Re: [Quantlib-users] Release candidates for version 1.22

[Luigi B. <lui...@gm...>]

Thanks, Marcin.  On OS X 10.14 the existing instructions worked (after
adding -std=c+11, because clang still defaults to C++03) for Python >= 3.7,
while 3.6 failed.  Instead, the following seems to work with all versions
still supported, that is, 3.6 and above:

For QuantLib, same as written in the instructions on the site:
    ./configure --disable-shared CXXFLAGS='-O2 -g0 -std=c++11
-stdlib=libc++ -mmacosx-version-min=10.9' LDFLAGS='-stdlib=libc++
-mmacosx-version-min=10.9'
    make
    make install

(The --disable-shared flag is suggested on the site and results in a
self-contained Python module instead of one that requires a dynamic library
for QuantLib installed.)

For QuantLib-Python, forget about configure and run:

    cd Python
    CXXFLAGS='-O2 -g0 -std=c++11 -stdlib=libc++ -mmacosx-version-min=10.9'
LDFLAGS='-stdlib=libc++ -mmacosx-version-min=10.9' python3 setup.py build
    python3 setup.py test
    python3 setup.py install

(you can replace python3 with whatever Python you want to use: for instance
/Library/Frameworks/Python.framework/Versions/3.9/bin/python3)

Please let me know if this works for you too.  If so, I'll update the
instructions.

Luigi
