thanks, but the problem still persists. If I try make install then
"make: Nothing to be done for `install'."
So if I perform make clean and then make install and then try to attempt
to connect I get the same error.
ruby: symbol lookup error: /usr/lib/ruby/gems/1.8/gems/fb-0.5.9/./fb.so:

Which version of Firebird are you using and how did you install it?
Was it from the repository? Or from the rpm?
I have installed mine from the .tar.gz archive, and it created the
symbolic links for all the libraries in /opt/firebird/lib to /usr/lib
I know if you install from the repository (at least for Ubuntu), you
will need to install also firebird-devel.
Just a note that I get some warnings for make install too, eg. :
fb.c: In function ‘fb_error_check’:
fb.c:380: warning: passing argument 1 of ‘isc_sqlcode’ from incompatible
(I'm trying to connect like :
db = Database.new(
:database => "x.x.x.x:d:\\database\\tesdb.gdb",
:username => 'username',
:password => 'password')
conn = db.connect rescue db.create.connect
That seems to be ok, but the path should be /database/testdb.gdb. Are
you using interbase or firebird? Or is it just a habit from interbase
to give your database files a .gdb extension?
Anyway, try to check if you have the development libraries all in
place. When I first installed the fb gem, I had the same error you
did, but then I cleaned up all the fb libraries in /usr/lib and then
created the symbolic links by hand, and that solved my problem. But,
as I said, I installed from the .tar.gz archive on Ubuntu. Don't know
if the same will resolve your issue with CentOS, but I think it
Hope that helps you solve your problem.
