The libieee.a library is therefore not shipped anymore. perl correctly detects that it is not available and build fine, but it introduces a small symbol change, as _LIB_VERSION is provided by libieee.a. The solution for it to work with both glibc 2.27 and older version is to mark the symbol as optional. This should not be a problem, as a package which needs the "ieee" library has to link against libieee.a which will then provide the symbols. In addition no such package perl package has been found during the archive rebuild. Therefore the following simple patch should be enough to fix the issue: --- perl-5.26.1/debian/libperl5.26.symbols +++ perl-5.26.1/debian/libperl5.26.symbols @@ -1809,7 +1809,7 @@ XS_utf8_unicode_to_native@Base 5.26.0~rc1 XS_utf8_upgrade@Base 5.26.0~rc1 XS_utf8_valid@Base 5.26.0~rc1 - _LIB_VERSION@Base 5.26.0~rc1 + (optional)_LIB_VERSION@Base 5.26.0~rc1 boot_DynaLoader@Base 5.26.0~rc1 cv_flags_names@Base 5.26.0~rc1 first_sv_flags_names@Base 5.26.0~rc1 Could you please apply it in the next upload?
