I'm using gnulib 6ccfbb4ce5d4fa79f7afb48f3648f2e0401523c3 from a few days ago.
After upgrading to Fedora 29, the glibc-langpack-fr locale is no longer installed by default. This causes many tests to fail silently: ./gnulib/tests/test-suite.log:FAIL: test-btowc1.sh ./gnulib/tests/test-suite.log:FAIL: test-btowc2.sh ./gnulib/tests/test-suite.log:FAIL: test-c-strcase.sh ./gnulib/tests/test-suite.log:FAIL: test-mbrtowc1.sh ./gnulib/tests/test-suite.log:FAIL: test-mbrtowc2.sh ./gnulib/tests/test-suite.log:FAIL: test-mbrtowc3.sh ./gnulib/tests/test-suite.log:FAIL: test-mbrtowc4.sh ./gnulib/tests/test-suite.log:FAIL: test-mbsrtowcs1.sh ./gnulib/tests/test-suite.log:FAIL: test-mbsrtowcs2.sh ./gnulib/tests/test-suite.log:FAIL: test-mbsrtowcs3.sh ./gnulib/tests/test-suite.log:FAIL: test-mbsrtowcs4.sh ./gnulib/tests/test-suite.log:FAIL: test-setlocale1.sh ./gnulib/tests/test-suite.log:FAIL: test-wcrtomb.sh The failures are completely silent. It seems as if about 6 months ago it used to print an error message: Skipping test: no traditional french locale is installed But for some reason that is no longer printed: $ LC_ALL=fr_FR ./test-btowc 1 $ echo $? 1 (The same applies to Japanese and Chinese language packs for other tests) Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-builder quickly builds VMs from scratch http://libguestfs.org/virt-builder.1.html
