issue. The ABI file is usually created under misc/rdma_cm, but I believe
that the backport patch moves the rdma_cm directory under infiniband.
(The misc directory doesn’t exist.) The library typically looks under
misc/rdma_cm. (Note that very old versions of the RDMA CM did not create
an ABI file, so it’s possible that you have that version.)</span></font></p>
