Bug ID: 101234 Summary: Two tests require en_US.ISO-8859-15 but glibc no longer installs that by default. Product: gcc Version: 11.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: zarniwhoop at ntlworld dot com Target Milestone: --- In 22_locale/codecvt/out/wchar_t/3.cc and 22_locale/codecvt/in/wchar_t/3.cc the tests are only run if dejagnu finds the en_US.ISO-8859-15 locale. I assume that glibc used to install that when installing all locales (e.g. [https://centos.pkgs.org/8-stream/centos-baseos-x86_64/glibc-langpack-en-2.28-155.el8.x86_64.rpm.html] implies that), but recent glibc does not automatically install it. My earliest available old system is using glibc-2.30 and there that locale was not installed when I installed all locales. Manually installing it on a current system with glibc-2.33, the number of expected passes increased by 4 so the tests do still work, it is just that most builders will not run them. If I'm reading the tests correctly, they convert the whole character-set. Perhaps they could be converted to use one of the @euro locales which are still installed automatically by glibc ? I see that at least de_DE@euro and es_ES@euro are in that category and alreadty used by other tests.
