[gdal-dev] Failing to include libgdal.so on Fedora 32

[Matthys Kroon]

Thanks for your help.

I do seem to have the file. I have libpq and libpq5 packages installed.

/usr/lib64#ls -alh libpq.so*
lrwxrwxrwx. 1 root root   13 Aug 20 14:42 libpq.so -> libpq.so.5.12
lrwxrwxrwx. 1 root root   13 Aug 20 14:42 libpq.so.5 -> libpq.so.5.12
-rwxr-xr-x. 1 root root 1.3M Aug 20 14:42 libpq.so.5.12


I think it has something to do with the postgres version. All those
references have "@RHPG_9.6" which I assume references postgres 9.6. I also
have postgres 11 and 12 installed on the system (was developing postgres
apps in my previous job). I think somehow I have a later version of libpq
installed.

I'm going to try and verify that I have the correct version installed.
