Hi All.
If useful, I have resolved some OM audio initial problems in the following way. I must premise that I have just updated my Linux workstation to Fedora 28 distro. I have installed OM last version by the rpm file on ircam forge site, but I had problems on audio, similar to above mentioned ones. So I have donwloaded the omaudiolib project from Jean’s above address and compiled on my system: only digitized ‘make’ in terminal in the right directory and installed missing libraries requested for compilation. They were reported in error messages during first compilation attempts. Finally I have make a backup of the /usr/share/openmusic/resources/lib/linux/OMAudiolib.so (to be sure…) and then copied the new compiled OMAudiolib.so inside /usr/share/openmusic/resources/lib/linux. Of course with root privilegies.
I have not deeply tested everything, but it seems to run. On Ubuntu it should be the same procedures, maybe some directory could be different, I am not very acquainted with Ubuntu.
Ciao
