Can't link with libspatialite-4.3.0 if GEOS is disabled (gaiaCreateDxfParser is undefined)

[Francois Birot]

Hi there,

I just compiled libspatialite for iOS without GEOS (in order not to have issues with the LGPL license that is problematic with iOS). Yet I get the following error when trying to link with the compiled library:

 

Undefined symbols for architecture arm64:

  "_gaiaCreateDxfParser", referenced from:

      _load_dxf in libspatialite-nogeos.a(libsplite_la-spatialite.o)

ld: symbol(s) not found for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

The problem is that, the load_dxf function that was added in libspatialite 4.3 (in spatialite.c) is not in a #ifndef OMIT_GEOS / #endif block while it uses functions (gaiaCreateDxfParser) that are only defined (in dxf_parser.c) if OMIT_GEOS is not set.

Hi Framcois,

yes, I confirm: this issue: it's now definitely fixed in the Fossil repository
and we'll distributed with the next release (presumably not before  the
end of this summer).

it's a real pity that your bug report was submitted immediately after releasing
4.3.0 "stable": if it had been promptly submitted in the previous two weeks
during the Release Candidate refining steps we'll now have a 4.3.0 immune
from this minor glitch,
the intended scope of Release Candidates community testing in exactly the
one to identify and resolve stupid issues like this *before* and not *after*
actually releasing --- it will be for the next time ;-)

bye Sandro

That’s indeed a pity, but thanks anyway for fixing it Sandro !
