make, or omake, is a portable version of the OpenBSD make program. It is currently synced with OpenBSD 6.9 -current as of July 22, 2021.

This version of make is suitable for ensuring standard Make compliance, for older Unix machines that do not have a free Make or have a very old Make, or for users that do not need the bells and whistles of bmake or GNU Make.

make has no dependencies other than libc. It is known to build and run on all *BSD flavors, Linux, Mac OS X, Cygwin, AIX, and Solaris. It is very likely to run on other Unix flavors; please let me know if you are using this on a Unix not listed here so that I may add it to the list.

To build, run:

$ ./configure
$ make
# make install

The following compilers are known to build make:

• Clang
• GCC
• PCC
• TinyCC
• CParser
• CompCert
• lacc

It is likely that any C99 compiler will work.

Tested on Linux and Mac OS X using TravisCI. *BSD, Cygwin, AIX, and Solaris testing done manually. AIX 5.1L and Solaris 8 are used to help ensure backwards compatibility.

All C files other than portable.c are 2- and 3-clause BSD licensed. portable.c has a combination of Public Domain, ISC, and 3-clause BSD licensed code.
