Re: earthdistance

Is there not a precompiled Postgis package you can use?

There are a few dependencies, the PROJ.4 libraries you are missing enable projection support, and the package tools
automaticallymanage such dependencies. I know packages are well supported for Debian, Ubuntu/Mint/etc, Suse & Fedora. 

See: http://trac.osgeo.org/postgis/wiki/UsersWikiInstall

As a simple potential user, I tried to install PostGIS, downloaded all libraries required: proj-4.8.0,
gdal-1.10.0,json-c,postgis-2.0.3,geos-3.3.8,libwml2-2.9.0,and tried to build the first library with the simple
procedure:

./configure
make
make install

I had a fatal error:

make[2]: entrant dans le répertoire « /home/olivier/ob/proj-4.8.0/src »
/bin/bash ../libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -DPROJ_LIB=\"/usr/local/share/proj\"
-DMUTEX_pthread    -g -O2 -MT jniproj.lo -MD -MP -MF .deps/jniproj.Tpo -c -o jniproj.lo jniproj.c 
libtool: compile:  gcc -DHAVE_CONFIG_H -I. -DPROJ_LIB=\"/usr/local/share/proj\" -DMUTEX_pthread -g -O2 -MT jniproj.lo

jniproj.c:52:26: fatal error: org_proj4_PJ.h: No such file or directory
compilation terminated.

problem out of the scope of this list, and probably not /difficult. Since I look for a simple geographic indexing using
impreciselat,long coordinates that do not deal with precise modeling; that I am afraid of long install procedure, and
heavycomputations, I also give up. 

Spacial mysql indexing seems to be included in pre-built packages.

What can we do?

You might install Postgis to implement very powerful spatial functionality that can easily do what you are asking (plus
awhole lot more). 


indeed, PostGIS is the logical answer, but the OP specifically stated he wanted the functionality without
'sophisticatedgeographic systems'.  so I ignored the question. 

the alternative would be implementing your own spherical geometry functions, and hook them up to GiST indexing, its not
thathard, but by the time you got all the functionality you need, you'd be half way to PostGIS, so why fight it?
