You're using a version of libsigc++ which is different from the one we use. You can find the full list of dependencies used for nightly builds and for releases at http://nightly.ardour.org/ Ardour is *not* written in C++11. We use a variety of compilers (gcc4, gcc5, clang, apple gcc). On Wed, Apr 20, 2016 at 12:13 AM, Ben Simons <[email protected]> wrote: > Hi, > > > *first timer here.
