[pkg] Make sure the gecode extension build never ever fails (closes #158948)
In some cases (eg, windows without Visual Studio installed),
distutils/setuptools build_ext.run() may raise exceptions other than
CompileError. By catching all exceptions, we can make sure rql's
setup.py never fails, which should help dumb package managers such as
pip.
This package provides base library for the Relationship Query Language
INSTALL
-------
the standard way:
python setup.py install
building rql binary extension in place:
python setup.py build_ext --inplace
