cffi.CDefError: only supports one of the following syntax

[DylanFromEdwards]

Hi,

I'm attempting to install tpm2-pytss into a venv and I get a metadata error preventing me from doing so.

I suspect the offending line is the (-1) ???

  cffi.CDefError: only supports one of the following syntax:
    #define TSS2_TCTI_TIMEOUT_BLOCK ...     (literally dot-dot-dot)
    #define TSS2_TCTI_TIMEOUT_BLOCK NUMBER  (with NUMBER an integer constant, decimal/hex/octal)
  got:
    #define TSS2_TCTI_TIMEOUT_BLOCK (-1)

The full output is included below. Would someone be able to help me solve this issue?

Kind regards, Dylan

Try installing tpm2-pytss with python3 -m pip install git+https://github.com/tpm2-software/tpm2-pytss.git I think it's already fixed in the repo, but not in a release yet

Thank you. That was quick. Works from the main.

An FYI for anyone else facing this I had to open a root shell with: su -

and do the install.

[DylanFromEdwards]

Thanks - I'll close this issue now.
