[gdal-dev] GDAL2 and libgdal.so.1

[Sergio Segala]

Hi,

i've compiled GDAL 2 (2.0.1) for my CentOS7 environment. On the same 
machine I try to install postgis2 (2.1) from the official PostgreSQL 
repository (pgdg), but the yum package system said that I need the 
libgdal.so.1 library which is not present on the system.
So I'd a look to the /usr/lib64/ and the files I have there are: 
libgdal.so and libgdal.so.20 which are symlink to libgdal.so.20.0.1 and 
of course the bynary file libgdal.so.20.0.1, but there is not the 
libgdal.so.1 file or link. The same situation is on some Fedora RPM I 
downloaded for test pourpose.

So the question is: Is possible to install the RPM of PostGIS2 with the 
building of GDAL2 (I mean without recompiling PostGIS2 package)?
If yes, the right way to do that and also to have a stable system is to 
create a symlink named libgdal.so.1 to libgdal.so.20.0.1?
If no, is there a way to have GDAL 1.11 and GDAL2 on the same system?

Thanks,
Sergio
