# Centre for Digital Music, Queen Mary University of London

## This Makefile is intended for use on the BeagleBone Black itself #
## and not for cross-compiling #
## available command line options: #
## EXAMPLE=             -- name of the folder in examples/ to be copied to projects/ and built
## PROJECT=             -- name of the folder in projects/ to be built
## CL=                  -- list of command line options to pass to the program when running
## CPPFLAGS=           -- list of additional flags passed to the C++ compiler
## CFLAGS=             -- list of additional flags passed to the C compiler
## COMPILER=            -- compiler to use (clang or gcc)
## LDFLAGS=                -- linker flags (e.g.: -L. ) 
## LDLIBS=                -- libs to link in (e.g.: -lm )
## AT=                  -- used instead of @ to silence the output. Defaults AT=@, use AT= for a very verbose output
## DISTCC=              -- specify whether to use distcc (1) or not (0, default)
## RELINK=              -- specify whether to force re-linking the project file (1) or not (0, default). Set it to 1 when developing a library.
