Re: Error During PostGIS Build From Source on Linux

Hi Adrian,

Thanks for your help so far. This is the output of the PostGIS
configuration:

-------------- Compiler Info -------------
C compiler: gcc -g -O2
SQL preprocessor: /usr/bin/cpp -traditional-cpp -w -P

-------------- Dependencies --------------
GEOS config: /home/nagispg/local/geos361/bin/geos-config
GEOS version: 3.6.1
GDAL config: /home/nagispg/local/gdal213/bin/gdal-config
GDAL version: 2.1.3
PostgreSQL config: /home/nagispg/local/pgsql/bin/pg_config
PostgreSQL version: PostgreSQL 9.6.2
PROJ4 version: 49
Libxml2 config: /usr/bin/xml2-config
Libxml2 version: 2.7.6
JSON-C support: no
PCRE support: no
PostGIS debug level: 0
Perl: /usr/bin/perl

--------------- Extensions ---------------
PostGIS Raster: enabled
PostGIS Topology: enabled
SFCGAL support: disabled
Address Standardizer support: disabled

-------- Documentation Generation --------
xsltproc: /usr/bin/xsltproc
xsl style sheets:
dblatex:
convert: /usr/bin/convert
mathml2.dtd: http://www.w3.org/Math/DTD/mathml2/mathml2.dtd

I had to install a *higher version of Proj (4.9.3)* that was used to
configure PostGIS (I think I read somewhere in the documentation that the
version of Proj should be >= 4.6.0). *Now, I get the following error when I
run CREATE EXTENSION postgis:*

*ERROR: could not load library postgis-2.3.so <http://postgis-2.3.so>:
libproj.so.12: cannot open shared object file: No such file or directory*

I would be glad if someone could point me to what I am doing wrong and
possible solution.
