I'm guessing something changed elsewhere in the toolchain on RHEL7/SLES12(beta) that is causing this problem. Bert: how is the "hooks" directory normally created? Do you have some specific .m4 that creates it? Or is it a side-effect of something in configure?it is a side affect of the depfiles command called by configure. By coincident, this command is also the reason why we needed to made this change in the first place to support the subdir-objects option of automake. The depfiles command creates the .deps directory using the dirname of the source file if the subdir-objecs option is active. But if the source file contains make file variable references it can't resolve these (remember that it is called by configure) and creates directories like '$(VTUNIFY_ROOT)/hooks/.deps', literally. Now we rely that this depfiles command creates for us the hooks directory. I must admit that this is not bullet proof, and it may actually be removed in the future completely by automake/autoconf [1]. So it is best to handle the creation of this directory inside the VT Makefile altogether. The fix is simple though. Now there is still a problem: Matthias Jurenz is on vacation until August 5th. and I'm completely unfamiliar with the procedure how the VT code is updated in the ompi trunk. For what I see it should go like this: 1. Commit into vendor/vampirtrace/current 2. Merge into trunk/ompi/contrib/vt/vt 3. Create a CMR for 1.8 with reviewer who? (Andreas is on vacation too ;-) Bert [1] http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13928 Read the reply from Stefann: - from Automake 2.0 onward, only enable the automatic dependency tracking if GNU make is used; we can thus assume the presence of the "-include" directive (which ignore non-existing files, rather than punting), and its use will allow us to get rid of the configure time machinery for the initial creation of .deps directories (this has already been done in Automake-NG, and has worked beautifully so far). _______________________________________________ devel mailing list de...@open-mpi.org Subscription: http://www.open-mpi.org/mailman/listinfo.cgi/devel Link to this post: http://www.open-mpi.org/community/lists/devel/2014/07/15252.php
