Centos 7, unixODBC, psqlodbc - problem finding .so-file

[stephan0h]

So - I'm a total newbei to brew - just so you know, if I say something dumb ...

My general goal is: I've got an Oracle dabase running on Centos 7 and I want to connect it to a PosgreSQL Database on another machine by means of ODBC. Using brew because I wanted to use newer versions of the ODBC-stuff ...

So, I installed brew, then I did:

brew install gcc
brew install unixODBC
brew install psqlodbc

All went fine. Then I looked into configuration of the whole thing and I got stuck with a file-not-found error. Straight out of the log file:

But the file '/home/linuxbrew/.linuxbrew/lib/psqlodbcw.so' is there.
So I googled a bit and somebody mentioned ldd. This is what I did:

So there are things it's looking up in linuxbrew - others somewhere else. Is this good? Is this bad?

So, what's missing? Is there a problem with my configuration that I can fix? Am I looking in the wrong direction? Don't know ...
Any hints are very appreciated!

Solved this outside of brew - so this is no more relevant ...
