Bug: dovecot 2.3.21.1 fails to build with recent ICU

Hi, dovecot 2.3.21.1 fails to build with ICU 77. There are also reports it does not build with ICU 76 for the same reason: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=284832 There is no issue when built with ICU 75. The failure is this: /bin/bash ../../libtool --tag=CC --mode=link /usr/gcc/14/bin/gcc -std=gnu99 -m64 -O3 -Wno-incompatible-pointer-types -fstack-protector-strong -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -mfunction-return=keep -mindirect-branch=keep -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/usr/openssl/3/include -no-undefined -m64 -o test-fts-icu test-fts-icu.o fts-icu.lo -licui18n ../lib-test/libtest.la ../lib/liblib.la -lsocket -lnsl -lsendfile libtool: link: /usr/gcc/14/bin/gcc -std=gnu99 -m64 -O3 -Wno-incompatible-pointer-types -fstack-protector-strong -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -mfunction-return=keep -mindirect-branch=keep -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/usr/openssl/3/include -m64 -o test-fts-icu test-fts-icu.o .libs/fts-icu.o -licui18n ../lib-test/.libs/libtest.a ../lib/.libs/liblib.a -lsocket -lnsl -lsendfile Undefined first referenced symbol in file ucasemap_utf8ToLower_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) u_strFromUTF8Lenient_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) u_errorName_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) u_cleanup_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) ucasemap_close_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) u_strToUTF8WithSub_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) ucasemap_open_77 .libs/fts-icu.o (symbol belongs to implicit dependency /usr/lib/amd64/libicuuc.so.77) ld: fatal: symbol referencing errors. No output written to test-fts-icu collect2: error: ld returned 1 exit status The workaround is easy: to add -licuuc to LDFLAGS, however it would be great if dovecot builds without any workarounds needed. Thank you. -- +-------------------------------------------+ | Marcel Telka e-mail: marcel(a)telka.sk | | homepage: http://telka.sk/ | +-------------------------------------------+
