Hi!

Some more info, still no full picture.

TL;DR: 28dc10a4 breaks the cross build on master (i.e. reverting it
fixes the cross build), but core-updates has 28dc10a4 and there the
cross build works.  So cross building with 28dc10a4 depends on something
else that is in core-updates which is missing from master.

Progress at

    https://gitlab.com/janneke/guix

branches v9 and v9-core.

My v9 mingw patch set rebased on current master cannot cross build
readline

    ./pre-inst-env guix build --target=i686-w64-mingw32 readline
    ...
    @ build-failed /gnu/store/m6gq2xz5kd3vn4zm1i0i6j0immlgyhmg-make-boot0-4.1.drv - 1 builder for `/gnu/store/m6gq2xz5kd3vn4zm1i0i6j0immlgyhmg-make-boot0-4.1.drv' failed with exit code 1
    cannot build derivation `/gnu/store/1fjnm2x2az4z4qaz3bad5p5zbygf5wqs-gcc-cross-boot0-4.9.3.drv': 1 dependencies couldn't be built
    guix build: error: build failed: build of `/gnu/store/1fjnm2x2az4z4qaz3bad5p5zbygf5wqs-gcc-cross-boot0-4.9.3.drv' failed

Should that make-boot0 cross-build cross succeed...

   ./pre-inst-env guix build --target=x86_64-linux-gnu make-boot0
   guix build: error: make-boot0: unknown package

hmm, how to find out?...or should in not happen and in that case, what
erroneously makes it happen?

Reverting commit

    commit 28dc10a455689c807abc9241ed1094d902a9d9fa
    Author: Ludovic Courtès <ludo@gnu.org>
    Date:   Sun May 29 23:15:14 2016 +0200

        gnu: glibc: Refer to the target kernel headers when cross-compiling.

makes the make-boot0 error go away, readline and guile.exe cross build.
I don't know how to find out if the make-boot0 build succeeded, or did
not happen?

However I have rebased onto core-updates, which also has commit 28dc10a4,
and there readline and guile.exe cross build succeed.

So, last week I spent cherry-picking patches from core-updates onto
master in an effort to investigate what's going on.

Sofar I have tried

    fb341ca gnu: commencement: Disable Texinfo tests during bootstrap.
    461513b profiles: 'profile-derivation' now honors #:system.
    0f24c8d gnu: perl: Do not retain references to GCC & co.

and have run almost out of inspiration what to try looking at the diff
between v9 and v9-core, I have now added

    9e574f6 gnu: glibc: Update to 2.23.

and am looking at another Guile build...we'll see.
Greetings,
Jan
