|
||||
This directory contains a port of the BSD make tool (from NetBSD).
|
||||
Since 1993 I have run it on AIX, BSDi, Darwin, FreeBSD, HP-UX, IRIX,
|
||||
Linux, Minix, OSF, Solaris, SunOS and even UTS.
|
||||
Others have run it on many more systems.
|
||||
|
||||
Version 3 was re-worked from scratch to better facilitate
|
||||
importing newer make(1) versions from NetBSD. The original code base
|
||||
was NetBSD-1.0, so version 3 was built by doing a fresh import of the
|
||||
NetBSD-1.0 usr.bin/make, adding the autoconf and other portability
|
||||
patches to sync it with bmake v2, and then NetBSD's make
|
||||
of Feb 20, 2000 was imported and conflicts dealt with.
|
||||
NetBSD's make was again imported on June 6 and December 15, 2000.
|
||||
Currently each release is tested on NetBSD, FreeBSD, Solaris and Linux.
|
||||
|
||||
In 2003 bmake switched to a date based version (first was 20030714)
|
||||
Since 2003 bmake switched to a date based version (first was 20030714)
|
||||
which generally represents the date it was last merged with NetBSD's
|
||||
make. Since then, NetBSD's make is imported within a week of any
|
||||
interesting changes, so that bmake tracks it very closely.

The preferred way to bootstrap bmake is:
|
||||
The preferred way to bootstrap bmake is::
|
||||
|
||||
./bmake/boot-strap
|
||||
./bmake/boot-strap
|
||||
|
||||
there are a number of args - most of which get passed to configure,
|
||||
eg.
|
||||
::
|
||||
|
||||
./bmake/boot-strap --prefix=/opt
|
||||
./bmake/boot-strap --prefix=/opt
|
||||
|
||||
see the boot-strap script for details.
|
||||
|
||||
For folk that hate to read anything, since 20121212 you can also use
|
||||
the GNU standard process of::
|
||||
|
||||
./configure; make; make install
|
||||
|
||||
To make much use of bmake you will need the bsd.*.mk macros or my
|
||||
portable *.mk macros. See
|
||||
portable *.mk macros which are included with bmake since 20121212
|
||||
and separately available from
|
||||
http://www.crufty.net/ftp/pub/sjg/mk.tar.gz
|
||||
which will be links to the latest versions.
|
||||
|
||||
On a non-BSD system, you would want to unpack mk[-YYYYmmdd].tar.gz in
|
||||
the same directory as bmake (so ./mk and ./bmake exist), and
|
||||
./bmake/boot-strap will do the rest.
|
||||
Porting
|
||||
=======
|
||||
|
||||
If you want to do it all by hand then read boot-strap first to get the
|
||||
idea.
|
||||
If you encounter a system that bmake does not build or work on *out of
|
||||
the box*, I welcome patches.
|
||||
If you can provide access to a suitable machine - even better.
|
||||
|
||||
Even if you have an earlier version of bmake installed, use boot-strap
|
||||
to ensure that all goes well.
