1st needed to add "-std=c++11" to CXXFLAGS in Makefile
2nd I got "main.cc:(.text.startup+0,254): undefined reference to 'Imidi_alsa::Imidi_alsa(Lfq_u32*, Lfq_u8*, unsigned short*, char const*)'
Copy stops to /usr/share/aeolus cp -r stops /usr/share/aeolus/
Run aeolus
Save
Restart aeolus
Segmentation fault
It seems to be an attempt to read the default wave files (*.ae0) that triggers the fault. Replacing these with original ones stops the fault but then shows error: "Presets in file '/root/.aeolus-presets' are not compatible". It is as if the ae0 files differ from what the source / preset config expects.
