Inputs ######
SRC_DIR = "src"
Not working. Needs pathmap variables
CONFIG = ENV["CONFIG"] || "Release"
Arch-ABI-Configuration
ARCH = "x86"
ABI = "gnuabi"
AAC = [ARCH, ABI, CONFIG].join('-')
OBJ_DIR = File.join("build", AAC)
DIST_DIR = File.join("dist", AAC)
PROJ = "raketest"
DIST_EXE = File.join(DIST_DIR, PROJ).ext('exe')
CC
CC = "gcc"
C_SRCS = FileList["#{SRC_DIR}/\/*.c"]
def to_obj(objdir, f)
f.sub(/^#{SRC_DIR}/, objdir).ext('.o')
end
C_OBJS = C_SRCS.map { |f|
to_obj(OBJ_DIR, f)
}
Targets ######
CLEAN.include C_OBJS
CLEAN.include DIST_DIR

directory DIST_DIR
Create output dirs for each include dir
C_OBJS.each do |d|
directory d.pathmap('%d')
end
task :default => :build
desc "Build"
task :build => DIST_EXE
task :info do
p C_SRCS
