Utmake Instant

For most developers, make is the standard. cmake is the modern overlord. But utmake ? That sounds like a typo. It’s not.

So the next time you type cmake .. && make without a second thought, spare a moment for utmake . It walked so that cross-platform builds could run. Have you ever encountered utmake in the wild? Or do you have your own “legacy build tool that won’t die” story? Share it in the comments below.

If you’re maintaining a system that uses utmake , learning it is a career superpower. You’ll be one of a few hundred engineers worldwide who can debug a build failure from the Clinton administration without breaking a sweat. And those contracts pay extremely well. utmake

In short: utmake was a . The Syntax (Don’t Be Afraid) A typical utmake control file looks alien if you’re used to modern CMake:

TARGET = firmware.elf SOURCES = main.c utils.c INCLUDES = +../inc +./drivers DEFINES = -DDEBUG=1 -DVXWORKS if ($(ARCH) == "ppc603") CC = ccppc CFLAGS = -mcpu=603 -O2 endif For most developers, make is the standard

Wait, utmake ?

RULE generate_romfs : cmd = ./mkromfs $(OUTDIR)/romfs.bin : deps = romfs/* That sounds like a typo

utmake solved this by shipping its own with a fixed set of rules. It didn’t rely on your system’s make . It parsed its own configuration files (often .ut or .utmake ) and generated platform-specific build scripts as a final step.
