I have finally replicated an issue (where stats.exp mysteriously failed
on his machine but passes on mine) Rob Savoye had mentioned in private
emails a few times and it has an impressively bizarre actual trigger:
the inner runtest(1) invocations from testsuite/runtest.main/stats.exp
fail to start unless the DejaGnu sources were checked out into a
directory literally named 'dejagnu' (all lowercase, without the
quotes). The inner runtest(1) invocations for the options.exp tests are
not affected because they do not actually run any tests and options.exp
matches the output it checks before runtest(1) prepares to run tests.
The problem is that the inner testsuite used for stats.exp is very
minimal and this causes DejaGnu to search "libdir" (which is set
incorrectly in runtest.exp) for a default configuration in
runtest.exp:load_tool_target_config. The runtest.exp file is located in
the correct libdir, whether in a source checkout or installed, but the
code in runtest.exp currently expects runtext.exp to be
LPREFIX/SOMETHING/runtest.exp and sets libdir to LPREFIX/dejagnu. If
the sources are checked out in a 'dejagnu' directory, this happens to
work. If DejaGnu is installed, this happens to work (runtest.exp is
placed in PREFIX/share/dejagnu by default). If the sources are in any
other directory, this does not work.
Report filed to get a bug number to go with the fix. Thanks to Rob
Savoye for mentioning the test failures.
