Re: Compiling pgsql C/C++ interfaces on Win not using Cygwin

Hi Tomás,

Include the lib in your project (Project => Settings =>Link Tab => Object
Library Modules). You have two options (for debug and release modes):

1) libpq.lib (static version, you don't need to distribute libpq.dll)
2) libpqdll.lib (dinamic link library, you need to distribute libpq.dll)

Also don't forget to set the directories under Tools => Options =>
Directories (Include Files and Library Files).
In the manual there are some info about compiling the libpq libraries in
Win32. I just don't remember where exactly.

PS: I'm assuming you are creating an application with VS6, since you
mentioned that.
