Thread: Using pg_config

Using pg_config

From
Peter Eisentraut
Date:
I was unable to build the libpq-based driver because it apparently makes some
hard-coded assumptions about the installation paths which did not work on my
system.  It'd be better if pg_config were used to detect the installation
paths.  I've attached a patch for that here.  I'm not sure how that works on
Windows, though.  Comments?

It's not a problem on Windows as we build using VC++ with win32.mak. We don't support Mingw builds as we don't
currentlyhave any configure code to allow the use of the Microsoft DM instead of iODBC or unixODBC. 

Can you apply the patch, or shall I?

Regards, Dave.

universal path

From

Hi Dave,

could you please change the path's in win32.mak and psqlodbc.wxs (and
other places)

from:
C:\Program Files\PostgreSQL\8.1\include

to:
%programfiles%\PostgreSQL\8.1\include

since not everybody is installing Windows on C:\ and the path \Program
Files\ is not always the same in different international installations.

regards
Johann

I think this could be made to work if there is interest.  It seems that
the current driver manager detection code might be pretty useless
anyway.  Note that we don't even link with libodbcinst.  All we need
are the header files <sql.h> etc., which are the same everywhere.

I just did.

I think it is worth doing given that we build PostgreSQL and Slony in
mingw now. As you say, it shouldn't be too difficult.

Thanks. Just in time for 08.01.0005 which was just tagged!

installer

From

Hi Dave,

Even though I don't build the installer there are still seven occurences of:

"C:\Program Files\PostgreSQL\8.1\... " />

in psqlodbcm.wxs. But I'm not sure whether a universal path will work here.

And maybe

SET VERSION="08.01.0006"

in Make.bat is too optimistic.

Johann
