-*-indented-text-*-GNU Make can utilize the Customs library, distributed with Pmake, toprovide builds distributed across multiple hosts.In order to utilize this capability, you must first download and buildthe Customs library.  It is contained in the Pmake distribution, whichcan be obtained at:  ftp://ftp.icsi.berkeley.edu/pub/ai/stolcke/software/This integration was tested (superficially) with Pmake 2.1.33.BUILDING CUSTOMS----------------First, build pmake and Customs.  You need to build pmake first, becauseCustoms require pmake to build.  Unfortunately, this is not trivial;please see the pmake and Customs documentation for details.  The bestplace to look for instructions is in the pmake-2.1.33/INSTALL file.Note that the 2.1.33 Pmake distribution comes with a set of patches toGNU Make, distributed in the pmake-2.1.33/etc/gnumake/ directory.  Thesepatches are based on GNU Make 3.75 (there are patches for earlierversions of GNU Make, also).  The parts of this patchfile which relatedirectly to Customs support have already been incorporated into thisversion of GNU Make, so you should _NOT_ apply the patch file.However, there are a few non-Customs specific (as far as I could tell)changes here which are not incorporated (for example, the modificationto try expanding -lfoo to libfoo.so).  If you rely on these changesyou'll need to re-apply them by hand.Install the Customs library and header files according to thedocumentation.  You should also install the man pages (contrary tocomments in the documentation, they weren't installed automatically forme; I had to cd to the 'pmake-2.1.33/doc' directory and run 'pmakeinstall' there directly).BUILDING GNU MAKE-----------------Once you've installed Customs, you can build GNU Make to use it.  Whenconfiguring GNU Make, merely use the '--with-customs=DIR' option.Provide the directory containing the 'lib' and 'include/customs'subdirectories as DIR.  For example, if you installed the customslibrary in /usr/local/lib and the headers in /usr/local/include/customs,then you'd pass '--with-customs=/usr/local' as an option to configure.Run make (or use build.sh) normally to build GNU Make as described inthe INSTALL file.See the documentation for Customs for information on starting andconfiguring Customs.INVOKING CUSTOMS-IZED GNU MAKE-----------------------------One thing you should be aware of is that the default build environmentfor Customs requires root permissions.  Practically, this means that GNUmake must be installed setuid root to use Customs.If you don't want to do this, you can build Customs such that rootpermissions are not necessary.  Andreas Stolcke <stolcke@speech.sri.com>writes: > pmake, gnumake or any other customs client program is not required to > be suid root if customs was compiled WITHOUT the USE_RESERVED_PORTS > option in customs/config.h.  Make sure the "customs" service in > /etc/services is defined accordingly (port 8231 instead of 1001). > Not using USE_RESERVED_PORTS means that a user with programming > skills could impersonate another user by writing a fake customs > client that pretends to be someone other than himself.  See the > discussion in etc/SECURITY.PROBLEMS--------SunOS 4.1.x:  The customs/sprite.h header file #includes the <malloc.h> header  files; this conflicts with GNU Make's configuration so you'll get a  compile error if you use GCC (or any other ANSI-capable C compiler).  I commented out the #include in sprite.h:107:    #if defined(sun) || defined(ultrix) || defined(hpux) || defined(sgi)    /* #include <malloc.h> */    #else  YMMV.-------------------------------------------------------------------------------Copyright (C) 1998-2024 Free Software Foundation, Inc.This file is part of GNU Make.GNU Make is free software; you can redistribute it and/or modify it under theterms of the GNU General Public License as published by the Free SoftwareFoundation; either version 3 of the License, or (at your option) any laterversion.GNU Make is distributed in the hope that it will be useful, but WITHOUT ANYWARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FORA PARTICULAR PURPOSE.
