[postgis-devel] Failing check_gdal test

[Raúl Marín Rodríguez]

Hi there,

>From a long time I've had issues with the `check_gdal` test as it seems to
be
expecting gdal to not be configured if you unset `postgis.gdal_datapath` and
print something about "GDAL_DATA".

I've tested with PG 9.6, 10.1 and 11 and postgis 2.4 and trunk with the same
diff as my machine doesn't fail the configuration test
(rt_util_gdal_configured).

I'm attaching some of the tests I've made. Does anyone have a similar
problem or know how to avoid failing that test (besides manually removing
it)?

Regards,
