Cygwin install scipy error on compilation

I am trying to install scipy under cygwin with pip, unfortunately I have some compilation errors! I attach log files. I have searched on web but have found nothing.

thanks

I expect to find a solution to this compilation problem! Since I cannot intervene in the code, I don't have much room for action.

I spent a lot of time on install scipy but now I managed!

My configuration on Cygwin : python 3.9.16 python3-devel 3.9.10.1

from github install OpenBLAS git clone https://github.com/xianyi/OpenBLAS.git make; make install

then pip install scipy==1.9.3 (the last version 1.10.1 doesn't work! strange error: M_PI not definded in some step of cc compilation!?!?!)

and finally I installed Scipy!!!!

Another way (more clean): install python for windows, change PATH in .bashrc, put first the path /cygdrive/c/Users/myusername/AppData/Local/Programs/Python/Python311 in PATH variable)
