Thanks everyone for your comments and suggestions. They were all very helpful, although the eventual solution proved to be ridiculously simple. Cal had constructed quite an involved build system with lots of options editable with ccmake. All I had to do was add -ldl to the build I was performing :o Having said that, what was initially quite frustrating was that some of the other things I tried (like directly editing cmake_cache) also worked, but being finicky about repeatbility I would then try to revert the changes, only to find it still linked! I couldn't find out where cmake stored this information but eventually hit on the idea of fetching several fresh copies, and renaming them as yoshimi_1 ... 2.... etc. So... I think I've got it sorted. There is a lot I still don't understand but some of the ideas are beginning to stick :) -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
