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 -MD -MP -MF .deps/jniproj.Tpo -c jniproj.c -fPIC -DPIC -o .libs/jniproj.o 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 imprecise lat,long coordinates that do not deal with precise modeling; that I am afraid of long install procedure, and heavy computations, I also give up. Spacial mysql indexing seems to be included in pre-built packages. What can we do? 2013/8/10 John R Pierce <pie...@hogranch.com> > On 8/9/2013 5:18 PM, Brent Wood wrote: > > You might install Postgis to implement very powerful spatial functionality > that can easily do what you are asking (plus a whole lot more). > > > > indeed, PostGIS is the logical answer, but the OP specifically stated he > wanted the functionality without 'sophisticated geographic 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 *that *hard, but by > the time you got all the functionality you need, you'd be half way to > PostGIS, so why fight it? > > > > -- > john r pierce 37N 122W > somewhere on the middle of the left coast > > -- Olivier Chaussavoine
