-*-indented-text-*- GNU make can utilize the Customs library, distributed with Pmake, to provide builds distributed across multiple hosts. In order to utilize this capability, you must first download and build the Customs library. 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.

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) 1998-2019 Free Software Foundation, Inc.
