    Building GDAL 1.9.x with ESRI FileGDB support on OS X Lion


Download the SDK from ESRI's website http://resources.arcgis.com/content/geodatabases/10.0/file-gdb-api
Extract the SDK, and put the contents of the directory in a known location, I used ~/local/filegdb. Here's an example path to one of the files: ~/local/filegdb/lib/libFileGDBAPI.dylib
I use ~/local/filegdb so it can stay isolated in it's own place. You can put it anywhere, but the next few steps might be different.
Go into the directory containing the FileGDB SDK, e.g. ~/local/filegdb
ESRI built these dylib's using @rpath's, so to avoid needing to mess with DYLD_LIBRARY_PATH, I updated the @rpath's using install_name_tool. There might be a more elegant way to handle this. If so, comments are welcome!
Here are the commands I used to patch the dylibs, this is not required if you want to use DYLD_LIBRARY_PATH yourself:

    install_name_tool -id "$(pwd)/lib/libFileGDBAPI.dylib" ./lib/libFileGDBAPI.dylib
    install_name_tool -change "@rpath/libfgdbunixrtl.dylib" "$(pwd)/lib/libfgdbunixrtl.dylib" ./lib/libFileGDBAPI.dylib
    install_name_tool -id "$(pwd)/lib/libfgdbunixrtl.dylib" ./lib/libfgdbunixrtl.dylib


To verify the paths, use otool -L lib/libFileGDBAPI.dylib and otool -L lib/libfgdbunixrtl.dylib and make sure the paths are correct
We need to make some changes to the configure.in script for GDAL now, since the FileGDB config script hasn't yet been updated for the OSX FileGDB SDK
In the GDAL source root, edit the configure.in and replace it with:

1.9.0 https://gist.github.com/2005082
1.9.1 https://gist.github.com/2784084
1.9.2 https://gist.github.com/5051253


In the GDAL source root, run ./autogen.sh to re-create the configure script
Now run the configure script:

    ./configure --with-fgdb="$HOME/local/filegdb"


The configure script has many options, here is the configure line I use for my custom build: https://gist.github.com/2005091, if you have other GDAL builds on your machine (e.g. homebrew) that you don't want to interfere with, I recommend at least using --prefix="$HOME/local" or some other place on your machine besides /usr/local (default for homebrew) or /opt/local (default for MacPorts).
If it worked properly, you should see in the output of configure indicating yes for FileGDB support
Build it:

    `make && make install`


If everything worked, it's time to test it out! Here's a test file: http://trac.osgeo.org/gdal/raw-attachment/wiki/FileGDB/test_fgdb.gdb.zip

    which ogr2ogr        # make sure it's the correct ogr2ogr first
    ogrinfo --formats    # list out the formats
    ogrinfo ~/Downloads/test_fgdb.gdb
    
    #convert FileGDB directly to PostGIS
    ogr2ogr -f "PostgreSQL" PG:"dbname='somedatabase' host='localhost' port='5432'" ~/Downloads/test_fgdb.gdb

Using this build of GDAL in a KyngChaos build of QGIS

# save your current GDAL so you can put it back if you want
cp /Library/Frameworks/GDAL.framework/Versions/1.8/GDAL /Library/Frameworks/GDAL.framework/Versions/1.8/GDAL_orig

# symlink the custom GDAL build to the place QGIS looks
rm /Library/Frameworks/GDAL.framework/Versions/1.8/GDAL
ln -s ~/local/lib/libgdal.dylib /Library/Frameworks/GDAL.framework/Versions/1.8/GDAL

Note: to select one in QGIS, go to Add Vector Layer -> select the Directory radio button -> Select your .gdb directory
I had some problems opening certain FileGDB's. I believe the API only supports FileGDB's created with ArcGIS 10.0+.
