cannam@154: # This GNU Makefile fragment is intended to be included from the
cannam@154: # Makefile for a Piper adapter, for use when recompiling an existing
cannam@154: # Vamp plugin (in C++) into a Javascript module.
cannam@154: #
cannam@154: # This fragment defines all of the actual build targets for the
cannam@154: # module. Your including Makefile should define some or all of the
cannam@154: # following variables before including it:
cannam@154: #
cannam@154: # MODULE_SOURCE - The name of the .cpp file for the module main entry
cannam@154: # point, e.g. vamp-example-plugins.cpp. You must write this file; it
cannam@154: # is not the same as the plugin library entry point used for the
cannam@154: # original Vamp plugin build. You can use the generator program (in
cannam@154: # piper-vamp-js/generator) to generate a preliminary version based on
cannam@154: # metadata reported by your actual plugin library, but it will usually
cannam@154: # still need some editing.
cannam@154: #
cannam@154: # MODULE_NAME - The name of the target feature extraction module.
cannam@154: # Typically a camel-cased representation of the Vamp plugin library
cannam@154: # name, like VampExamplePlugins.
cannam@154: #
cannam@154: # PLUGIN_SOURCES - All C++ source files for the plugin library.
cannam@154: #
cannam@154: # PLUGIN_C_SOURCES - Any C source files for the plugin library.
cannam@154: #
cannam@154: # DEFINES - Any additional -D flags for the C/C++ compiler.
cannam@154: #
cannam@154: # INCLUDES - Any additional -I flags for the C/C++ compiler.
cannam@154: #
cannam@154: # EMFLAGS - Any additional Emscripten-specific flags to pass to the
cannam@154: # compiler.
