Hi everyone,

First let me say kudos to the Bela team for a wonderful product! I'm been enjoying my bela-mini for a couple of months now, primarily using belacsound, csound being my DSP language of choice.

I tried using the online faust editor to get some C++ code compiled last night. The source was from their own set of Bela examples, and I chose the Bela-MIDI-8 target: https://github.com/grame-cncm/faust/blob/master-dev/examples/bela/simpleSynth_FX_Analog.dsp

When on the bela-mini I got a compile error related to a "non-member static call" or something like that...(I will post the exact error later, as I am at work and not in front of my bela setup). Anyway, it wouldn't compile. This means the target code generator of Faust is broken, or it's targeting a different compiler or C++ standard, perhaps.

This brings up the general question: does anyone know definitively the quickest, easiest path at the moment for using Faust on Bela?

Regards,

AKJ

Yes, please paste the exact error message. Thanks.

Hi sletz, here is the error....render.cpp is here: https://www.dropbox.com/s/pgkme538xe8zriy/render.cpp?dl=0 (I originally tried attaching, but the upload to the forum proved too slow)

Thanks. Fix in progress.

Sletz, tnx...is the fix on the faust side, or the bela side?

    akjmicro but the instructions here still work, although probably without midi and osc, or whatever is broken on faust. The version connecting analog and digital i/o with and without the gui seem to work fine. The upcoming faust fix should fix the midi part

      Great...but alas, my main interest is getting MIDI to work: at the moment, I have no analog-in or digital-in hardware, nor time and interest to pursue it 😉
