Обсуждение: compilig libpq with borland 5.5

Uh, what version of Postgres are you testing?  Would you email the
output of the compile so we can see why it isn't find it?  My guess is
that borland CC isn't configured to find the Windows include directory.

Just in case you can't get it working, you can always take a msvc
compiled libpq.dll and create a static library out of it with the
'implib' utility using the underscore option.

You are correct about static libraries.  If you have a 'COFF' (usually
microsoft in this context) static library, the only tool I know of to
get it working with the Borland stack is the Digital Mars COFF->OMF
converter, which works, and is the only way to go if you have a static
library which is not a stub for a dll (fully static) and don't
have/can't compile the source.

Dynamic libraries, however, can be shared between the compilers.  You
can either load all the symbols with LoadLibrary, etc, or generate a
static library.   Borland's implib.exe utility generates a static
library from any dll so you don't have to use LoadLibary, .etc, just
the header for the symbols from the library which you want to use.

Format problems between the compilers are one of the many reasons why
static libraries (except for statically loaded .dll) have fallen out
of favor...you hardly ever see them anymore.

I have applied the attached patch to CVS HEAD and 8.3.X to sychronize
bcc with msvc makefiles.  Please let me know if you have further
problems.  Thanks for the report.

It can be made from 'make distprep'. and def file is also made.
However, I make it except windows environment.
