Brian,

Thanks for documenting this--I'm glad it worked for you. You're right, a
Fink install of Qt can make things a little hairy. My workaround for
this is to comment out the "source /sw/bin/init.sh" line that Fink uses
to get it loaded onto your PATH: if that is not commented out, then
$QTDIR will point to /sw rather than /Developer/qt. That's another
approach to try as well, for anyone who's interested.

| Thanks for the reply - so I finally got it working and all is well in

|
| My main problem was a combination of the Fink QT installation crossing
| with your binary installation. Somehow it was pulling some pieces from
| the Fink install and including them with the /Developer/qt install.
|
| Two things needed to be done for me to successfully compile the
| postgresql adaptor for Aqua. First, I removed all things Qt from the
| Fink environment (except qt3-shlibs, because kde depends on them).
| Secondly, I needed to set an environment variable called QMAKESPEC in my
| ~/.profile. I set it to QMAKESPEC=darwin-g++. I just added it to the
| other Qt environment variables that you mentioned in the instructions.
| Don't forget to add it to the export line.
|
| Then I followed the directions in the Qt Users Manual about compiling
| the SQL drivers.
|
| My postgresql installation (just configured - not installed - in order
| to supply the necessary header files) was installed in /Users/Shared/.
| My regular postgresql installation was in /usr/local/pgsql/ (I typically
| install from source). After navigating to the source files for the sql
| drivers (/Developer/qt/plugins/src/sqldrivers/psql) I was ready for the
| qmake command.
|
| qmake -o Makefile
| "INCLUDEPATH+=/Users/Shared/postgresql-7.4.6/src/include
| /Users/Shared/postgresql-7.4.6/src/interfaces/libpq"
| "LIBS+=-L/usr/local/pgsql/lib -lpq" psql.pro
|
| Then use 'make' to install it (automatically) in the plugins directory.
| Open Qt Designer > Database Connections and with any luck, you should
| see the postgresql adaptor in the drop down menu.
|
| Phew !! I am happy to say I have all the pieces to make PyQt database
| applications...finally.
|
| Thanks again for putting together all the pieces to make this happen.
