[postgis-users] Error when building from source on mac os x 10.6

[William Kyngesburye]

It looks like the different parts of postgis compilation (ie most of it comes from the Postgres make system) don't have the same information about what architectures to compile for.

I always specify these before configuring postgis:

export CFLAGS="-Os -arch i386 -arch x86_64"
export PG_CPPFLAGS="-arch i386 -arch x86_64"
export SHLIB_LINK="-arch i386 -arch x86_64"
export LDFLAGS="-arch i386 -arch x86_64"

Note that you need to know which architectures GEOS, PROJ and Postgres are compiled for.  Use as many -arch flags in each of the above exports as is common to these.  It may be i386 and x86_64, but it could also be only x86_64.  If i386 is the only common arch, you should recompile to get at least x86_64.
