Makefile 



# Variables to override

#

# CC            C compiler

# CROSSCOMPILE	crosscompiler prefix, if any

# CFLAGS	compiler flags for compiling all C files

# ERL_CFLAGS	additional compiler flags for files using Erlang header files

# ERL_EI_LIBDIR path to libei.a

# LDFLAGS	linker flags for linking all binaries

# ERL_LDFLAGS	additional linker flags for projects referencing Erlang libraries



# Look for the EI library and header files

# For crosscompiled builds, ERL_EI_INCLUDE_DIR and ERL_EI_LIBDIR must be

# passed into the Makefile.
