bug#50858: Installing git-annex for aarch64 fails on ghc build

Hi Guix!

I'm trying to install git-annex for aarch64, but it fails on the following
line:

\ 'configure-bin' phasebuilder for
`/gnu/store/b6j0zdnbpdhx81npbk25m4nls5y1h3f5-ghc-7.10.2.drv' failed with
exit code 1

I have attached the log for the failed ghc build.  The first error there
seems to be:

/tmp/guix-build-ghc-7.10.2.drv-0/ghc-7.10.2/ghc-bin/ghc-7.8.4/utils/ghc-pwd/dist-install/build/tmp/ghc-pwd:
cannot execute binary file: Exec format error

Seeing as this works fine for x86, I'm guessing that a ghc-pwd is being
used that was compiled for x86, maybe an error in setting up cross
compiling?

Thanks,
Zacchae

Are you doing --target=aarch64-linux-gnu or --system=aarch64-linux?
The current package definition needs bootstrap binaries, which currently
are only defined for x86_64-linux and i686-linux, so --system=aarch64-linux
cannot work.

Doing --target=aarch64-linux-gnu should work though (untested).

(ins)efraim@3900XT ~/workspace/guix$ time torsocks ./pre-inst-env guix build --no-grafts git-annex --target=aarch64-linux-gnu
guix build: error: gnu/packages/haskell-apps.scm:345:2: git-annex@8.20210903: build system `haskell' does not support cross builds

Interestingly it might be easier to get the haskell-build-system to
support cross compiling than to find the upstream blessed binary for one
of the GHC releases and use that as a bootstrap for later GHC releases
on aarch64.

Hi,

To my knowledge, the system aarch64 is not supported.  The GHC bootstrap
is currently implemented for x86_64 and i686, only.

Moreover, the Haskell build system does not support cross-builds, again
to my knowledge.

There is no mean to compile git-annex for aarch64.  Therefore, it is
expected that it fails.

Cheers,
