[pgrouting-dev] Building TRSP branch

[Steve Horn]

Was not able to find these libraries via package manager, but I did get
pgRouting and dependencies installed manually.

The "cannot find -lgmp" referred to a dependency of CGAL that needed to be
installed ( http://gmplib.org/manual/Installing-GMP.html#Installing-GMP )

Also of note is that CGAL needs a specific version of the Boost libraries
to work (1.41).
After successful pgRouting make/make install then I ran the
driving_distance function to test and got this:

“Error while loading shared libraries: libboost_thread.so.1.41.0: cannot
open shared object file: No such file or directory"

Used the information in this blog to correct that error:
http://somethingididnotknow.wordpress.com/2012/02/17/fix-the-error-while-loading-shared-libraries-libboost_thread-so-1-48-0-cannot-open-shared-object-file-no-such-file-or-directory-error/


Hope this helps someone in the future.

Steve: Haven't done a deep dive into the TRSP functionality -but I am
impressed at the surface. Does it use an A Star algorithm at the core?

Thanks for your efforts on this!
