You need to link against postgres.exe to get access to these symbols. I don't recall if the mingw linker allows you to just specify the EXE file these days, but I think it does. If not, you'll need to create an import library from the EXE and link to that (the binary distribution only ships with import libraries for MSVC, but mingw can't use standard windows import libraries, so you need to create your own there) -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
