I'm going to hold off merging this until speaking with @orangejulius

It might be that the original intent of fb62faa was to avoid placing the lib files in /libpostal/lib and therefore not being on LD_LIBRARY_PATH. [edit] Also the libpostal.h header file.

If that's the case then we might need to adjust this slightly so that the libs end up in the standard location but the executables end up in /libpostal, which is probably easiest done by just copying them

OK I added a second commit which should be ideal since it:

• installs to the default OS location
• copies all the libs, headers and executables across
• tests itself

I've updated this to simplify it a lot. Seems I was mistaken about $DESTDIR, which is working correctly. The address_parser binary is located in the src directory rather than the build output.

with this change it's now possible to execute the address parser directly from inside the image:

docker run --rm -i pelias/libpostal_baseimage address_parser <<< '12 foo street'
