cross-compiling grub-1.98 i686 to x86_64: gentrigtables

[Eric Herman]

Hello address@hidden helpers,

I'm cross compiling from an i686 linux host for an x86_64 linux target.

It seems that make builds "gentrigtables" (which is an ELF 64-bit LSB 
executable, naturally) then attempts to execute "./gentrigtables > 
trigtables.c"

$ make && echo YAY || echo "DARN $?"
./gentrigtables > trigtables.c
./gentrigtables: 1: ELF

: not found
./gentrigtables: 2: : not found
./gentrigtables: 3: 
: not found
./gentrigtables: 6: 8H: not found
./gentrigtables: 7: H: not found
./gentrigtables: 9: Syntax error: "(" unexpected
make: *** [trigtables.c] Error 2
make: *** Deleting file `trigtables.c'
DARN 2
$ file ./gentrigtables
./gentrigtables: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), 
dynamically linked (uses shared libs), for GNU/Linux 2.6.30, not stripped


Since my i686 host system can only execute ELF 32 binaries, it is no 
surprise that the ELF 64 gentrigtables fails.


In the ChangeLog from 2010-02-06 by Robert Millan I see:
 * gentrigtables.c: New file.  C rewrite of gentrigtables.py

Of course removing dependencies is often a very desirable thing.
However building and executing a binary only works with native builds.
Surely there is a way to work around this.

Looking for "cross-compile" in the ChangeLog I see that on 2009-09-11 
Colin Watson wrote:
        * configure.ac: Don't look for help2man when cross-compiling.
Which is a long time ago.

However, shortly after the 2010-02-06 entry, I see that on 2010-02-13 
that Vladimir Serbinenko wrote:
        Properly create cross-endian images.
Perhaps that suggests he was successfully doing some cross-compiling.

The FAQ is very short, but it points to the wiki: http://grub.enbug.org/
Unfortunately, the wiki is down.


Anyone recently cross-compiled Grub?
Any advice for me?

Cheers,
 -Eric
