[Bug scrub] @smijolovic Could you please try latest SPDK as well to confirm ?
We are in process of establishing separate Jenkins job to verify CentOS8 and will be able to check that particular setup. So far we've not encountered this issue. @mikeBashStuff please update with the status when the job is up and running.

Couple of things to note:

/configure --enable-debug --without-isal --with-iscsi-initiator --with-rdma --disable-tests --with-crypto

This particular build would require nasm package in version >= 2.14 which centos8 doesn't provide in its repos (epel, elrepo repos don't provide it either) so I am guessing it's been manually installed on the system through some 3rd-party rpm (or from source maybe). Otherwise, ./configure would simply fail. This is something that our tests would not cover.

That said, I've run the build against latest master (v20.07-rc1-541-g057c92e3d) and v20.07 (1a527e5) on our Centos8 testing image, covering this particular setup and the entire spectrum of the autobuild tests - everything worked just fine.
Also, this fatal error: intel-ipsec-mb.h: No such file or directory is quite peculiar since this header file should be present directly under intel-ipsec-mb submodule. So with that in mind, I would suggest to get a fresh clone of the SPDK repo with all submodules properly initialized and then try to compile once more.

Upgraded to nasm 2.15.05 and still see the same issue:

Make command line links to the intel-ipsec-mb directory...which is where the header file is....but still errors out.

@smijolovic Have you tried to nuke the repo, clone it fresh, update submodules, and then try to compile? Asking since I simply cannot reproduce it on my own setup (testing it against latest master and directly on top of v20.07 ref).

[Bug Scrub] I'm going to close this issue, you can reopen it if the issue still exists.

sudo -E dnf install intel-ipsec-mb.x86_64 intel-ipsec-mb-devel.x86_64 should address it
