| 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 |  |

|---|
| 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.  Andreas Stolcke <stolcke@speech.sri.com> |

| 81 | PROBLEMS | 
|---|
| 82 | -------- | 
|---|
| 83 |  | 
|---|
| 84 | SunOS 4.1.x: | 
|---|
| 85 | The customs/sprite.h header file #includes the <malloc.h> header | 
|---|
| 86 | files; this conflicts with GNU make's configuration so you'll get a | 
|---|
| 87 | compile error if you use GCC (or any other ANSI-capable C compiler). | 
|---|
| 88 |  | 
|---|
| 89 | I commented out the #include in sprite.h:107: | 
|---|
| 90 |  | 
|---|
| 91 | #if defined(sun) || defined(ultrix) || defined(hpux) || defined(sgi) | 
|---|
| 92 | /* #include <malloc.h> */ | 
|---|
| 93 | #else | 
|---|
| 94 |  | 
|---|
| 95 | YMMV. |
