The ardour ebuild lacks a dependency for alsa. I had to emerge alsa-lib-1.0.14a-r1 for ardour compilation to work. The problem is known at ardour forum: http://ardour.org/node/1154 the compilation will fail with: libs/midi++2/alsa_sequencer_midiport.cc:175: error: 'SND_SEQ_PORT_TYPE_SOFTWARE' was not declared in this scope Reproducible: Didn't try Steps to Reproduce: 1. Install "old" alsa-lib (sorry, don't remember version) 2. emerge =ardour-2.0.5 3. Actual Results: compilation failed Expected Results: compilation succcedes
May I suggest that you upgrade your system properly, using --deep?
should be fixed now, thanks for the report
