Public bug reported: Glibc 2.33 changed the float_t type from double to compiler-defined which is float on s390x:
https://sourceware.org/pipermail/libc-alpha/2021-February/122207.html ... * On s390(x), the type float_t is now derived from the macro __FLT_EVAL_METHOD__ that is defined by the compiler, instead of being hardcoded to double. This does not affect the ABI of any libraries that are part of the GNU C Library, but may affect the ABI of other libraries that use this type in their interfaces. The new definition improves consistency with compiler behavior in many scenarios. ... To not break clucene's ABI accidentally clucene fixed float_t to be double: clucene-core (2.3.3.4+dfsg-1ubuntu1) hirsute; urgency=medium * Fix float_t abi to double ahead of glibc change. -- Dimitri John Ledkov <x...@ubuntu.com> Mon, 01 Feb 2021 10:22:06 +0000 This conflicts with GCC's definition in libreoffice's autopkgtest: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-hirsute/hirsute/s390x/libr/libreoffice/20210215_232647_879ab@/log.gz ... configure: error: Your version of libclucene has contribs-lib missing.
