[postgis-users] OSX Server (Lion) linking failures on i386 architecture

[Jerry Carter]

I'm trying to compile PostGIS 1.5.3 and getting tripped up with 32 vs. 64 bit.  Following the normal process,

	cd postgis-1.5.3
	./configure
	make

compilation proceeds but the link fails.

	ld: warning: ignoring file ../liblwgeom/liblwgeom.a, file was built for archive which is not the architecture being linked (i386)

On the linking step, I noticed that the architecture flags specify both 32 and 64 bit, i.e. "-arch x86_64 -arch i386", but can't figure out how to disable 32 bit.  I've already rebuilt Proj.4 4.7.0 and GEOS 3.2.2 as hybrid 32+64 bit libraries.

Any suggestions to either disable 32-bit entirely for PostGIS or to get the makefiles to build liblwgeom as a hybrid?  Thanks much.

 P.S. I am using GCC version 'i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1' which is shipped with Xcode 4.2.
