Failed building wheel for blspy on i686

See original GitHub issue

Hi all,

I am using Debian i686 (it is an old laptop). When trying to compile chia-blockchain from source, following the guide on these pages, I get this error

: error: unknown type name ‘__uint128_t’
     113 | typedef __uint128_t;
 ERROR: Failed building wheel for blspy

Below the full log of the error

  ERROR: Failed building wheel for blspy

The same happens for other components, e.g., chiapos, chiavdf, …

How could I solve this issue?

Thank you.
