# Makefile for marsond. Should be fine with any make (GNU, BSD, etc).

# Remember, all these assignments, you can override on the make
# command line rather than editing this file. Examples:
# make CC=clang CFLAGS=-O3
# make install PREFIX=/usr/local

### Project information.
PROJ=marsond
VERSION=0.1.1

### Compiler and options.
CC=gcc
# CC=clang works, too

COPT=-O2
CWARN=-Wall
CFLAGS=-std=c99 $(COPT) $(CWARN) -DVERSION='"$(VERSION)"'

### Install paths. Not compiled into the binary.

# These are appropriate for Slackware. Most other distros will need
# MANDIR=$(PREFIX)/share/man, and DOCDIR=$(PREFIX)/share/doc/marsond.
PREFIX=/usr
SBINDIR=$(PREFIX)/sbin
MANDIR=$(PREFIX)/man
MAN8DIR=$(PREFIX)/man8
DOCDIR=/usr/doc/$(PROJ)-$(VERSION)
UDEVDIR=/etc/udev/rules.d
