the compiler is complaining about not finding faust/dsp/llvm-c-dsp.h. but the correct header is named faust/dsp/llvm-dsp-c.h it seems that the name changed for some reason, since the first comment line in https://github.com/grame-cncm/faust/blob/master-dev/architecture/faust/dsp/llvm-dsp-c.h /************************** BEGIN llvm-c-dsp.h **************************/ mentions the former name.
editing the include in mephisto.c has solved this issue.
The header has been renamed to llvm-dsp-c.h (for naming coherency reasons accros the code base). You'll have to adopter the mephisto.lv2 source code for that.
