如何让 python 在 osx 上加载 dylib

发布于 2024-08-26 00:18:26 字数 655 浏览 3 评论 0原文

尝试从当前的“.”中加载共享库osx 上单元测试中的 dir。

在 Linux 和 Netbsd 上有效的是一个符号链接 _mymodule.so --> ../.libs/libmymodule.so

但在 osx 上，python 的 import mymodule 找不到

_mymodule.dylib --> ../.libs/libmymodule.dylib

我尝试添加

export DYLD_LIBRARY_PATH=.:$DYLD_LIBRARY_PATH

到脚本 env 中，nogo。任何帮助表示赞赏。

更新 4/6/10：

用下面 krunk 的信息解决了。但仅仅将 dylib 复制或 ln -s 为 .so 名称并不能完全解决问题。还是无法加载。但是告诉 libtool 将 lib 与 -module 标志链接起来会创建一个可以加载的 .so lib。该库的 Python 版本现在可以使用。

现在如果我能让 perl lib 工作就好了。我正在构建 swig perl、python、ruby 和 lua 库，这个修复只让 python 和 lua 工作。

Trying to load a shared lib out of the current '.' dir in a unit test on osx.

What works on Linux and Netbsd there is a symlink _mymodule.so --> ../.libs/libmymodule.so

but on osx, python's import mymodule won't find

_mymodule.dylib --> ../.libs/libmymodule.dylib

I've tried adding

export DYLD_LIBRARY_PATH=.:$DYLD_LIBRARY_PATH

to the script env, nogo. Any help appreciated.

update 4/6/10:

Solved with the info from krunk below. But just copying or ln -s'ing the dylib to a .so name didn't solve it completely. Still wouldn't load. But telling libtool to link the lib with the -module flag created a .so lib that would load. Python version of the lib works now.

Now if I could just get the perl lib working. I'm building swig perl, python, ruby, and lua libs and this fix only got python and lua working.

在 OS X 中也只需使用 *.so 作为模块扩展即可。我模糊地记得无法加载 .dylib，结果发现这是 python 本身的问题。。。但我现在找不到邮件列表帖子。

不过，请放心，即使在 OS X 上，您也遵循使用 *.so 的标准做法。整个框架中唯一的 *.dylib 是 libsvn_swig 的。

Just use *.so as your module extensions in OS X too. I have a vague memory of not being able to load .dylib's and it turning out to be an issue with python itself. . . but I can't find the mailing list post now.

However, rest assured you're following standard practice by using *.so's even on OS X. The only *.dylib's in the entire framework are the libsvn_swig ones.
