faust2bela results in errors when building render.cpp

anton · Apr 11, 2019

Hi,
I followed this guide to run Faust code on Bela. Unfortunately when I run faust2bela -tobela simpleFX_Analog.dsp I get a bunch of compiler errors.
Bela image: v0.3.6b
Faust version from the guide, so 09ad59955eccb522382d60d58fb648e9b0fb4a78

Am I doing something wrong? Thanks in advance.

Compiler output:

Hmm are you 100% sure you are running the correct version of Faust? Note that it's not enough to have it checked out and running that command within it: you must actually make install it.

anton · Apr 11, 2019

I've also tried to upload render.cpp I got from https://faust.grame.fr/tools/editor/ and I got the same errors, so my local Faust is maybe not the cause. I will try to flash the sd again, maybe I messed it up while trying to set up distcc. I had it working before with some older Bela image and just recently updated to v0.3.6b.

giuliomoro · Apr 11, 2019

it's not about the image, I am sure: the faust-generated file is supposed to be self-contained except for some system-wide headers, but in your case you are not missing an #include'd file, but there is a type that is not defined in the file.

The file you'd get from the online editor will probably be the latest release (i.e.: not 09ad59955eccb522382d60d58fb648e9b0fb4a78).
And I confirm that with 09ad59955eccb522382d60d58fb648e9b0fb4a78, faust2bela -tobela simpleFX_Analog.dsp works fine.

Right, so now I downloaded the latest commit of Faust from master-dev, and I get the same error as you. If I run faust2bela with -soundfile it works. Created issue upstream: https://github.com/grame-cncm/faust/issues/310 .

Possible fix on Faust master-dev branch: https://github.com/grame-cncm/faust/commit/ff79a83d7b112779d1c2476a84120c48017ca67d

giuliomoro yes, you are right! with 09ad59955eccb522382d60d58fb648e9b0fb4a78 it works fine. My stupid mistake was that I just copy-pasted instructions from the guide without paying attention and there cd faust and git checkout are in wrong order:

git clone https://github.com/grame-cncm/faust.git &&\
git checkout 09ad59955eccb522382d60d58fb648e9b0fb4a78 &&\
cd faust &&\
make -j4 &&\
sudo make install

Thanks a lot for the help!

anton cd faust and git checkout are in wrong order:

I see, but then the command chain should have failed, given how they are chained with && that should only execute the next one if the previous one succeeds. Anyhow, I fixed the wiki now, thanks.
