  * the compiled version for linux is for 32 bit so it needs to be recompiled. A simple ''make'' in the ''src'' directory uses ''pd-lib-builder'' to build
  * after ''make'' there will be two ''.pd_linux'' files which need to be combined: ''g++ -static-libgcc -static-libstdc++ -shared -W -o helmholtz~.pd_linux helmholtz~.o Helmholtz.o''
