[postgis-users] Problems installing PostGIS on Red Hat EL 5

[Paragon Corporation]

Jeshua,

Thanks for the tip, but unfortunately that didn't work.

I verified that the geos-config was in /usr/local/bin/geos-config (and had a
new date on it) - (by the way I had 8.2.5 on this server before I blew it
out so not sure if that may be causing problems)

I reran the configure and make clean make install of Postgis with

./configure --with-pgsql=/usr/bin/pg_config  --with-geos=
/usr/local/bin/geos-config

It even gave me this nice screen (which I think it actually did before which
is why I though it was finding geos okay)

 SUMMARY
 -------------------------------------------------------

 HOST_OS: linux-gnu

   PGSQL: /usr/bin/pg_config
    GEOS: /usr/local/bin/geos-config (with C-API)
          (ldflags: -L/usr/local/lib)
    PROJ: prefix=/usr/local libdir=/usr/local/lib
   ICONV: 1

 PORTNAME: linux
   PREFIX: /usr
  EPREFIX: ${prefix}
      DOC: /usr/share/doc/postgresql/contrib
     DATA: ${datarootdir}
      MAN: ${datarootdir}/man
      BIN: /usr/bin
      EXT: /usr/lib/pgsql (\$$libdir)
 --------------------------------------------------

Then I restarted the Postgresql service with a 
service postgresql restart

Same issue.  Any other thoughts on the subject are welcome.

Thanks,
Regina

Hi Regina,

Looks like PostGIS needs to be linked against the Geos library.

When you run configure use the "--with-geos=" directive, and point it to the
full path of where "geos-config" is located. For example, if geos is
installed to /usr/local, the configure option might look something like
this:

	--with-geos=/usr/local/bin/geos-config

Hope this helps.
