I'm sure that it doesn't.

The above sounds reasonable, but I have never tried it.

No, as the announcement and README clearly stated, I configured as
follows:
$ configure --with-CXX --prefix=/usr --sysconfdir=/etc --docdir=/usr/doc/postgresql-7.1rc4

I *knew* that I was going to get myself into trouble by responding with
more than "I dunno"...
I hope that you don't mind but I'm CC-ing pgsql-ports so others can
benefit from this too.

I just did the following (with 7.1rc4):
$ cd src/interfaces/odbc
$ make
The above produced psqlodbc.dll which seems to be exporting the "right
stuff." How do I test this -- I have never used ODBC before.

I'm quite willing to include ODBC support in my distribution. However I
will only include a Cygwin psqlodbc.dll -- including a straight Win32 one
is confusing and could cause some problems. There are too many Cygwin
to non-Cygwin interaction problems on the Cygwin mailing list already...

I just did the following (with 7.1rc4):
$ cd src/interfaces/odbc
$ nmake -f win32.mak
The above produced Win32 psqlodbc.dll and seems to be much easier than
trying to follow the steps in src/interfaces/odbc/readme.txt.
Anyway, if we can verify that Cygwin psqlodbc.dll works correctly, then
I will add the --with-odbc option when I configure from now on.

How do I test this -- I have never used ODBC before. Here are some messages I sent about my experience with this a few months back. <http://www.postgresql.org/mhonarc/pgsql-odbc/2001-02/msg00010.html> <http://www.postgresql.org/mhonarc/pgsql-odbc/2001-02/msg00011.html> > I'm quite willing to include ODBC support in my distribution.

There are too many Cygwin > to non-Cygwin interaction problems on the Cygwin mailing list already... A pure Cygwin version is fine by me, if one is available. When I asked for information about how to build an ODBC DLL that works, Hiroshi Inoue was the only person to respond with any help, and he steered me to the VC++ method given by the readme.txt. That worked and I left it at that. The messages behind the above URLs recount my problems trying to use the DLL built in response to configuring with '--with-ODBC'. OTOH, wouldn't a non-Cygwin DLL be useful for those cases where the client machine isn't running the postgres/postmaster service, but wants to access such a service on a remote machine? It would be a shame to have to install Cygwin just to allow that ODBC DLL to run. > I just did the following (with 7.1rc4): > > $ cd src/interfaces/odbc > $ nmake -f win32.mak > > The above produced Win32 psqlodbc.dll and seems to be much easier than > trying to follow the steps in src/interfaces/odbc/readme.txt. When I get some time I'll try that and see if the resulting DLL works for me now. -- Fred Yankowski fred@OntoSys.com tel: +1.630.879.1312 Principal Consultant www.OntoSys.com fax: +1.630.879.1370 OntoSys, Inc 38W242 Deerpath Rd, Batavia, IL 60510, USA

Good point, but... > It would be a > shame to have to install Cygwin just to allow that ODBC DLL to run. ..one would only have to install cygwin1.dll -- not all of Cygwin.
