hi i'm tring to have gdal-grass installed on osx using grass7+gdal svn,
i compiled gdal, then grass,
then cd in the gdal source/frmts/grass
run make dist to create the tar.gz package.
i configured it using : ./configure --with-gdal=/usr/local/gdal/bin/
gdal-config --with-grass=/usr/local
You should be able to build the GRASS plugin off my GDAL framework, to
avoid unnecessary duplication, and retain all the other formats built
into my framework. Though there might be a version issue between GDAL
1.7/GRASS plugin and my GDAL 1.6 framework.
I'll look into and get back to you.
