The “.x86_64-linux” in the Hydra job name above means that it’s cross-built from x86_64; that’s why the store file name is different from the one you have on i686. The failure on i686 is a timeout while running libgc’s test suite (the native i686 build): https://hydra.gnu.org/build/1820051 --8<---------------cut here---------------start------------->8--- make check-TESTS make[2]: Entering directory '/tmp/guix-build-libgc-7.6.0.drv-0/gc-7.6.0' make[3]: Entering directory '/tmp/guix-build-libgc-7.6.0.drv-0/gc-7.6.0' PASS: leaktest PASS: cordtest PASS: smashtest PASS: hugetest PASS: middletest PASS: threadleaktest PASS: threadkey_test PASS: subthreadcreate_test PASS: initsecondarythread_test PASS: staticrootstest PASS: realloc_test PASS: test_cpp PASS: disclaim_test PASS: disclaim_bench building of `/gnu/store/yk15c9c5vjny19pw30zkygf2vzy6zp7h-libgc-7.6.0.drv' timed out after 3600 seconds of silence --8<---------------cut here---------------end--------------->8--- I’ve just tried: ./pre-inst-env guix build -e '(@@ (gnu packages commencement) guile-final)' \ -s i686-linux -K on my x86_64 box and it passes without a problem.
