hello

i've tried to write a stored function in C++, using the libpq library, but
the g++(3.3.1) was unable to pass through the headers. there are a lot's
of reserved words used in structs as member names, such as delete,using,
namespace, and so on.

i'm using pgsql 7.3.4.
how can I fix it? i think so, i should modify the header files, i've tried
to put it into an ``extern "C" {...}'' block, but i didn't solve anything.

any ideas?

Bye,

Try putting extern C, around include statements for libpq headers.

You need to redefine several reserved names before may include 
postgresql headers. This is an extract what I needed:

#define using __using
#define typeid __typeid
#define typename __typename
#define namespace __namespace
#define delete __delete
extern "C"
{
#include "postgres.h"
#include "executor/spi.h"
#include "funcapi.h"
}
#undef using
#undef typeid
#undef typename
#undef namespace
#undef delete

Regards,
Andreas

Is libpq++ gone?

No is still there and is working great but the OP need to write a
SP in C++.
