Linking statically to libpq

I have built libpqxx-2.6.9 on windows (including implementing the 2 workarounds noted on the main page for Win32). All went well but I have a question.

 

I created libpqxx_static.lib but it seems to work against the libpq.dll by default and is even nice enough to copy it into the <src>/lib directory for me. I’d like it to link statically to libpq.lib and not require the DLL. Is it set up so that if I link my apps against the static versions of both libpq and libpqxx I won’t need the DLL, or is that just a hard requirement of using libpqxx—i.e., must include the libpq.dll?

 

What defines do I need to make that happen?

 

Thanks in advance!

Hello Bob,

My apologies for the late reply; I was unusually busy and hoped a Windows

In the latest versions, PQXX_PQ_STATIC should do it.  Look for that macro
in include/pqxx/compiler-public.hxx.  It's pretty new so you don't see it
there, then your version doesn't support it yet.  Try the latest
development snapshot here:

    http://pqxx.org/~jtv/tmp/pqxx/

Note that that version does have some problems with cursors and
robusttransactions at the moment.
