This is a prerequisite for the code change that uses the TSS rather
than the command line tools.

But pcr_tsspcrread.c uses the binary (tsspcrread).
pcr_tss.c uses TSS, but that's already covered:
ldd src/.libs/evmctl |grep tss
libtss2-rc.so.0 => /usr/lib64/libtss2-rc.so.0 (0x00007fb82514c000)
libtss2-esys.so.0 => /usr/lib64/libtss2-esys.so.0 (0x00007fb824eba000)
libtss2-sys.so.0 => /usr/lib64/libtss2-sys.so.0 (0x00007fb8244ba000)
libtss2-mu.so.0 => /usr/lib64/libtss2-mu.so.0 (0x00007fb824276000)
Thus I thing this patch is invalid. Or do I miss something obvious?
And other thing: could you please rebase your patches for next-testing branch?
It's not applicable for master, next and next-testing.
Kind regards,
Petr

The idea is to eliminate the calls to command line utilities, which
are not as stable as the TSS library. Patch 4/6 does that.
I'm a git newbie. I thought the idea was to do the patches as
small pieces. Thus, this one does the autotools piece. Then
the next one does the C code. Should they be combined?

There are two TSSes. This one's for the IBM TSS. Your traces are
for the ESAPI API (aka Intel TSS).

I'm sorry, I overlooked that.

I'd personally put it into the 4/6 patch (code change is small and it's related
to the code change).

Thanks for explanation.
