I've just checked and they're const char*.

I also commented out my original EXEC SQL line and re wrote it as an
explicit connect and it compiled, so I started adding the variables back  in
and it still compiles.

I don't understand :-[ And I haven't changed the Makefile either.

Postgres4.7.2

Hello Kevin,

Are you sure that target & user are declared as string pointers (char *)?

The only way I could get similar errors to those you describe was by
declaring target & user as simple char variables in ECPG's declare
section.

I'm using gcc 3.3, Postgres 7.3.2 on SuSE 8.2.

Regards - Paul
