I've just modified the extension with .c instead of .cpp and run:
vicbsd# gcc -I /usr/local/include/ prova.c -o prova -Lpq
/var/tmp//cc86RZZl.o(.text+0x25): In function `main':
: undefined
reference to `PQconnectdb'
Nothing seems to be changed!
Thanks
anyway.

If it's a C program, you should name the file .c otherwise gcc is
likely to consider it a c++ program.
2. If it's a c++ program, use g++
to compile and link to make sure you
get all the right libraries and
paths.
3. Use -lpq to link to the postgresql client library. You may
need a -L
so it looks in the right place.
Hope this helps,
