Yay :-)

  Here are a few notes about Tim's wiki instructions after a

Its working for me with both 0.8.1 branch and trunk

Like this you mean?

python configure.py -n

Ok - in the instructions I suggested to build in your home dir like this:

cmake -D CMAKE_INSTALL_PREFIX=$HOME/apps/ ..

Where does ./bootstrap come from?

Right I think Magnus Homann has done similar on the CMake backport he
did to 0.8. branch. Ill take a look.

I think you can set pretty much everything in ccmake or by editing
CMakeCache.txt (==hack I think). Did you have probelsm with gdal.so
etc? Will be nice if we can get the mac version to use .dylib rather.
In openModeller I edited cmake/FindGDAL etc scripts to achieve this
but I dont know if thats the best way...

Hmm Im not sure how it can tell either. Martin? I guess we could scan
for /Applications/QGIS* and then do a little scripting to get the
highest version no....(in cmake/FindGRASS )

specify CMAKE_OSX_ARCHITECTURES as i386;ppc

I havent been able to successfully make a universal binary yet - I
guess some of my deps need to be compiled as unoversal too. Did you
see in my wiki notes where I should have done this for gsl etc? Or
does it happen automagically?

Ok this is fixed in SVN. By default the pedantic flag is on and all
warnings are treated as errors. You can turn the pedantic flag off in
ccmake (though I recommend you keep it on and let us know if you get a
similar warning).

Great thanks!


Many thanks for your fantastic work once again getting those
frameworks done! They really do make getting up & running on the mac a
doddle....
