Thanks Simon!
The build system here is the standard Python setup.py, except for this
library. That is built by the following script:
---
g++ -m64 -shared -o attach_linux_amd64.so -fPIC -nostartfiles attach.cpp
mv attach_linux_amd64.so ../attach_linux_amd64.so
echo Compiled amd64
---
There's not even an attempt at working out ${libdir} or so on. It
seems like overkill to set up a whole Autotools environment for this
one file :-(
I'm still unsure why I shouldn't just put it in the Python package
area near the cython files such as
/usr/lib/python3/dist-packages/_pydevd_bundle/pydevd_cython.cpython-310-x86_64-linux-gnu.so
Best wishes,
