#44 Unable to build with faust 2.5.21

[David Runge]

I'm trying to build with faust 2.5.21 (which I just moved to Arch Linux' main repositories).
After switching all (afaics) relevant python scripts to be explicitely python2, the build still fails:

This looks more like a python issue (in regards to changes in faust) to me, but maybe building with faust is also not relevant anymore?

That's a problem with our faust wrapper script. Currently acceppted faust version is 0.9.90, eg. faust1.
To use a other version you need to expicitly set the --faust flag, which is, by the way, a developer only flag. (use faust even if the installed version is not 0.9.90)

For distribution purpose you ain't need to rebuild the faust to cc files. All sources comes prebuild as C++ source files. The faust files been included for education purpose.

So, faust, is a essential part of guitarix development, but, you ain't need it to build guitarix from source.

As we moved on to faust version 2.15.11, I gues this one could be closed now.
