There is a problem with libsigc++-2 in ardour which includes an empty file (maybe due to a API change in libsigc++). I attach a patch that solves the problem by including the correct file. Reproducible: Always
Created attachment 149410 [details, diff] ardour fix for libsigc++-2
Oops, wrong herd :)
which version of libsigc++ are you using ? Here I have: /usr/include/sigc++-2.0/sigc++/slot.h with dev-libs/libsigc++-2.2.2 and ardour compiles fine. Can you paste an error ?
