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?
