I'm not sure which interpreter is actually used, but I'm certain that
libfaust requires LLVM now.
This is how my build/backends/most.cmake file looks like:
"
set ( C_BACKEND OFF STATIC DYNAMIC CACHE STRING
"Include C backend" FORCE )
set ( CPP_BACKEND COMPILER STATIC CACHE STRING
"Include CPP backend" FORCE )
set ( FIR_BACKEND OFF STATIC DYNAMIC CACHE STRING
"Include FIR backend" FORCE )
set ( INTERP_BACKEND STATIC CACHE STRING
"Include INTERPRETER backend" FORCE )
set ( JAVA_BACKEND OFF STATIC DYNAMIC CACHE STRING
"Include JAVA backend" FORCE )
set ( LLVM_BACKEND OFF STATIC DYNAMIC CACHE STRING
"Include LLVM backend" FORCE )
set ( OLDCPP_BACKEND OFF STATIC DYNAMIC CACHE STRING
"Include old CPP backend" FORCE )
set ( RUST_BACKEND OFF STATIC DYNAMIC CACHE STRING
"Include RUST backend" FORCE )
set ( SOUL_BACKEND OFF STATIC DYNAMIC CACHE STRING
"Include SOUL backend" FORCE )
set ( WASM_BACKEND OFF STATIC DYNAMIC WASM CACHE STRING
"Include WASM backend" FORCE )
set ( DLANG_BACKEND OFF STATIC DYNAMIC CACHE STRING
"Include DLANG backend" FORCE )
"
And this is how I'm compiling faust:
"
VERBOSE=1 CFLAGS="$CFLAGS" CXXFLAGS="$CXXFLAGS"
CMAKEOPT="-DCMAKE_BUILD_TYPE=Release -DSELF_CONTAINED_LIBRARY=on
-DCMAKE_CXX_COMPILER=`which $DASCXX` -DCMAKE_C_COMPILER=`which
$DASCC`" make most
"
If I apply this patch first:

Is there anything else I need to do to get rid of LLVM? It's so
cumbersome editing cmake files that I don't really know where to
start.
