I would also suggest to have a look at examples/minigp.c: it should be
simpler to simply evaluate strings on your side (and do something with
the GEN result, e.g. convert them to characters strings ready for output)
than to set up and communicate with a separate gp process.

N.B. Have a look in git's 'master' branch, which implements a (nearly)
full-fledged gp in 30 lines [ the one from 2.7.* lacks a lot of features
because the necessary modules had not yet been moved to libpari ].
