Graalpy not work with numpy in static-linked native-image #464
Description
Greetings!!
Graalpy is a wonderful work! You guys are brilliant!! It helped me a lot!
i've been trying to use graalpy in static-linked native-image, basic python functions are completely working perfectly.
but when it comes to numpy , it seems graalpy cannot work properly in static-linked NI.
everytime it runs into numpy code, a error occurs:
Traceback (most recent call last):

File "/graalpy_vfs/venv/lib/python3.11/site-packages/numpy/__init__.py", line 141, in <module>

from numpy.core._multiarray_umath import (
SystemError: NFIUnsatisfiedLinkError: Dynamic loading not supported
according to the stacks, i found that the _multiarray_umath is provided with a dynamic lib file.
is it possilble to run numpy code in a static NI with graalpy now?

Hi @buuuuuuug, unfortunately it's not possible. Python native extensions are compiled as dynamic modules and dynamic module loading can't work with a static libc. That's not specific to GraalPy, statically linked CPython would also not be able to load numpy installed as a module. What might work is mostly-static image with dynamically linked glibc (documentation), but then it would still load the modules and their dependencies as dynamic, which would kinda defeat the purpose of static linking.
