Hi,
thanks for the notes and the patch.
Committed revision 33649.
There are also pending updates for booth gnu-efi and elilo, but as
they did neither not yet just build on our continuous integration test
server they are not yet in trunk. I try to take a look on the updates
soon, likewise.
Have fun,
René

Hi,
I had to jump through some strange hoops in order to get elilo built
on an x86 embedded build.
This is what got it to build:
1. there is a dependency, elilo needs gnu-efi, this should be added
to the T2 package documentation on the website. and also to the
internal dependencies.
2. gnu-efi does not build under ia32/x86 arch in the current svn
trunk. there is a linker error:

--- BUILD ERROR ---
Found a fix for this on the RedHat website, it is described here:
https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=492183
A corrected lds file for ia32 was posted here:
https://bugzilla.redhat.com/attachment.cgi?id=337523
I Made a patch for this which is attached.
It now links OK.
