Hello,
Going through the browser/external/abclib example patches, faustgen2~ fails to load due to ma.deg2rad in the dsp code.
This doesn't appear to happen with other faust patches, so may be related to abclib more than faustgen2~
It often happens with abc_2d_decoderN.dsp, which throws the error:
faustgen2~: abc_2d_decoder3.dsp : 56 : ERROR : undefined symbol : deg2rad
