Hmmm…no, nothing has changed with regard to declspec that I know
about. I’ll ask the obvious things to check:
* does that component have the proper include to find this function?
Could be that it used to be found thru some chain, but the chain is
now broken and it needs to be directly included
header is included, I double checked.
* is that function in the base code, or down in a component? If the
latter, then that’s a problem, but I’m assuming you didn’t make that
mistake.
I am not sure what you mean. The function is in a component, but I am
not aware that it is illegal to call a function of a component from
another component.
Of course that is illegal - you can only access a function via the
framework interface, not directly. You have no way of knowing that the
other component has been loaded. Doing it directly violates the
abstraction rules.
well, ok. I know that the other componen has been loaded because that
component triggered the initialization of these sub-frameworks.
I can move that functionality to the base, however, none of the 20+
functions are required for the other components of the io framework
(i.e. ROMIO). So I would basically add functionality required for one
component only into the base.
Nevertheless, I think the original question is still valid. We did not
see this problem before, but it is now showing on all of our platforms,
and I am still wandering that is the case. I *know* that the ompio
component is loaded, and I still get the error message about the missing
symbol from the ompio component. I do not understand why that happens.

Has something changed recently on the trunk/master regarding
OMPI_DECLSPEC? The reason I ask is because we get now errors about
unresolved symbols, e.g.
symbol lookup error:
/home/gabriel/OpenMPI/lib64/openmpi/mca_fcoll_dynamic.so: undefined
symbol: ompi_io_ompio_decode_datatype
and that problem was not there roughly two weeks back the last time
I tested. I did verify that the the function listed there has an
OMPI_DECLSPEC before its definition.
