# Normally on unix-like platforms, extensions are built as "MODULE" libraries
|
|
# and do not explicitly link to the python shared object. This allows for
|
|
# come greater deployment flexibility since the extension will bind to
|
|
# symbols in the python interpreter on load. However, it also keeps the
|
|
# linker from erroring on undefined symbols, leaving this to (usually obtuse)
|
|
# runtime errors. Building in "SHARED" mode with an explicit link to the
|
|
# python libraries allows us to build with the expectation of no undefined
|
|
# symbols, which is better for development.
|

# TODO(laurenzo): Windows requires linking against the PYTHON_LIBRARIES

# TODO(laurenzo): OSX requires allowing undefined (-undefined dynamic_lookup)
