See the file NEWS for some of the changes since the last +release. + +This release is made by psmith@gnu.org to correspond to GNU make 3.78. +It won't work correctly for versions before that. In addition to some +infrastructure changes I've added a number of new tests. + +Rob Tulloh has contributed changes to get the suite running on NT. + +Eli Zaretski and Esa A E Peuha <peuha@cc.helsinki.fi> have contributed +changes to the get the suite running on DJGPP/DOS. + +This package has a number of problems which preclude me from +distributing it with make as a default "make check" test suite. The +most serious of these is that it's not parallelizable: it scribbles all +over its installation directory and so can only test one make at a +time. I simply don't have time to do more with this than I am so far; +I'm very actively interested in finding someone willing to overhaul the +test suite infrastructure. If you're interested, contact me (see below)! + +The test suite thus far has been written by Steve McGee, Chris Arthur, +and Paul D. Smith. It is covered by the GNU General Public License +(Version 2), described in the file COPYING. + +The test suite requires Perl and is known to work with Perl 4.036 and +Perl 5.004 (available from ftp.gnu.org, and portable to many machines). +Earlier or later versions may work; I don't know. It assumes that the +first "diff" it finds is GNU diff, but that only matters if a test +fails. + +To run the test suite on a UNIX system, use "perl ./run_make_tests" +(or just "./run_make_tests" if you have a perl on your PATH). + +To run the test suite on Windows NT or DOS systems, use +"perl.exe ./run_make-tests.pl". + +By default, the test engine picks up the first executable called "make" +that it finds in your path. You may use the -make_path option (ie, +"perl run_make_tests -make_path /usr/local/src/make-3.78/make") if +you want to run a particular copy. This now works correctly with +relative paths and when make is called something other than "make" (like +"gmake"). + +Tests cannot end with a "~" character, as the test suite will ignore any +that do (I was tired of having it run my Emacs backup files as test :) + +If you want to run the tests in parallel, you should use the mkshadow +script included here to create temporary "copies" (via symbolic links) +of the test suite, one for each parallel job. This is a pain and one +day maybe the test suite will be rewritten so it's no longer +necessary--volunteers welcome! + +Also, sometimes the tests may behave strangely on networked +filesystems. You can use mkshadow to create a copy of the test suite in +/tmp or similar, and try again. If the error disappears, it's an issue +with your network or file server, not GNU make (I believe). + +The options/dash-l test will not really test anything if the copy of +make you are using can't obtain the system load. Some systems require +make to be setgid sys or kmem for this; if you don't want to install +make just to test it, make it setgid to kmem or whatever group /dev/kmem +is (ie, "chgrp kmem make;chmod g+s make" as root). In any case, the +options/dash-l test should no longer *fail* because make can't read +/dev/kmem. + +A directory named "work" will be created when the tests are run which +will contain any makefiles and "diff" files of tests that fail so that +you may look at them afterward to see the output of make and the +expected result. + +There is a -help option which will give you more information about the +other possible options for the test suite. + +Any complaints/suggestions/bugs/etc. for the test suite itself (as +opposed to problems in make that the suite finds) should be sent to +psmith@gnu.org. Enjoy! + Paul D. Smith + Chris Arthur |
