Also, make sure you make clean before since there are some ifdefery magic to
choose the default TCTI used.

You can force using a specific TCTI with the common options or environment
variables, i.e:

$ tpm2_pcrlist -L sha1:7 -T abrmd

The tools were not linked against libtcti-tabrmd, after reconfiguring, doing a
clean, and rebuilding, it now is working.

Ah, sorry. I misunderstood your issue.

The only thing that I can think of is that your tpm2-tools were not built with
TCTI abrmd support. This may happen if you built tpm2-tools before tpm2-abrmd,
since tpm2-tools' configure script check for the TCTI abrmd header and libs.

Can you please check if configure said: "checking for TCTI_TABRMD... yes" and
if your tools binaries are dynamically linked against the TCTI tabrmd library?

$ ldd $(which tpm2_pcrlist) | grep libtcti-tabrmd
        libtcti-tabrmd.so.0 => /lib64/libtcti-tabrmd.so.0 (0x00007f3adf9a8000)

Actually, I do want to use the physical TPM device.  As a diagnostic step I
built --with-simulatorbin to see what happened.  But, I would like to see
the hardware device work.

Since your distro is Ubuntu, and you want to use the tabrmd resource manager and
the simulator, I would double check your steps with the ones made by the Travis
CI, since it does the same that you want:

https://github.com/01org/tpm2-tools/blob/master/.travis.yml#L51

If you find any divergence between what's done there and the INSTALL file, please
file an issue.

I think the problem is that you are using --tcti=device (and so telling the RM
to access the TPM device directly). But IIUC you want to use the simulator, so
instead need to do:

$ sudo -u tss tpm2-abrmd --tcti=socket

[tpm2] ERROR: Failed to initialize tcti context: 0x1

[Stuart Yoder]

[-- Attachment #1: Type: text/plain, Size: 937 bytes --]

I'm trying to build/test tpm2-tools and am running into an issue.  This is on
an Ubuntu 16.04 machine and I know the tpm is alive and functioning
because the distro tpm2-tools package worked.  That's an older codebase, so I
wanted to build everything from source.

So I've successfully built:  tpm2-tss, tpm2-tools, tpm2-abrmd.

I followed the build/install instructions here:
https://github.com/01org/tpm2-abrmd/issues/92
...which seem to follow what is recommended in INSTALL.md.

I start tpm2-abrmd like this:
sudo -u tss tpm2-abrmd --tcti=device &

..and it runs, but when running a command like
tpm2_pcrlist I get this error:

   ERROR: Failed to initialize tcti context: 0x1

Also, I built abrmb with these options:
--enable-unit --with-simulatorbin=/usr/local/bin/tpm_server

...and ran make check.  The unit tests pass, but the
integration tests fail.

Anything obvious I am missing?

Thanks,
Stuart
