I did this [halogen@enigmatic cyrus-imapd-3.2.5]$ export CFLAGS="-g -O2 -Wall -Wextra -Werror -Wl,--as-needed" [halogen@enigmatic cyrus-imapd-3.2.5]$ export CXXFLAGS="-g -O2 -Wall -Wextra -Werror -Wl,--as-needed" then started again from `autoreconf -i` After the configure command, the "build info" section at the end of the output said: Build info: shared: yes static: no cflags: -g -O2 -Wall -Wextra -Werror -Wl,--as-needed cxxflags: -g -O2 -Wall -Wextra -Werror -Wl,--as-needed libs: -ljansson -lresolv -lsrs2 -L/usr/lib -lmysqlclient -lpthread -lz -lm -ldl -lssl -lcrypto -lpcre -lpcreposix -lsrs2 -lz -lxml2 -lical -licalss -licalvcal -lsqlite3 ldflags: -Wl,-rpath,/usr/local/cyruslibs/lib -Wl,-rpath,/usr/local/cyruslibs/lib/x86_64-linux-gnu unit tests (cunit): I then ran `make` and this is the error that showed up: gcc -DHAVE_CONFIG_H -I. -I/home/halogen/cyrus-imapd-3.2.5/com_err/et -I. -I./lib -I. -I./lib -DLIBEXEC_DIR=\"/usr/local/libexec\" -DSBIN_DIR=\"/usr/local/sbin\" -DSYSCONF_DIR=\"/etc\" -DHAVE_CONFIG_H -I/usr/include/libxml2 -I/usr/local/include -I/usr/local/include -D_FORTIFY_SOURCE=2 -mtune=i686 -O2 -pipe -g -fvisibility=hidden -I/usr/include/chardet -I/usr/include/mysql -fPIC -g -O2 -Wall -Wextra -Werror -Wl,--as-needed -MT master/master.o -MD -MP -MF $depbase.Tpo -c -o master/master.o master/master.c &&\ mv -f $depbase.Tpo $depbase.Po master/master.c: In function 'do_prom_report': master/master.c:2172:5: error: ignoring return value of 'ftruncate' declared with attribute 'warn_unused_result' [-Werror=unused-result] 2172 | ftruncate(fd, buf_len(&report)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[2]: *** [Makefile:5187: master/master.o] Error 1 make[2]: Leaving directory '/home/halogen/cyrus-imapd-3.2.5' make[1]: *** [Makefile:6897: all-recursive] Error 1 make[1]: Leaving directory '/home/halogen/cyrus-imapd-3.2.5' make: *** [Makefile:3212: all] Error 2 Here is the full make output: https://pastebin.com/vSb1PRSP ------------------------------------------ Cyrus: Devel Permalink: https://cyrus.topicbox.com/groups/devel/Tf544987d7d6a54fd-M0a3988b145786b5afb641a23 Delivery options: https://cyrus.topicbox.com/groups/devel/subscription
