[GRASS-dev] GDAL,GRASS 7 and PostGIS on Ubunutu 12.04

Thanks for your feedback.
I had read ticket #2953 and found it a bit confusing in that sense that Martin modified GDAL (and not the plugin). The plugin (on http://download.osgeo.org/gdal/) was last modified 05-Aug-2007. To me it seems that GDAL is now (with Martins fixes in place) using a mixture of GRASS 6 and 7 libs. GDAL itself does not complain (if both GRASS versions can be found) but raster2pgsql does (and maybe OGR would as well)...
libgrass_I.so is GRASS 6 specific right? So after I compiled GDAL (not the plugin) against GRASS 7 it should not use that library at all?
And the message that the GISBASE /usr/local/grass-7.0.svn was used (see below) indicates that GDAL somehow operates based on GRASS 7.
So I went back to GRASS 6 support in GDAL (which is OK for raster data).
Out of curiosity I copied this section:
AC_CHECK_LIB(grass_gis,G_is_initialized,GRASS_SETTING=grass70+,GRASS_SETTING=no,-L$with_grass/lib -lgrass_raster -lgrass_imagery -lgrass_vector -lgrass_dig2 -lgrass_dgl -lgrass_rtree -lgrass_linkm -lgrass_dbmiclient -lgrass_dbmibase -lgrass_gproj -lgrass_gmath -lgrass_gis -lgrass_datetime)
if test "$GRASS_SETTING" != "no" ; then
if test "$GRASS_SETTING" = "grass70+" ; then
G_VECTLIBS="-lgrass_vector -lgrass_dig2 -lgrass_dgl -lgrass_rtree -lgrass_linkm -lgrass_dbmiclient -lgrass_dbmibase"
LIBS="-L$with_grass/lib $G_VECTLIBS $G_RASTLIBS -lgrass_gproj -lgrass_gmath -lgrass_gis -lgrass_datetime $LIBS"
G_VECTLIBS="-lgrass_vect -lgrass_dig2 -lgrass_dgl -lgrass_rtree -lgrass_linkm -lgrass_dbmiclient -lgrass_dbmibase"
LIBS="-L$with_grass/lib $G_VECTLIBS $G_RASTLIBS -lgrass_gproj -lgrass_vask -lgrass_gmath -lgrass_gis -lgrass_datetime $LIBS"
>From GDALs configure to the configure.in in the plugin. Then , after "autoreconf --force --install" the plugin compiles using GRASS 7. However "make" of course still references grass57+ code...
Looks like both GDAL and the GRASS-GDAL plugin need some update...
Shall I add an error-report to ticket #2953?

I don't think that GDAL is already compliant with GRASS 7:

I guess the order should be reverse.

... for me surprising :-)

IMHO the GDAL ticket should be fixed.
