tpm2-tss requires libgcrypt20 (at least that's was it's called on Ubuntu).

libgcrypt (which is the 1.x branch) is quite old and had a different API than the 20 series...

Maybe that's the problem...

Subject: [tpm2] does anyone compile tpm2-tss-2.1.0 successful on CentOS7?

I have updated libgpg-error, libgcrypt-devel, etc..
