Hi,
Here is an updated set of patches.
I haven't tested with schroot on amd64, nor to boot a real alpha workstation
- and I'm afraid it won't happen very soon.
I hope it will help nevertheless !
Regards,
JH Chatenet

Description: cross-compilation support with gcc-alpha-linux-gnu
The source package now depends on gcc-alpha-linux-gnu on arch !alpha
.
Three (possibly different) compilers are needed :
1. a native one to compile helpers which run during the build
2. one to generate Alpha code to build aboot-base (and possibly aboot)
3. one to generate $DEB_HOST_ARCH code to build aboot-cross
debian/rules sets variables for each.

Description : fix for a conflict in 'long' type definitions.
_u64 means long on alpha, and long long on amd64 [1].
A mismatch may occur when cross-compiling for alpha on amd64.
.
Include <linux/types.h> early, so ext2fs/ext2_fs.h do not define
these types according to the build architecture (instead of the host
architecture).

Helpers are needed to build the alpha binaries.

Description : build depends on a virtual package when cross-compiling
When cross compiling, build depends on the virtual package
'e2fslibs-dev' (which libext2fs-dev provides) to avoid an
error due to a mismatch between the host and build architectures.

Description : preliminary support to cross build aboot
To build aboot and aboot-base (and the source package) on amd64
(gcc-alpha-linux-gnu and libc6.1-dev-alpha-cross are installed) :
dpkg-buildpackage --host-arch=alpha --build-profiles=cross -uc -us
.
To build aboot-cross for arm64 on amd64 (crossbuild-essential-arm64 is
installed, and gcc-alpha-linux-gnu and libc6.1-dev-alpha-cross as well,
even if they are not really useful in this case) :
dpkg-buildpackage -B --host-arch=arm64 --build-profiles=cross -uc -us
