So, this is a bug in libsigc++ however filing a bug isn't going to help because it's been fixed for ages. The error Hans points out is due to the fact that the ardour build is using the internal libgsigc++ which is version 2.0.6. We ship v 2.2.2 which is not affected by this problem... so using system includes will fix the problem from comment 1. That said, there are still a bunch of other errors that need fixing (missing #includes)
Created attachment 301396 [details] ardour 2.2 missing #includes
Created attachment 301397 [details] ardour 2.4 missing #includes I also noticed that ardour 2.4 was out and this patch would do it for 2.4 (same as the previous, however needs an additional file patched)
Created attachment 301398 [details] ardour spec patch This uses system libraries and the necessary BuildRequires for my system. I may be missing an additional one or two though, as I only built locally and not in mock.
Christopher, thanks for the patches! Since the libs included with ardour fail to build with gcc-4.3, and this has long been fixed in the system versions of these libs. We are now switching to using system libs, I didn't did this in the past because I felt this went against upstreams wishes, but considering the discussion in bug 339391, I assume upstream won't have any big problems with this. Thus, ardour-2.4-1, which is built against system libs and includes Christopher's patches to build with gcc-4.3, is on its way to rawhide. I also send the gcc-4.3 and various other patches we've been sitting on (bad us!) upstream.
