Subject: [OMPI devel] need help to add a module
From: bin wang (bighead521_at_[hidden])

hello,

I'm trying to add a module into open-mpi MCA framework.
I hope the module could be conditionally compiled and linked.
It should be disabled by default and enabled by certain flags at configure
step.

When I make a dynamic module, everything is working fine.
The problem is that when I make a static compilation/link,
the compiler would complain the component variable is not defined.

In my build log, I found something as following,
 1414 --- MCA component btl:mx (m4 configuration macro)
1415 checking for MCA component btl:mx compile mode... static
1416 checking --with-mx value... simple ok (unspecified)
1417 checking --with-mx-libdir value... simple ok (unspecified)
1418 checking myriexpress.h usability... no
1419 checking myriexpress.h presence... no
1420 checking for myriexpress.h... no
1421 checking if MCA component btl:mx can compile... no

Correspondingly the ompi/mca/btl/base/static-components.h had no
declaration of extern mca_btl_mx_component variable.

I think this is the behavior I expect for my module. I checked the
Makefile.am files
but found nothing special.

I'm not familiar with those autotools, can anyone give me some detailed
guidance on what I should do?

Thanks in advance.
