Hi there,

here is another test failure I am seeing on Mac OS X 10.7.4 with automake 1.12.2. Specifically, two tap test fail with errors. So when I execute

   make check TESTS="t/suffix8.tap t/suffix10.tap"

then I get this (after removing some fluff):


PASS: t/suffix8.tap 1 - libtoolize
PASS: t/suffix8.tap 2 - aclocal
PASS: t/suffix8.tap 3 - autoconf
PASS: t/suffix8.tap 4 - automake

I think the problem is caused by the "configure" script spitting out these messages:

checking for archiver @FILE support... rm: cannot remove `conftest.dSYM': Is a directory
no
checking for strip... strip
checking for ranlib... ranlib
checking command to parse /usr/bin/nm output from cc object... rm: cannot remove `conftest.dSYM': Is a directory
ok

Note the isolated "ok" on a line of its own; apparently this makes the test think that an unplanned test step occurred.


This in turn is caused by a "bug" in libtool -- or rather, there is a peculiar behavior of the Mac OS X compilers (namely to create conftest.dSYM directories under certain circumstances), and libtool hence needs to replace "rm -f conftest*" by "rm -rf conftest*". This was done some years ago, but apparently was forgotten in three cases.

I already reported this to libtool: <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11895>
But since it directly affects the test suite of automake, I thought it best to report this here, too. Perhaps you would like to workaround it by making the test a bit more strict about how it detects a completed test step?


Cheers,
Max
