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!

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, -- Martijn van Oosterhout <kleptog@svana.org> http://svana.org/kleptog/ > Patent. n. Genius is 5% inspiration and 95% perspiration.
