@DanH Yeah, i have sometimes trouble with the web IDE too, no examples, doesn't recognize my audio card, etc.
Just try hit F5 a couple of times to refresh the website, most of the time it worked for me
@etXzat Yes Ubuntu has some quirks when it comes to installing some packages, that is why I build from source and installed in manually.
I want to avoid installing from the official repository since they have outdated versions, see: https://launchpad.net/ubuntu/+source/faust
latest current stable is 2.41
@sletz
make all && sudo make install solved my issues! Thank you very much.
