liblwgeom depends on SFCGAL

[robe]

Is there a reason why my liblwgeom-2.dll now depends on SFCGAL. I recompiled SFCGAL the way I normally do and then shp2pgsql started complaining about can't find SFCGAL.

I mean it doesn't depend on GDAL, why must it depend on SFCGAL?

What's in ./liblwgeom/Makefile ? is it linking it really?

Yes I presume this line in my Makefile does it:

ifeq (sfcgal,sfcgal)
CFLAGS += -I/projects/CGAL/rel-sfcgal-1.1.0w64gcc48/include -DHAVE_SFCGAL
LDFLAGS += -L/projects/CGAL/rel-sfcgal-1.1.0w64gcc48/lib -lSFCGAL
SA_OBJS += lwgeom_sfcgal.o
endif

It definitely is linking because I checked my liblwgeom with dependency walker and it has a dependency on SFCGAL.

it looks like liblwgeom/Makefile.in is explicitly requesting linking to it, but LDFLAGS has a -no-undefined to avoid linking to it. I guess we can just completely avoiding to link to it instead.

[strk]

actually no, we cannot do w/out it as liblwgeom does use SFCGAL (ptarray_from_SFCGAL etc). I guess you didn't notice before because you were building with no SFGAL ?

Okay I'll close this out as a won't fix then.
