0715802f52 missed that there is a call
to a common/verbs_usnic symbol in the common/verbs component. This
call needs to be compiled out when the common/verbs_usnic component is
not built.

# This component is a workaround to a bug in libibverbs that prints a
|
|
# dire warning that usNIC devices are not supported (of course not --
|
|
# usNIC devices provide functionality through libfabric, not
|
|
# libibverbs). This component was written before a better workaround
|
|
# was created: a "no op" libibverbs plugin for usNIC devices
|
|
# (https://github.com/cisco/libusnic_verbs, and is also available in
|
|
# binary form on cisco.com).
|
|
#
|
|
# Hence, this component no longer builds by default. It's still
|
|
# available if a user specifically asks for it (e.g., if they do not
|
|
# want to install the "no op" libibverbs plugin), but it's not the
|
|
# default. This component also has the side-effect of making
|
|
# libopen-pal.so depend on libibverbs.so, which can be annoying for
|
|
# packagers (which is another reason it isn't built by default any
|
|
# more).
|
|
#
|
|
# This component must be linked statically into libopen-pal because it
|
|
# registers a provider for libibverbs at run time, and there's no
|
|
# libibverbs API to *un*register a plugin. Hence, we can't allow this
|
|
# code to be dlclosed/removed from the process. Hence: it must be
|
|
# compiled statically into libopen-pal.
