I have used the option "--enable-targets=all". If this doesn't work why

What does your "objcopy --help" say?

I think EFI x86-64 is supported.  Why do you think it isn't supported?

I quote the README from gnu-efi:

.......... quote begin ............

- A version of "objcopy" that supports EFI applications.  To
        check if your version includes EFI support, issue the

          objcopy --help

        Verify that the line "supported targets" contains the string
        "efi-app-ia32" and "efi-app-x86_64" and that the "-j" option
        accepts wildcards.

............ quote end ............

That's why I assume that it's not supporting it.


efi-app-x86_64 is translated to pei-x86_64.

I'm going to fix the misleading gnu-efi readme. So I have to replace not only the 64 bit variant, but efi-app-ia32, too, despite the fact that I don't want to use the 32 bit variant myself. For that goal I've read that bugzilla file again and again thoroughly, but it escapes me to what efi-app-ia32 is translated to. I can't dinf a "pei-ia32". Could you, please, tell me?

Kind regards

Peter Wiehe
