You will have to build the libecpg lib from source first and then you can build your C source (got from .pgc file using ecpg) using something like this:
cc -I <postgres include folder> -c sample.c
cc -o sample sample.o -L <folder where libecpg is located> -lecpg

It has been my impression that PosgreSQL REALLY likes to know who it's
talking to. I'd include a user name with my connection string at the
least.
