failing to compile #67

Closed benoitpaillard closed 9 months ago

Description

When trying to compile pyspline as described in doc, with config/defaults/config.LINUX_GFORTRAN.mk, I'm getting an error on final import test Error: /home/jony/pyspline/src/f2py/libspline.so: undefined symbol: Npy__PyLong_AsInt

Downgrading numpy from 1.24 to 1.18 solves this issue, but then breaks pandas and scipy

Steps to reproduce issue

git clone https://github.com/mdolab/pyspline.git
cd pyspline/
cp config/defaults/config.LINUX_GFORTRAN.mk config/config.mk
make
sudo pip3 install numpy==1.18
make clean
make

Current behavior

Error: /home/jony/pyspline/src/f2py/libspline.so: undefined symbol: Npy__PyLong_AsInt

Expected behavior

Testing if module libspline can be imported... Module libspline was successfully imported

Code versions

Hi, please make sure to update config.mk such that PYTHON, PYTHON-CONFIG, and F2PY are correctly configured for your python installation.

Hi, this was already adapted.

Upgrading from Ubuntu 20.04 to 22.04 solved the issue.

As a sidenote I've moved to Docker due to other issues with lib compilation https://mdolab-mach-aero.readthedocs-hosted.com/en/latest/installInstructions/dockerInstructions.html
