ImportError cannot locate symbol "PyCapsule_Type" #20

Closed defencedog closed 1 year ago

defencedog commented 1 year ago

I have successfully compiled & installed the git version; but when I import optima library in ipython this happens

In [1]: import optima
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-6df14caa3eef> in <cell line: 1>()
----> 1 import optima

----> 1 from optima.optima4py import *

ImportError: dlopen failed: cannot locate symbol "PyCapsule_Type" referenced by "/data/data/com.termux/files/usr/lib/python3.9/site-packages/optima/optima4py.cpython-39.so"...

There is no missing library as well

~ $ ldd "/data/data/com.termux/files/usr/lib/python3.9/site-packages/optima/optima4py.cpython-39.so"

Ok done, on Android this way results no symbol errors

git clone https://github.com/reaktoro/optima.git
cd optima && mkdir build_aarch64
cd build_aarch64

I have python 3.9 from TUR repo

export LDFLAGS=-lpython3.9 && MATHLIB=m cmake .. -DCMAKE_INSTALL_PREFIX=$PREFIX/local

then in build directory

cd /data/data/com.termux/files/home/optima/build_aarch64/python/package
pip install .
