v.external compile error --without-gdal --with-postgres

[Papillon81]

The module v.external gives a compile error when compiling GRASS 7.0.1 --without-gdal --with-postgres.

The following error shows up: main.c:27:21: fatal error: ogr_api.h: No such file or directory

It seems like the ogr_api.h header should be conditionally included in the main.c file or the v.external module should not be compiled at all when gdal is disabled.

The GDAL library is a requirement (see https://grass.osgeo.org/grass70/source/REQUIREMENTS.html)

Why would you want to compile GRASS GIS without GDAL?

[Papillon81]

I saw that, yes. Why does GRASS offer a compile-time switch then? ;)

[neteler]

I think in is unavoidable for being able to set a path:

  --with-gdal[=path/gdal-config]
                          enable GDAL/OGR support (gdal-config with path,
                          e.g. '--with-gdal=/usr/local/bin/gdal-config')

I am unable to reproduce this error in relbr70 with --without-gdal --with-postgres. It's compiled fine. BTW, I fixed some related issues in r66591.

Should be fixed in r66597, backported to relbr70 as r66598. Closing, feel free to re-open if needed.
