<font size="+1">Hello<br>
<br>
I am trying to build GDAL with GEOS support on RHEL 6 (64-bit)
and am getting nowhere fast!<br>
<br>
I've been using the OGR api from gdal-1.11.1 for over a year
with excellent results and now need to use the geometry methods
that are only available with the inclusion of GEOS (else the
message ERROR 6: GEOS support not enabled").<br>
<br>
I've built geos-3.1.0 and the set the GDAL configure option
"--with-geos" to point to "geos-config". Initially this did not
work as gdal configure was attempting to execute "geos-config"
which did not have execute permission (doing a chmod 777 on
"geos-config" resolved this). <br>
<br>
GDAL builds fine and appears to partially recognize GEOS
availability but cannot confirm "GEOSversion" in geos_c. The
following two lines are output from gdal configure;</font><font
size="+1"><br>
<br>
checking for GEOS version >= 3.1.0... yes</font><font
size="+1"><br>
checking for GEOSversion in -lgeos_c... no</font><br>
<font size="+1"><br>
At this point it looked like a search issue so I've updated the
PATH and LIBRARY_PATH env vars to point to the geos "capri"
directory containing "libgeos_c.la". Still no luck. Have tried
copying libgeos_c.la to the gdal folder and /usr/local/lib but
still no luck. <br>
<br>
Going through the list I see where others have run across
similar but not the same problem. <br>
<br>

resolve this?</font><font size="+1"><br>

I've never come across problems like this with GEOS and GDAL. If
GEOS is in usual place (/usr/local/lib for example) GDAL configure
picks it up by default.<br>
<br>
It sounds a bit like you did not install GEOS. Did you issue "make
install" after building GEOS?<br>
