[LAU] fltk linking problem

Over the last few weeks I've been going through Yoshimi with a fine-tooth comb bug hunting, with some success (and much frustration). I'm doing this on my 'office' computer which is running debian testing on a 64bit AMD - fairly similar to my music machine. During the week, I did an update via synaptic and now suddenly when I try to compile Yoshimi it fails to link, giving the message: Linking CXX executable yoshimi /usr/bin/ld: /usr/lib/x86_64-linux-gnu/libfltk.a(Fl_x.o): undefined reference to symbol 'dlsym@@GLIBC_2.2.5' /lib/x86_64-linux-gnu/libdl.so.2: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status make[2]: *** [yoshimi] Error 1 make[1]: *** [CMakeFiles/yoshimi.dir/all] Error 2 make: *** [all] Error 2 will@debian:~/yoshimi_20130926/src$ The investigating I've done suggests that something has changed in cmake so that yoshimi now needs a more 'correct' identification of fltk. I sort of gathered that cmake.txt was the place to look, but doing so tells me nothing. fltk is there but none of the information really makes sense to me. Although I don't like doing anything experimental on my music machine, I can do that for the time being as it is running an earlier version of the distro but presumably the new requirement will eventually hit the stable releases. Can someone help me sort this out please. P.S. A current version of ZynAddSubFX doesn't have this problem, but the build structure is now very different so I couldn't find any points of comparison. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
