libfastcgipp < error while loading shared libraries

Question

Pretty new to c++, coded a few years in other languages though. I been stuck all day with this issue that I can't seem to figure out.

When I run the code published here: http://www.nongnu.org/fastcgipp/doc/2.1/a00004.html I get the following error message:

error while loading shared libraries: libfastcgipp.so.2: cannot open shared object file: No such file or directory

Using ubuntu 13.10

I can build the code with out problem, but not run it. There is a libfastcgipp.so.2 and libfastcgipp.so in /usr/local/lib/

I tryed creating a symlink from /usr/lib/libfastcgipp.so

Answer 1

I solved the issue by creating a symlink to the file as first explained above, but added the trailing number 2, the version number, at the end.

e.g: ln -s /usr/local/lib/libfastcgipp.so.2.0.0 /usr/lib/libfastcgipp.so.2

UPDATE

Ran in to this issue again and couldn't figure out the same issue again, so I'm posting a docker file that will get your fastCGI++ script running (probably only me that will use this, but anyway ...)
