0.45.0: Build failure due to missing dsp.h

[dvzrv]

Hi! 👋

When building 0.45.0 from source I ran into an issue with a header file that can not be found:

My assumption is, that this is supposed to find /usr/include/faust/dsp/dsp.h but somehow doesn't.

Do you still build the old ladspa plug? Please, don't do that. We've now the vst3 plug here https://github.com/brummer10/guitarix.vst which serves much better then this old dinosaur.

I must admit that I haven't checkout if the old ladspa build, and as it seems it doesn't.
Time to remove it.

[brummer10]

I forgot to mention, this "dsp.h" file is part of the Neural Amp Modeler which I indeed haven't include into this old ladspa plug, while it use the same source as the main app, it fail to build.
However, as I said, please remove the ladspa plug as with the next release I'll remove it completely from the source.

Ah, good to know! Will do! (and yes time to drop ladspa...)

[dvzrv]

Removing the --ladspa and --new-ladspa waf options resolves this issue.
