[postgis-users] [GENERAL] Error During PostGIS Build From Source on Linux

[Osahon Oduware]

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.
