Hi,

I'm a core-developer for PyInstaller. We would like to enhance cython support in PyInstaller and resolve dependencies of cython-compiled modules automatically. This would ease freezing cython modules with PyInstaller a lot and thus help users including cythonized-modules into their shipped application.

For us, the most elegant way to get the dependencies would be to have the list of imported modules in the .so-file. E.g. some simple string marked by some cookie which is easily grepped out of the binary.

Is there any chance to get suche a list into the .so/.dll-file?

It's not clear how to embed such information deterministically into the so/dll file (which are produced by the C compilers), but if you had/could create the generated C files we do put some metadata at the top of those when compiled with cythonize, e.g. /* BEGIN: Cython Metadata { [JSON data about cimports, distutils options, etc] } END: Cython Metadata */ We could consider putting imports there as well.

If you like, you can comment directly on our related ticket: https://github.com/pyinstaller/pyinstaller/issues/1674
