A lightweight image of bmakelib and GNU Make 4.4
There are two main variants of the image for slightly different usecases:
- openSUSE Tumbleweed
- Ubuntu 22.04 (LTS)
＄ ls
main.c Makefile
＄ cat Makefile
include bmakelib/bmakelib.mk

.PHONY : build

$(binary) : bmakelib.default-if-blank( CC,gcc )
$(binary) : main.c | build/

.PHONY : run

.PHONY : clean
clean :

＄ cat main.c
#include <stdio.h>
int main(void) {
printf("Hello, world\n");
return 0;
}
＄ docker run --rm --volume .:/project bdockerimg/bmakelib run

Here's a real world example of the image being used: bjforth CircleCI configuration
The minimalist Make standard library you'd always wished for!
bmakelib is essentially a collection of useful targets, recipes and variables you can use to augment your Makefiles.
The aim is not to simplify writing Makefiles but rather help you write cleaner and easier to read and maintain Makefiles.
