    Is there a rationale why upstream guix does not offer ucrt?

    1. https://issues.guix.gnu.org/71630:

    I’ve added a new configure flag to set the default MSVCRT to MSVCRT as the default now is UCRT. This default is also changed by Debian, other projects like MSYS2 use a different target triplet for UCRT which is now the default and could be introduced if necessary on GNU Guix.

  5. trevarj commented at 7:42 pm on October 21, 2025: none
    I could submit an upstream Guix patch for this. It will help with build times since the package with ucrt will be in the main substitute servers.

    If we are going to copy-paste this from Guix, and maintain it outself, seems like we should simplify it for our usage? i.e we know we are building winpthreads.

    hebasto commented at 1:20 pm on October 29, 2025:
    We cannot phase out the with-winpthreads? argument, as during the recursive invocation it is unset:https://github.com/bitcoin/bitcoin/blob/f380e6251021cc7aa0c47f564147abea922dc050/contrib/guix/manifest.scm#L154-L157

    It should be possible to inherit the Guix package and then modify arguments to replace `"–with-default-msvcrt=msvcrt" with “”–with-default-msvcrt=ucrt"

    Would it work with the recursion in make-mingw-w64/implementation?

    Forgot about that, so no🤦🏻‍♂️. Will be much better when that PR lands. (See below)

    @hebasto This builds correctly with guix build -f [save below to tmp file]. The native-inputs override solves the issue with recursion.

    What is the plan for adding CI, as that blocks everything here?

    I’m working on it. I have issues with the sqlite package that are not reproducible neither in the nightly builds nor locally.

    UPDATE. See #33764.

    As I understand it, this will produce the cross-compile toolchain using GCC 13. Should we wait on this PR until we have GCC 14] (https://github.com/bitcoin/bitcoin/pull/33775) being as CI for UCRT (https://github.com/bitcoin/bitcoin/pull/33764) will be based on Trixie and GCC 14?

    What is the plan for adding CI, as that blocks everything here?

    The UCRT CI job is up now.

    The UCRT CI job is up now.

    You’ll have to rebase this one and adjust the ci comments in the ci config files, no?

    Thanks! Done.

    Shouldn’t this be removing the other CI (#33764):

    MSVCRT-related CI jobs should be removed from the CI framework once the migration to UCRT is complete.

    Given it’s dropping the other CI, I think this PR should be completing #30210, dropping workarounds, updating any docs, and completing the migration.

    Should this be moved to 32.x, so that there is a bit more time for the Ubuntu/Debian upstream to fix https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1121403 and https://bugs.launchpad.net/ubuntu/+source/mingw-w64/+bug/2106420 ? Otherwise, the only ways to cross-compile with system packages would be guix and Fedora?
