cannot generate libnfs_wrap.c

[sanjosh]

Sorry to bother you but I am a newbie in swig and can't figure this out.

I am running ubuntu 14.04. I already installed libnfs, swig and pcre (apt-get install pcregrep libnfs-dev swig) but it seems the libnfs_wrap.c is not getting generated

Running setup.py does not seem to generate the same output as seen here
http://rickhau.github.io/blog/2015/05/08/install-libnfs-python-library/

swig is installed in /usr/local/bin, so is pcre-config

Is something missing in my setup ?

$ sudo python setup.py install

Hi, Ubuntu ships really old versions of libnfs which lacks some symbols that the python bindings need. Please try to remove libnfs and the devel package using apt-get and instead build and install libnfs from sources.

I did build libnfs, swig and pcre from source but that didn't solve the problem.

Is there some debug or verbose flag I can enable to find out why swig isn't generating the libnfs_wrap.c ?

I don't know much about swig or python building modules. :-( Building the module on newer versions of ubuntu works though. I can try setting up a 14.04 VM and see if I can get it to build.

Solved! Before running setup.py, make must be run inside the libnfs folder:

cd libnfs-python/libnfs
make

Cheers!

Thanks. INSTALL has been updated.
