@d-healey Oh it looks like someone called Chrisboy2000 posted a workaround on the JUCE forum - https://forum.juce.com/t/dsp-module-breaks-compilation-on-linux/27346/3 :)

And here is the commit that implemented it. https://github.com/christophhart/HISE/commit/b1a3afff06d3b16f58723d3041449522c8dbb17e

I'll push this on my fork
