The exec sql should be there after running ecpg. ecpg is a preprocessor. You
have to feed you're source (should be named file.pgc BTW) through ecpg
before running cc. That is:
ecpg tryecpg.pgc
cc -o tryecpg tryecpg.c -lecpg -lpq

If this was not the problem we need more details.

The reference is pretty outdated but the source comes with three examples.
Oracle's Pro*C manual however is a good reference for the syntac of embedded
SQL, although it does not comply with the standard on some parts.
