The repository https://github.com/alelievr/libft-unit-test is a great resource for automatically testing and benchmarking your libft library. This tutorial should help you with installing and using these tests.
- You should already have all the required files (ft_*.c, libft.h, Makefile) in your libft directory, even if your .c files or libft.h are empty.
- Your Makefile to create libft.a should already be working. I am not allowed to share working code here but what your Makefile should do is:
- Create .o files from your .c files
- Create libft.a from those .o files.
A good resource to learn about Makefile is www.makefiletutorial.com and https://www.gnu.org/software/make/.
- Rename your local libft directory/repo to "libft".
- Change to the libft's parent directory and clone the libft-unit-test repository:
git clone https://github.com/alelievr/libft-unit-test.git
Your folder structure should now look like this:
.
|- libft/
|- libft-unit-tests/
- Edit libft/Makefile and add the following rule to the bottom:
so:
$(CC) -nostartfiles -fPIC $(CFLAGS) $(SRC)
gcc -nostartfiles -shared -o libft.so $(OBJ)
Change $(CC), $(SRC) and $(OBJ) to the variable names you used for your compiler, your source and object files in your Makefile. You don't need to change $(CFLAGS) even if you haven't defined this variable.
- Change to the libft-unit-tests directory
- Complete the installation by running
make
Your tests should be correctly installed now!
- Go to the libft-unit-tests directory and run
make f
You should now see your test results!
If you want to benchmark your functions against the system library run
make b
