Installation on macOS?

[jordan-brough]

What are the installation requirements for installing this gem on macOS?

I don't have any Firebird apps or libraries installed already on my machine so far. I'd like to keep local installs to a minimum as much as possible. I'm connecting to Firebird on a remote machine via a tunnel.

When I run gem install fb I get fatal error: 'ibase.h' file not found:

gem install fb  
Building native extensions. This could take a while...
ERROR:  Error installing fb:

@jordan-brough you still need to install Firebird client libraries and ibase.h headers are still needed to compile the gem even if the Firebird server is remote
