Hi,

I was trying to build the Linux UEFI Validation (LUV) image for 32 bit systems. The LUV image incorporates the CHIPSEC test suite as well.

I get the following warnings and errors during build time:

I wanted to know if the CHIPSEC test suite builds and runs on 32 bit platforms? (in which case there is a problem with the CHIPSEC recipe in LUV).

Else, any pointers as to why I see these warnings and errors?

Any help would be appreciated!!

Thanks,

Megha
