In ompi/contrib/vt/vt/extlib/otf/acinclude.m4, in the macros WITH_DEBUG
and WITH_VERBOSE, dubious constructs such as
are used. These have the following problems:
* Cache variables need to match *_cv_* in order to actually be saved
(where the bit before _cv_ is preferably a package or author prefix,
for namespace cleanliness; see
The next Autoconf version will warn about this.
* There is little need to cache information that the user provided on
the configure command line. If configure is rerun by './config.status
--recheck', it remembers the original configure command line. Only if
the user manually reruns configure (and keeps config.cache) does this
make a difference.
So I suggest you remove those two instances of AC_CACHE_CHECK usage,
or forward this information to the author of oft.
