编译python模块扩展时如何静态链接库 [英] How to statically link a library when compiling a python module extension

问题描述

我想修改setup.py文件，以便命令 python setup.py build编译基于C的扩展模块，该模块静态（而非动态）链接到库。

I would like to modify a setup.py file such that the command "python setup.py build" compiles a C-based extension module that is statically (rather than dynamically) linked to a library.

该扩展名当前动态链接到许多库。除了静态链接到一个库外，我想保留所有内容。我成功地通过手动修改了distutils运行的对gcc的调用来成功完成了此操作，尽管它要求我明确列出相关库。

The extension is currently dynamically linked to a number of libraries. I would like to leave everything unchanged except for statically linking to just one library. I have successfully done this by manually modifying the call to gcc that distutils runs, although it required that I explicitly listed the dependent libraries.

也许这是太多信息，但是为了清楚起见，这是在 python setup.py build脚本期间执行的最终链接命令：

Perhaps this is too much information, but for clarity this is the final linking command that was executed during the "python setup.py build" script:

gcc -pthread -shared -L/system/lib64 -L/system/lib/ -I/system/include build/temp.linux-x86_64-2.7/src/*.o -L/system/lib -L/usr/local/lib -L/usr/lib -ligraph -o build/lib.linux-x86_64-2.7/igraph/core.so

这是我的手动修改：

gcc -pthread -shared -L/system/lib64 -L/system/lib/ -I/system/include build/temp.linux-x86_64-2.7/src/*.o -L/system/lib -L/usr/local/lib -L/usr/lib /system/lib/libigraph.a -lxml2 -lz -lgmp -lstdc++ -lm -ldl -o build/lib.linux-x86_64-2.7/igraph/core.so

分发Python模块讨论了库的规范，但是只有 library_dirs是合适的，并且这些库是动态链接的。

Section 2.3.4 of Distributing Python Modules discusses the specification of libraries, but only "library_dirs" is appropriate and those libraries are dynamically linked.

我正在使用Linux环境进行开发，但是该软件包也将在Windows上编译和安装，因此我需要一种可移植的解决方案。

I'm using a Linux environment for development but the package will also be compiled and installed on Windows, so a portable solution is what I'm after.

可以有人告诉我在哪里寻找说明，或如何修改setup.py脚本？ （提前感谢！）

Can someone tell me where to look for instructions, or how to modify the setup.py script? (Thanks in advance!)

我是StackOverflow的新手，所以我很抱歉，如果我没有正确标记这个问题，或者如果我在其中犯了一些其他错误，

I'm new to StackOverflow, so my apologies if I haven't correctly tagged this question, or if I have made some other error in this posting.

推荐答案

如果其他所有方法均失败，那么总会有文献记载很少的 extra_compile_args 和 extra_link_args 扩展选项$ c> 构建器。 （另请参见此处。）

If all else fails, there's always the little-documented extra_compile_args and extra_link_args options to the Extension builder. (See also here.)

您可能需要破解一些与操作系统相关的代码，以获取特定平台的正确参数格式。

You might need to hack in some OS-dependent code to get the right argument format for a particular platform though.
