#  fbp - The missing parser for FastBasic
#
#  Simple makefile, the only requirement is a C++17 compiler.
#
#  To cross-compile (for example to Windows), set CXX to the cross compiler
#  and EXT to the executable extension, the embed tool is built with HOSTCXX:
#
#    make CXX=x86_64-w64-mingw32-g++ EXT=.exe
#

CXX ?= c++
HOSTCXX ?= $(CXX)
EXT ?=
CXXFLAGS ?= -O2 -Wall
CXXFLAGS += -std=c++17
LDFLAGS ?=
