The test suite was originally written by Steve McGee and Chris Arthur. It is covered by the GNU General Public License (Version 2), described in the file COPYING. It has been maintained as part of GNU make proper since GNU make 3.78. This entire test suite, including all test files, are copyright and distributed under the following terms: ----------------------------------------------------------------------------- Copyright (C) 1992-2024 Free Software Foundation, Inc. This file is part of GNU Make.

See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see <http://www.gnu.org/licenses/>. ----------------------------------------------------------------------------- The test suite requires Perl. These days, you should have at least Perl 5.6. Newer versions may be required: I don't test regularly with older versions than what is installed by default on my development systems. The test suite assumes that the first "diff" it finds on your PATH 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 option (i.e., "perl run_make_tests -make /usr/local/src/make-latest/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 tests :)) 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). This shouldn't happen very often anymore: I've done a lot of work on the tests to reduce the impacts of this situation. 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. Open Issues ----------- The test suite has a number of problems which should be addressed. One VERY serious one is that there is no real documentation. You just have to see the existing tests. Use the newer tests: many of the tests haven't been updated to use the latest/greatest test methods. See the ChangeLogs for pointers. The second serious problem is that it's not relocatable: when you build out of the source tree it creates symlinks, which doesn't work on every system and is just bogus to boot. The third serious problem is that it's not parallelizable: it scribbles all over its installation directory and so can only test one make at a time. The fourth serious problem is that since the tests scribble all over the same directory (a) they can interfere with each other and (b) we cannot preserve the full environment for every test, if it involves creating temporary files etc. as they must be deleted before the next test. To solve these the suite should create a separate directory for EVERY test, local to the build directory, and all temporary files should exist in that directory. The directory can be preserved on error, or removed if the test succeeds (unless --keep is given). Bugs ---- Any complaints/suggestions/bugs/etc. for the test suite itself should be handled the same way as normal GNU make bugs/problems (see the README for GNU make). Paul D. Smith Chris Arthur
