Generating pypff.dll Python module on Cygwin #19

Closed deisner closed 8 years ago

deisner commented 8 years ago

I know the Python bindings are a work in progress. On Cygwin, after following the build instructions, only the static pypff.a module was installed. I was able to get what I needed using setup.py. I mention it here to help others who run into the same problem. It might be worth including something in the Building instructions.

$ python setup.py install
$ ...
build/temp.cygwin-2.4.1-i686-2.7/libpff/libpff_compression.o: In function `libpff_decompress_data':
/home/XXXX/libpff/libpff/libpff/libpff_compression.c:127: undefined reference to `uncompress'
collect2: error: ld returned 1 exit status
error: command 'gcc' failed with exit status 1

To get past this link error, I edited setup.py and added libz to the libraries argument for setup():

setup(
    name=project_information.package_name,
    # ...
    ext_modules=[
        Extension(
            project_information.module_name,
            # ...
            libraries=['z'],
            # ...
)

Now I get /usr/lib/python2.7/site-packages/pypff.dll installed, and I can import the module in python. I realize this is probably not the right way to fix it in general; I just needed something to get it working for me.

Thanks for making this library available, by the way.

So a deflate (inflate) fallback implementation is work in progress. That should solve deployment issues around missing zlib or equivalents.
