compiling bin-i386-efi/snponly.efi

[hildred]

I am trying to compile bin-i386-efi/snponly.efi for booting a early mac mini and I am getting a huge number of errors regarding relocation truncation. I assume this means there are too many components selected. Is this the case? if so what should I disable?

Code:

You should report this on the mailing-list where the developers might be able to help you. If you're trying to compile using Xcode then you might have a slightly broken/old GCC toolchain.

As to the current state of affairs:

When compiling snponly.efi it will fail if you try to create a version that will load any binary that is not efi, including linux bzimages. recent linux kernels can also be efi, or you need a loader.
