When I try to build the libpq files this is what happens:

So I am still missing something.

Hi,
Unfortunately the regular PostgreSQL distribution does not come with a
debug version of the libPQ library, but libpqxx links to this version of
the libPQ library for the debug build. The solution: download the
PostgreSQL source, go to the same directory as in the normal
distribution(src\interfaces\libpq, that should work AFAIK) and build the
debug version of libpq. The precise way to do this should be in a README
in there somewhere, I can't really elaborate right now because I'm in a
shabby internet cafe in Kanchanaburi, Thailand, instead of at home. :-/
Anyway, after building the debug version (and the release version as well,
while you're at it), you should then point the path in your COMMON file to
your postgreSQL source directory. Then libpqxx should build just fine.
Side note to Jeroen: I'll update the README to cover this stuff when I get
back. Apparently there is still some source for confusion! :-)
Cheers,
Bart
