I haven't been able to build guix from a local checkout lately: $ git describe --match=v'*' v1.0.1-13415-g0557618dbe $ git clean -dfx $ guix environment --pure guix [env]$ ./bootstrap && ./configure --localstatedir=/var && make -j4 check ++ find po/doc -type f -name 'guix-manual*.po' ... make[4]: Leaving directory '/home/vagrant/src/guix-workspace/po/guix' rm -f en@quot.gmo && /gnu/store/p50cw1g05g566bkbr6ylcibqffhha8w4-profile/bin/msgfmt -c --statistics --verbose -o en@quot.gmo en@quot.po make[5]: Leaving directory '/home/vagrant/src/guix-workspace/po/guix' make[4]: Leaving directory '/home/vagrant/src/guix-workspace/po/guix' rm -f en@boldquot.gmo && /gnu/store/p50cw1g05g566bkbr6ylcibqffhha8w4-profile/bin/msgfmt -c --statistics --verbose -o en@boldquot.gmo en@boldquot.po en@quot.po:4573: format specifications in 'msgstr[0]' are not a subset of those in 'msgid_plural' /gnu/store/p50cw1g05g566bkbr6ylcibqffhha8w4-profile/bin/msgfmt: found 1 fatal error en@quot.po: 938 translated messages. make[3]: *** [Makefile:202: en@quot.gmo] Error 1 make[3]: *** Waiting for unfinished jobs.... en@boldquot.po:4591: format specifications in 'msgstr[0]' are not a subset of those in 'msgid_plural' /gnu/store/p50cw1g05g566bkbr6ylcibqffhha8w4-profile/bin/msgfmt: found 1 fatal error en@boldquot.po: 938 translated messages. make[3]: *** [Makefile:202: en@boldquot.gmo] Error 1 make[3]: Leaving directory '/home/vagrant/src/guix-workspace/po/guix' make[2]: *** [Makefile:239: stamp-po] Error 2 make[2]: Leaving directory '/home/vagrant/src/guix-workspace/po/guix' make[1]: *** [Makefile:4904: check-recursive] Error 1 make[1]: Leaving directory '/home/vagrant/src/guix-workspace' make: *** [Makefile:5372: check] Error 2 This has been several days at least, haven't tried to bisect the issue... I've heard that some people can't reproduce it... "guix pull" from the same commit works fine, but obviously takes a lot more CPU and human cycles to run guix pull every change I want to test. live well, vagrant
