Hi Luigi,
Thanks for your response. I am attempting to build QuantLib myself to turn on higher-resolution dates for intraday analysis.
Here are the commands I am using to build QuantLib:
(base) matthew@Matthews-MacBook-Pro-5 Documents % tar xzvf QuantLib-1.36.tar.gz
(base) matthew@Matthews-MacBook-Pro-5 Documents % cd QuantLib-1.36
(base) matthew@Matthews-MacBook-Pro-5 QuantLib-1.36 % ./configure --with-boost-include=/opt/homebrew/include/ \
--prefix=${HOME}/Documents/QuantLib-1.36_build --disable-shared \
CXXFLAGS='-O2 -stdlib=libc++ -mmacosx-version-min=10.9' \
LDFLAGS='-stdlib=libc++ -mmacosx-version-min=10.9’
(base) matthew@Matthews-MacBook-Pro-5 QuantLib-1.36 % make -j8
(base) matthew@Matthews-MacBook-Pro-5 QuantLib-1.36 % make install
I can compile and run the C++ examples successfully.
I then try and build QuantLib-SWIG-1.36:
(base) matthew@Matthews-MacBook-Pro-5 Documents % tar xzf QuantLib-SWIG-1.36.tar.gz
(base) matthew@Matthews-MacBook-Pro-5 Documents % cd QuantLib-SWIG-1.36/Python
(base) matthew@Matthews-MacBook-Pro-5 QuantLib-SWIG-1.36 % export CXXFLAGS='-O2 -stdlib=libc++ -mmacosx-version-min=10.9’
(base) matthew@Matthews-MacBook-Pro-5 QuantLib-SWIG-1.36 % export LDFLAGS='-stdlib=libc++ -mmacosx-version-min=10.9’
Here I am using a conda python39 environment to build/install:
(py39) matthew@Matthews-MacBook-Pro-5 Python % /Users/matthew/opt/anaconda3/envs/py39/bin/python3 setup.py build
This generates some warnings related to compatibility between arm and x86 (I’m building on M1):

This appears to run successfully (though the package name contains x86):

Then trying to import QuantLib raises an error:

Thanks for your help!
