It is contained in the Pmake distribution, which +can 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, because +Customs require pmake to build. Unfortunately, this is not trivial; +please see the pmake and Customs documentation for details. The best +place 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 to +GNU make, distributed in the pmake-2.1.33/etc/gnumake/ directory. These +patches are based on GNU make 3.75 (there are patches for earlier +versions of GNU make, also). The parts of this patchfile which relate +directly to Customs support have already been incorporated into this +version 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 modification +to try expanding -lfoo to libfoo.so). If you rely on these changes +you'll need to re-apply them by hand. + +Install the Customs library and header files according to the +documentation. You should also install the man pages (contrary to +comments in the documentation, they weren't installed automatically for +me; I had to cd to the 'pmake-2.1.33/doc' directory and run 'pmake +install' there directly). + + +BUILDING GNU MAKE +----------------- + +Once you've installed Customs, you can build GNU make to use it. When +configuring 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 customs +library 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 in +the INSTALL file. + +See the documentation for Customs for information on starting and +configuring Customs. + + +INVOKING CUSTOMS-IZED GNU MAKE +----------------------------- + +One thing you should be aware of is that the default build environment +for Customs requires root permissions. Practically, this means that GNU +make must be installed setuid root to use Customs. + +If you don't want to do this, you can build Customs such that root +permissions are not necessary. Andreas Stolcke +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 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 */ + #else + + YMMV. + + +------------------------------------------------------------------------------- +Copyright (C) 1998-2016 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 the +terms of the GNU General Public License as published by the Free Software +Foundation; either version 3 of the License, or (at your option) any later +version. + +GNU Make is distributed in the hope that it will be useful, but WITHOUT ANY +WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR +A PARTICULAR PURPOSE.
