Jam - make(1) redux /+\ +\ Copyright 1993-2002 Christopher Seiwald and Perforce Software, Inc. \+/ This is Release 2.5 of Jam, a make-like program. License is hereby granted to use this software and distribute it freely, as long as this copyright notice is retained and modifications are clearly marked. ALL WARRANTIES ARE HEREBY DISCLAIMED. FEATURES -> Jam is a make(1) replacement that makes building simple things simple and building complicated things manageable. -> Jam's language is expressive, making Jamfiles (c.f. Makefiles) compact. Here's a sample: Main smail : main.c map.c resolve.c deliver.c misc.c parser.y alias.c pw.c headers.c scanner.l getpath.c str.c ; This builds "smail" from a dozen source files. Jam handles header file dependencies automatically and on-the-fly. -> Jam is very portable: it runs on UNIX, VMS, Mac, and NT. Most Jamfiles themselves are portable, like the sample above. -> Jam is unintrusive: it is small, it has negligible CPU overhead, and it doesn't create any of its own funny files (c.f. Odin, nmake, SunOS make). -> Jam can build large projects spread across many directories in one pass, without recursing, tracking the relationships among all files. Jam can do this with multiple, concurrent processes. -> Jam isn't under the blinkin GNU copyright, so you can incorporate it into commercial products. INFORMATION GUIDE Jam.html jam and language reference. Jambase.html Reference for the Jambase boilerplate file. Jamfile.html Easy reading on creating a Jamfile and using jam. RELNOTES Release 2.3 release notes. Porting Notes on porting jam to wildcat platforms. README This file. Includes installation instructions. jam.c Contains the jam command's main() as well as an introduction to the code, for serious hackers. INSTALLING The Makefile (UNIX, NT), build.com (VMS), Build.mpw (Mac MPW) are for bootstrapping. Once jam is built, it can rebuild itself. UNIX Build jam with make(1) on: Platform $(OS) ------------------------- AIX AIX * BSD/386 1.0 BSDI COHERENT/386 COHERENT DGUX 5.4 DGUX FreeBSD FREEBSD HPUX 9.0 HPUX IRIX 5.0 IRIX Linux LINUX NEXTSTEP 3.2 NEXT OSF/1 OSF PTX V2.1.0 PTX Solaris 2 SOLARIS * SunOS4.1 SUNOS Ultrix 4.2 ULTRIX BeOS BEOS * * requires editing Makefile Windows Build jam with nmake on: Platform $(OS) ------------------------- NT NT * OS/2 OS2 * The NT MAXLINE (command line length) is still set in jam.h to 996, which was apparently the NT 3.5 limit. On 4.0, the limit is somewhere around 10K. For now, you can increase MAXLINE in jam.h so that a jam running on 4.0 will use the full command line length, but that jam.exe will fail miserably on the older OS. On NT, a variable must be set before invoking jam to tell it where the C compiler lives. The name of this variable depends on which compiler you are using: BCCROOT: The Borland C compiler MSVCDIR: The Microsoft Compiler 6.0 (for NT) MSVCNT: The Microsoft Compiler 5.0 (for NT) MSVC: The Microsoft Compiler 1.5 (for Windows) Only MSVCNT and MSVCDIR have really been tested and are known to work. Macintosh Build jam with Build.mpw on: Platform $(OS) ------------------------- Macintosh MAC You'll need to edit Build.mpw to set CW. VMS Build jam with @build.com on: Platform $(OS) ------------------------- VMS 5.4 VMS OPENVMS OPENVMS Comments to the author!

Jam 2.3 + Perforce's internal changes.
This change is a drop of the Perforce internal Jam changes
since the 2.3 public release. The individual changes
represented herein are preserved in the
The intent of this drop is to provide a base, from which other
contributors' Jam branches may be integrated into. It is not
intended to become a packaged release in this state. We will
be integrating changes from other users prior to creating the
next packaged release.
Please refer to the src/RELNOTES file for an overview of the
changes present in this integration.

Just about every source file was touched when jam got ANSI-fied.
