Hi I want to contribute to guix with patches and at the same time keep my GuixSD on 0.15. To archive this I created and followed the following guide in GuixSD in Qemu: https://gitlab.com/swedebugia/guix-notes/blob/master/BUILD.org Following it Guix 21335fdbec68b4cfb19d8a0ae0877ec81c84ad9c builds fine. BUT running make check I got a lot of failed tests and no testlog: makeĀ  check-recursive make[1]: Entering directory '/home/sdb/guix-tree' Making check in po/guix make[2]: Entering directory '/home/sdb/guix-tree/po/guix' make[2]: Leaving directory '/home/sdb/guix-tree/po/guix' Making check in po/packages make[2]: Entering directory '/home/sdb/guix-tree/po/packages' make[2]: Leaving directory '/home/sdb/guix-tree/po/packages' make[2]: Entering directory '/home/sdb/guix-tree' Compiling Scheme modules... makeĀ  check-TESTS check-local make[3]: Entering directory '/home/sdb/guix-tree' make[4]: Entering directory '/home/sdb/guix-tree' PASS: tests/base16.scm SKIP: tests/base32.scm PASS: tests/base64.scm SKIP: tests/cpio.scm PASS: tests/pki.scm PASS: tests/print.scm PASS: tests/sets.scm PASS: tests/modules.scm PASS: tests/gnu-maintenance.scm PASS: tests/substitute.scm FAIL: tests/builders.scm FAIL: tests/derivations.scm PASS: tests/glob.scm FAIL: tests/grafts.scm FAIL: tests/ui.scm PASS: tests/status.scm PASS: tests/records.scm FAIL: tests/processes.scm PASS: tests/upstream.scm PASS: tests/combinators.scm PASS: tests/discovery.scm PASS: tests/utils.scm PASS: tests/build-utils.scm FAIL: tests/packages.scm SKIP: tests/snix.scm FAIL: tests/hackage.scm FAIL: tests/cran.scm FAIL: tests/elpa.scm FAIL: tests/texlive.scm FAIL: tests/store.scm FAIL: tests/monads.scm make[4]: Leaving directory '/home/sdb/guix-tree' make[3]: Leaving directory '/home/sdb/guix-tree' make[2]: Leaving directory '/home/sdb/guix-tree' make[1]: Leaving directory '/home/sdb/guix-tree' -- Cheers Swedebugia
