1 -*-indented-text-*- 2 3 GNU make can utilize the Customs library, distributed with Pmake, to 4 provide builds distributed across multiple hosts. 5 6 In order to utilize this capability, you must first download and build 7 the Customs library. It is contained in the Pmake distribution, which 8 can be obtained at: 9 10 ftp://ftp.icsi.berkeley.edu/pub/ai/stolcke/software/ 11 12 This integration was tested (superficially) with Pmake 2.1.33. 13 14 15 BUILDING CUSTOMS 16 ---------------- 17 18 First, build pmake and Customs. You need to build pmake first, because 19 Customs require pmake to build. Unfortunately, this is not trivial; 20 please see the pmake and Customs documentation for details. The best 21 place to look for instructions is in the pmake-2.1.33/INSTALL file. 22 23 Note that the 2.1.33 Pmake distribution comes with a set of patches to 24 GNU make, distributed in the pmake-2.1.33/etc/gnumake/ directory. These 25 patches are based on GNU make 3.75 (there are patches for earlier 26 versions of GNU make, also). The parts of this patchfile which relate 27 directly to Customs support have already been incorporated into this 28 version of GNU make, so you should _NOT_ apply the patch file. 29 30 However, there are a few non-Customs specific (as far as I could tell) 31 changes here which are not incorporated (for example, the modification 32 to try expanding -lfoo to libfoo.so). If you rely on these changes 33 you'll need to re-apply them by hand. 34 35 Install the Customs library and header files according to the 36 documentation. You should also install the man pages (contrary to 37 comments in the documentation, they weren't installed automatically for 38 me; I had to cd to the ``pmake-2.1.33/doc'' directory and run ``pmake 39 install'' there directly). 40 41 42 BUILDING GNU MAKE 43 ----------------- 44 45 Once you've installed Customs, you can build GNU make to use it. When 46 configuring GNU make, merely use the ``--with-customs=DIR'' option. 47 Provide the directory containing the ``lib'' and ``include/customs'' 48 subdirectories as DIR. For example, if you installed the customs 49 library in /usr/local/lib and the headers in /usr/local/include/customs, 50 then you'd pass ``--with-customs=/usr/local'' as an option to configure. 51 52 Run make (or use build.sh) normally to build GNU make as described in 53 the INSTALL file. 54 55 See the documentation for Customs for information on starting and 56 configuring Customs. 57 58 59 INVOKING CUSTOMS-IZED GNU MAKE 60 ----------------------------- 61 62 One thing you should be aware of is that the default build environment 63 for Customs requires root permissions. Practically, this means that GNU 64 make must be installed setuid root to use Customs. 65 66 If you don't want to do this, you can build Customs such that root 67 permissions are not necessary.
