I’m loading a not-owned-by-me library with Python’s ctypes module as ctypes.CDLL("mylib.so") which produces an error undefined symbol: g_main_context_push_thread_default because mylib.so was overlinking a lot of unneeded / unused stuff like glib.

In this particular case, I can work around this problem successfully by LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0 python ...-ing glib, but I’m curious in two generic related questions touching on how ctypes works:

1. Is it possible to ask ctypes / dlopen to ignore undefined symbols, given that I know that these undefined symbols are not used on the code path I’m interested in (or otherwise I would be okay if it crashed in a hard way)?

2. Is it possible to ask ctypes to load several libraries at once or emulate LD_PRELOAD-ing? I tried to do ctypes.CDLL("/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0") before loading ctypes.CDLL("mylib.so"), but it did not help.

Thanks!
