Postgis Extension install PostgreSQL

Question

When I try to enable PostGis extension on my database I receive the following:

postgis=# CREATE EXTENSION postgis;
ERROR:  could not load library "/usr/pgsql-9.3/lib/rtpostgis-2.1.so": libhdf5.so.6: cannot open shared object file: No such file or directory

I used find -name to find the files:

[root@digihaul3-pc /]# find -name rtpostgis-2.1.so
./usr/pgsql-9.3/lib/rtpostgis-2.1.so

[root@digihaul3-pc /]# find -name libhdf5.so.6
./usr/lib64/mpich2/lib/libhdf5.so.6
./usr/pgsql-9.3/lib/libhdf5.so.6
./usr/lib/mpich2/lib/libhdf5.so.6

Which operating system are you running? You might find an answer here -- but without more details I can't advise further. — ProgrammerDan

That's unfortunate, I'm guessing you've found most of the other help I've seen which is that there appear to be issues installing in CentOS. However, this looks most useful and this may also help, although not about CentOS. Sorry I can't help further, I don't use CentOS much because of issues like this... — ProgrammerDan

it is for fordora 15. But i tried everything else and this actually fixed my issue and allowed me to install the postgis extentions. Doesn't take long to install.

Thinking Monkeys Post:

Checked for whether /etc/ld.so.conf has a reference to the path /usr/lib64/mpich2/lib.

by doing  ldconfig -p | grep libhdf5.

Which did not output anything.

On checking that /etc/ld.so.conf had  include ld.so.conf.d/*.conf.

Checked for the files in directory ld.so.conf.d. One of the conf file in include ld.so.conf.d was /etc/ld.so.conf.d/atlas-x8664.conf which contained /usr/lib64/atlas.

So I,

    created a file called gdal.conf in the directory ld.so.conf.d.
    Added the string /usr/lib64/mpich2/lib to the file.
    Ran ldconfig.
    Now, ldconfig -p | grep libhdf5 had the paths to llibhdf5 files.
    After doing the above, postgis raster support installation went smoothly.
