mako.mk

# Makefile for compiling the Mako Server for Linux
# Example: make -f mako.mk EPOLL=true
# The above compiles mako using the 'epoll' socket dispatcher. The
# default is to use the 'select' socket dispatcher.

# The makefile is designed for the "Embedded Linux Web Based Device
# Management" tutorial and will auto include the generated Lua
# bindings if found. The makefile will also auto include SQLite, Lua
# Protobuf, CBOR, and LPeg if found. LPeg can be installed as follows:
# wget http://www.inf.puc-rio.br/~roberto/lpeg/lpeg-1.0.2.tar.gz
# cd src
# tar xvzf ../lpeg-1.0.2.tar.gz
# mv lpeg-1.0.2 lpeg
