Please use the issue trackers there to report any bugs that you find, thanks!
The architecture files and helper scripts are also included in the latest Faust git sources, so if you keep your Faust installation up to date, chances are that you already got them.
Both architectures are now also available through the Faust online and remote compilers, thanks Yann! So you can give them a try immediately without having to install anything. Simply head over to
http://faust.grame.fr/onlinecompiler/, drop one of the dsp examples provided in the faust-lv2|vst Bitbucket repositories or your own Faust sources there, choose one of the linux lv2 or vst architectures as target and go to the Exec tab to receive your freshly baked plugin.
If you can make it to Berlin, I'll be showing both faust-lv2 and faust-vst there in the main hall of c-base on Saturday (April 9) at 3 p.m., would be nice to meet you there!
Enjoy! :)
