C functions under windows

Are you building with the same compiler as the backend was built with? If you're using the binary distribution that means mingw unless you're testing the
pre-beta snapshot Dave uploaded a few days ago.

Hi all

I have postgresql server installed on a windows machine and I want to retrieve data using C functions. I followed the steps in the documentation but it

didn't work for windows. I created a .dll projects for my functions but postgres.h calls .h files that I can't find on the windows machine like <strings.h>. I
tested my functions on another server installed on a linix machine and it worked correctly. So the problem appears to be in the include files under windows.

Any idea how to solve this problem...

If you use MSVC - try to setup 'Additional include directories' for your
project. It should point to the PostgreSQL 'include' folder.

*If you're developing under nix* then I would use windows cygwin (bash
shell) e.g.
\cygwin\cygwin.bat
cd /
find . -name strings.h
you will see /usr/include
but this version of strings.h only includes string.h
to bring into environment make sure you include the /usr/include in .profile
or .bashrc e.g.
export INCLUDE=/usr/include:$INCLUDE
(then run your compile/link/make utilties)

I have added the path to the include directory of postgresql but it hasn't
already some of the files that are in linux include path like <strings.h>.
It doesn't object about postgres.h which it can find now but it objects
about strings.h

I use MSVC6 to make my dll file.

The include files that ship with your version are made for MingW, not MSVC.

You could try grabbing pg_config.h.win32 from src/include (I think it's
available in the source distribution of 8.2, if not, just get one from a
snapshot version). Then take that file and overwrite your copy of
pg_config.h with it.

strings.h is one of the differences between msvc and mingw.
