CHIPSEC error when building LUV image

CHIPSEC error when building LUV image

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

I don't know the cause of your problems, but the CHIPSEC PDF says
Windows x86/x64, and says that on Linux, Debian is the only one
explicitly listed with 32-bit, Fedora and Ubuntu say 64-bit, LUV entry
does not specify.

If possible to build LUV with LLVM clang, you might try that, it gives
much better warnings than GCC.

I've only built CHIPSEC on Linux, and only for 64-bit targets. And I'm
afraid I can't help building a local LUV at the moment, sorry.

You might also want to ask on the LUV list about this build error. This
might be a LUV-centric issue. The LUV team ported CHIPSEC to their
system. The CHIPSEC team -- AFAIK -- has/have been using an alternative
Linux live-boot solution until recently, so the LUV team may be better
to answer a LUV-centric build question than the CHIPSEC team.

I wonder:
Does a 32- and 64-bit LUV behave differently, w/r/t firmware tests, on
different architectures?
Does CHIPSEC behave differently on when built 32- or 64-bit -- on Linux
or Windows or UEFI?
Perhaps we need LUV64-live and LUV32-live to solve??
Gettting more confused as I type, so I'll stop typing. :-)
