Hello!

I sent the email just before, but I took some mistakes in it. So, I send this again.


I would like to use FAUSTPy, but I could not pass "python3 setup.py test".
So, I am wondering if you give me some advice.

The environments I tried are below.


1..
Python 3.8.10
CFFI 1.15.0
NumPy 1.21.4
FAUST2 2.38.4 *
Linux Mint 20.2 x86_64

2...
Python 3.8.10
CFFI 0.6
NumPy 1.21.4
FAUST2 2.38.4 *
Linux Mint 20.2 x86_64

*...I built FAUST2 from the branch "faust2-debugtravis"

Also, I attached the errors as error.txt.



Thank you,


Yoshiki Sato
