Minimake

Minimake is a small project written in about a week in C99. Its goal was to reproduce the main features of the well known GNU Make utility.

Note

This is a school project, therefore it probably won't interest you if you are looking for something useful.

Build

make

or even better

minimake

How it works

If you're not familiar with Make, what it does is that it reads a file named Makefile in the current directory which contains instructions to build a project in the form of recipes. It includes support for variables, dependencies , implicit rules and more.

Then depending on the user input it automatically executes a recipe with its dependencies.

Here is what a basic one can look like

BENCH_FLAGS = --all

test_and_bench:
  bash ./runtests.sh
  bash ./runbenchs.sh $(BENCH_FLAGS)

But it will more realisticly look like that

CC = gcc
CFLAGS = -std=c99 -pedantic -Werror -Wall -Wextra -Wvla
LDFLAGS=

DBG_CFLAGS = -fsanitize=address -g
DBG_LDFLAGS= -fsanitize=address


SRC_DIR = src
LIB_SRCS = lines/lines.c hash_maps/hash_maps.c lists/lists.c files/files.c
MAIN_SRCS = main.c minimake.c

SRCS = $(MAIN_SRCS:%=$(SRC_DIR)/%) $(LIB_SRCS:%=$(SRC_DIR)/%)
OBJS = $(SRCS:.c=.o)

TARGET= minimake
DBG_TARGET = minimake-dbg

$(TARGET): $(OBJS)
	$(CC) -o $@ $^ $(LDFLAGS) $(LDLIBS)
	@echo $(OBJS)

debug: CFLAGS += $(DBG_CFLAGS)
debug: LDFLAGS += $(DBG_LDFLAGS)
debug: $(OBJS)
	$(CC) -o $(DBG_TARGET) $^ $(LDFLAGS) $(LDLIBS)

check:
	dash ./tests/run.sh

clean:
	$(RM) $(TARGET)
	$(RM) $(OBJS)
