[postgis-users] How can I update proj4 without recompile

[Regina Obe]

Guido,

 

1)      Have you already installed proj 4.9?  If so do you know what the libproj.so … is called?

2)      Which faulty areas are you getting, you have an example of such a query.  I fear that may be one of those bugs that is only fixable if PostGIS knows it is working with proj 4.9. Just want to rule that out.

 

 

Thanks,

Regina

Subject: [postgis-users] How can I update proj4 without recompile

 

Hey folks,

 

I am trying to update the proj4 libraries on my postgis because I think the older version of proj4 is giving me faulty areas (known bug). I would like to go from 4.8 to 4.9.

 

In talking to some friends I found out that I can make a sym link from the existing proj4 to a newly compiled proj4 without an issue. But, I can't seem to figure that out completely and need a little help.

 

# Here is what is running on my system:

 

select version();

    PostgreSQL 9.5.10 on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4, 64-bit

 

select postgis_full_version();

    POSTGIS="2.3.3 r15473" 

    GEOS="3.4.2-CAPI-1.8.2 r3921" 

    PROJ="Rel. 4.8.0, 6 March 2012" 

    GDAL="GDAL 1.10.1, released 2013/08/26" 

    LIBXML="2.9.1" 

    LIBJSON="0.11.99" 

    RASTER

 

# here is what I have done so far:

 

- locate the directory of the postgis

    pg_congif --pkglibdir

- get information about what libraries are associated with postgis

    ldd postgis-2.3

        libproj.so.0 => /usr/lib/libproj.so.0 (0x00007ff19e1dd000)

 

# this is where I loose the thread

 

I don't know if when I make install if there should be a file I need to link here?? Yeah I need a clue and would be grateful for any assistance on this.
