MKDEP(1)

💅 mkdep — construct Makefile dependency list ✨

okay bestie, so this is mkdep, and she lives in section 1 of the General Commands Manual. she's a little build-system fairy and honestly? she eats. 🧚

---

🌸 SYNOPSIS 🌸

mkdep [-ap] [-f file] [flags] file [...]

---

🦋 DESCRIPTION 🦋

so here's the vibe: mkdep takes a bunch of flags meant for the C compiler plus a list of C source files, and it constructs a whole set of include file dependencies — and then it writes all of that into the file .depend. periodt. 💖

an example of how you'd use her in a Makefile might look like this:

CFLAGS= -O -I../include
SRCS= file1.c file2.c

depend:
        mkdep ${CFLAGS} ${SRCS}

where the macro SRCS is the list of C source files, and the macro CFLAGS is the list of flags for the C compiler. iykyk. 😌

the options are as follows:

• -a — append to the output file, so that you can run multiple mkdep's from a single Makefile. so many mkdeps, so little time, we love a group project. 🫶
• -f file — write the include file dependencies to file, instead of the default .depend. she's flexible like that. 💅
• -p — cause mkdep to produce dependencies of the form:

program: program.c

so that subsequent makes will produce program directly from its C module rather than using an intermediate .o module. this is useful for programs whose source is contained in a single module. one file, one moment, main character energy. 👑

📜 HISTORY 📜

the mkdep command appeared in 4.3BSD-Tahoe. she's vintage, she's iconic, she's been serving since day one. ⭐

and that's the whole page, bestie!! this was brought to you by the 4.2 Berkeley Distribution, dated June 6, 1993 — yeah she's an elder but she's still slaying, no cap 💀✨🦋
