Hello, thanks for the BT info!
No worries, it is all LGPL, I just left the two library builds in situ (possibly not intentionally!), but each is simply the result of building respectively in the "cdp2k" and "sfsys" directories. It should all build without fuss on a 32bit Linux, but as my only linux system is 64bit (Suse), I can't absolutely guarantee it. But making it work on 64bit architectures is the new thing, hitherto it has only been built on 32bit architectures anyway. I am currently testing a "proper" build system using CMake, created by John Fitch, and will post a new source release in a few weeks (because I am away for one of them). It will all eventually find a home on (probably) github.
