[postgis-devel] ST_Transform doesn't need Proj support?

[Obe, Regina]

I thought that, but thought I would put it in anyway.  I suspect some
people may be looking at the 1.4 docs for 1.3 support since the
documentation on 1.4 is much better than 1.3.

Thanks,
Regina

Yes it does, although it appears the check for this is in the source 
code rather than in the .sql file:


#ifndef USE_PROJ

PG_FUNCTION_INFO_V1(transform);
Datum transform(PG_FUNCTION_ARGS)
{

         elog(ERROR,"PostGIS transform() called, but support not 
compiled in.  Modify your makefile to add proj support, remake and 
re-install");
         PG_RETURN_NULL();
}

#endif


Incidentally I've just noticed that you've also committed the changes 
about PostGIS requiring PROJ.4 support to SVN trunk. I wouldn't worry 
about this, since PROJ.4 and GEOS are compulsory dependencies for 1.4 
(i.e. configure won't let you continue until you have installed both of 
them).


ATB,

Mark.
