I have download xen unstable tree which include your efi patch,and try to build xen.efi ,but there only have xen.gz ,don't have xen.efi .I find the file xen\arch\x86\efi\disable have report some error : ld don't support -m i386pep. my gcc version is 4.6.1.
if modify the i386pep to elf_x86_64 ,the build can continue ,and report other error --subsystem=10 and --image-base=0xffff82c480000000 unrecognized.
do you have any suggestion about that? thank you very much!

the detail is follow.

ld: unrecognized option '--image-base=0xffff82c480000000'

In the xen/arch/x86/efi/disabled

ld: unrecognized emulation mode: i386pep

The i386pep defines what type of executable the binary will be. You do not want an x86_64 ELF, you want an i386 Portable Executable Program (I think that is what PEP stands for). Google should have some details on how build/install an cross compiler for i386pep. > report other error --subsystem=10 and > --image-base=0xffff82c480000000 unrecognized. > do you have any suggestion about that? thank you very much! > > the detail is follow. > ld: unrecognized option '--image-base=0xffff82c480000000' > > In the xen/arch/x86/efi/disabled > ld: unrecognized emulation mode: i386pep > Supported emulations: elf_x86_64 elf32_x86_64 elf_i386 i386linux elf_l1om > > liang. > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Jan Beulich" Subject: Re: Need some help about the build xen.efi Date: Wed, 02 Nov 2011 10:34:14 +0000 Message-ID: <4EB12AB6020000780005E679@nat28.tlf.novell.com> References: <4EAEAC4B.4000004@oracle.com> Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Return-path: In-Reply-To: <4EAEAC4B.4000004@oracle.com> Content-Disposition: inline List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xensource.com Errors-To: xen-devel-bounces@lists.xensource.com To: liang tang Cc: "xen-devel@lists.xensource.com" , Konrad Rzeszutek Wilk List-Id: xen-devel@lists.xenproject.org >>> On 31.10.11 at 15:10, liang tang wrote: > Hi,Jan > I have download xen unstable tree which include your efi patch,and = try=20 > to build xen.efi ,but there only have xen.gz ,don't have xen.efi .I = find=20 > the file xen\arch\x86\efi\disable have report some error : ld don't =20 > support -m i386pep. my gcc version is 4.6.1.

Looks like it is (otherwise you would see some sort of error message). > any idea about that? If you're having real problems, the may be connected to the EFI implementation on your system and/or the EFI version being too old (no minimum version was established so far, but it may well be that some things aren't working as expected in older versions). I take it that native Linux boots okay on that system? Jan
