是一个解决方案,我会建议进行生产,因为你有过Python版本没有控制,等等。)
您可以使用由 Bazel 组织维护的rules_foreign_cc 。
