[Message part 1 (text/plain, inline)]

Hi,

On my x86_64 GuixSD machine, using Guix commit
77f921587c6b784e84b98a9f2e9c821f73114340, GNU Hello fails to build for
the armhf-linux target.  It builds for the i686-linux, aarch64-linux,
and mip64el-linux targets.

I'm trying to build it using the following command, invoked from the
Guix source tree:

  ./pre-inst-env guix build --no-substitutes --target=armhf-linux hello

Here are the last few lines of output:

It looks like the configure phase of the derivation that builds
binutils-cross-armhf-linux-2.28 failed because "armhf" is supposedly not
a recognized machine.  However, "armhf-linux" is listed as a supported
platform in the Guix manual ((guix) GNU Distribution), so I expected
this to work.  What's going on here?

GNU Hello successfully builds on my machine for the x86_64-linux,
i686-linux, aarch64-linux, and mips64el-linux platforms (i.e., all of
the other platforms listed as supported in the Guix manual).

The argument to --target must be a GNU triplet, not a Guix “system
type.”

GNU triplets have the form CPU-VENDOR-OS, which often looks like
CPU-KERNEL-OSABI.  In this case, you want

  --target=arm-linux-gnueabihf

HTH!
Ludo’.

Ah, I see!  Thank you.  When I tried again using the target you
suggested, it worked.

I have some follow-up questions, so I've sent a a follow-up email to
guix-devel.
