Hi, Currently the default mode of linking GDAL with proj.4 is to use dynamic loading mechanism (dlopen on Unix, LoadLibary on Windows). I believe the reason for that was that it could have make it easier to use an alternate projection engine, but apparently nobody cared enough to plug a new one, and it could be done with standard linking. One downside of the current mechanism (besides code complication) is that it requires to list the exact library name of proj4 in GDAL source code, which can change depending on the soname of proj4. And this can cause subtle issues like https://trac.osgeo.org/gdal/ticket/6881
So I'd suggest just keeping standard linking mechanism, and renaming the current --with- static-proj4 configure flag as --with-proj4, as the current name is confusing, and making it the default behaviour. Any thoughts ? Even -- Spatialys - Geospatial professional services http://www.spatialys.com
