Re: [OMPI devel] make check failing

Simple, because the test that eventually segfaults only runs if ompi is 
configured with threading. Otherwise it is a no-op.

Hi,

We have been having a problem lately with our MTT runs where make

would fail when mpi threads were enabled.

Turns out the problem is that opal_init now calls
opal_base_carto_select, which cannot find any carto modules since we
have not done an install yet. So it returns a failure. This causes
opal_init to abort before initializing the event engine. So when we  
try
to do the threading tests, the event engine is uninitialized and  
fails.


So this is why it fails, but I do not know how best to fix it. Any
suggestions would be appreciated.

[OMPI devel] make check failing

[Tim Prins]

Hi,

We have been having a problem lately with our MTT runs where make check 
would fail when mpi threads were enabled.


Turns out the problem is that opal_init now calls 
opal_base_carto_select, which cannot find any carto modules since we 
have not done an install yet. So it returns a failure. This causes 
opal_init to abort before initializing the event engine. So when we try 
to do the threading tests, the event engine is uninitialized and fails.


So this is why it fails, but I do not know how best to fix it. Any 
suggestions would be appreciated.
