Same Makefile, Different Results

Same Makefile, Different Results
So you run make b and get "b" like you expected. Cool. Then you try dmake -s b thinking it'll do the same thing, and suddenly target 'a' decides to run first and you get "a" followed by "a: no action was taken." Welcome to the wonderful world of build systems where POSIX compliance is more of a suggestion than a rule. Different make implementations parse dependencies differently, and dmake (Sun's make) apparently has its own ideas about how your Makefile should work. Same file, same rules, completely different execution order. It's like having two compilers that interpret the same code differently—which, let's be honest, also happens more than we'd like to admit. The real fun starts when your CI/CD pipeline uses a different make implementation than your local machine. Good times.

When Your Makefile Is Ruined

When Your Makefile Is Ruined
The silent killer of build systems: auto-detected indentation. One developer uses tabs, another uses spaces, and suddenly your Makefile implodes because it requires exact tab characters for rules. The editor helpfully "fixed" your indentation and now your CI pipeline is a burning building behind you while you smile, knowing exactly who to blame. Nothing says "welcome to dependency hell" like watching four months of work collapse because someone's IDE thought it knew better than GNU Make's 1976 tab requirement.
