Makefile

# CREDDIT MAKEFILE
#
# Normal usage: make; make install
#
# 'make' will default to compiling creddit in ./build/creddit and libreddit as
# ./build/libreddit.so (shared object)
# To compile libreddit as a shared library separately, use 'make libreddit'
#
# To compile libreddit as a static library, compile with STATIC=y
# Ex. make STATIC=y
#
# To turn on debugging, set an environment variable called 'REDDIT_DEBUG' to
# 'y' and then 'make clean' and 'make'. This will turn off optimization, turn on
# the -g flag, and set the 'REDDIT_DEBUG' C macro for all of the project's C
# files.
#
# Bash users can run the command 'export REDDIT_DEBUG=y' to turn debugging on.
#
# You can also compile individual parts or individual files on their own, by
# specifying their object name.
# Ex. 'make build/src/main.o'
