But the actual errors you run into happen while compiling postgres itself,
right?  You may want to come over the the libpqxx-general mailing list
(see http://pqxx.org/ ) for help with libpqxx-specific problems.

From what I've heard, the Windows installer doesn't install the header
files for libpq, and those are needed for compiling libpqxx (or any other
program that uses libpq).  That's why you need the postgres source
archive.  The paths are a painful obstacle; there just don't seem to be
any real standards for these things on Windows.

I guess there really ought to be a separate "development package" of
postgres for Windows like there is for other systems.  The problem seems
to be that Windows lacks the necessary compiler standards--a development
package would have to be compiler-specific.  :-(

You should be able to get away with compiling just the Release version of
libpqxx if that's what you want, using the Release version of libpq, and
just "stealing" the libpq headers from the postgres source tree.  But
chances are that you'll want to debug your software sometimes, if only
during development, so it's better to have both Debug and Release versions
of everything available.
