I just installed pgsql this morning and already encountered some difficulties. How do I compile a C/C++ client application with pgsql? Here's what I do:
gcc -c -I/usr/local/pgsql/include sample.cpp
and I get:
aggregate 'PGconn conn' has incomplete type and cannot be initialized
aggregate 'PGresult res' has incomplete type and cannot be initialized
The libpq-fe.h file *is* in /usr/local/pgsql/include
What other include files am I missing?
Also, a lot of messages seem to indicate that there is sample code under the src/ dir. Where is this? It is not under /usr/local/pgsql. Did I miss a step in the install?
thanks,
Stephen

Hi Stephan
I am using Postgresql on MacOS X with gnu 3.1
I am using this for C++ builds
g++ -I/usr/local/pgsql/include -o testlibpq0 testlibpq0.cc
-L/usr/local/pgsql/lib -lpq++
and for C build
gcc -I/usr/local/pgsql/include -o testlibpqc testlibpqc.c
-L/usr/local/pgsql/lib -lpq
You sample is C++ or C prog ?
if is C prog are you include libpq-fe.h in you source code ?
PGconn is defined in this header.

Where did you get this "sample.cpp" from? It appears to be written
incorrectly.

Look in the source-code distribution. I don't believe we install any
sample code; there's no standard place for examples in the usual system
directories.
