Re: [Xen-devel] Mini-OS Makefile and Cross Compilation
The command in my previous post should have been:
$ make CROSS_COMPILE=$HOME/opt/i386-elf/bin/i386-elf- TARGET_ARCH=x86_32
not this:
$ make CROSS_COMPILE=$HOME/opt/i386-elf/i386-elf/bin/ TARGET_ARCH=x86_32
This should allow the makefile to find the correct version of objcopy.

Last summer, I cross-compiled a 32-bit minios for 32-bit Xen so that I
could build an application in the Lua scripting language. The
interpreter required a C library, so I used newlib.
On a 32-bit machine, I can still build Mini-OS with a cross compiler
with:
$ make CROSS_COMPILE=$HOME/opt/cross/bin/i386-elf-
The problem seems to be when specifying a different target
architecture. I also can no longer build a minios library to link
with the application, I'm not worried about that now.
By the way, the latest version of newlib, 1.15.0, no longer needs to
be patched for use with Mini-OS.
