Message : Add CI checks for OpenBSD (#1326) Initially 6.9 and 7.1 had been added, however due to some issues (you can read about them below) 6.9 had been disabled. netbsd 6.9 does not have correct library namings for autotools: 2022-08-17T04:59:58.8339420Z libtool: link: (cd ".libs" && rm -f "libevent.so.1.0" && ln -s "libevent-2.2.so.1.0" "libevent.so.1.0") $ grep ^library_names= libevent.la· library_names='libevent-2.2.so.1.0 libevent.so.1.0' # And this is wrong, it should be: libtool: link: (cd ".libs" && rm -f "libevent-2.2.so.1" && ln -s "libevent-2.2.so.1.0.0" "libevent-2.2.so.1") libtool: link: (cd ".libs" && rm -f "libevent.so" && ln -s "libevent-2.2.so.1.0.0" "libevent.so") library_names='libevent-2.2.so.1.0.0 libevent-2.2.so.1 libevent.so' **And I think that 7.1 should also fail, however it has system-wide libevent installed with evdns in the libevent.so** Also there are some issues with `TEST_EXPORT_SHARED` test, because of libraries naming: 2022-09-13T06:38:29.2150790Z [test-export] test for install tree(in system-wide path) 2022-09-13T06:38:29.2151500Z [test-export] fail: link core and run core expects success but gets failure. 2022-09-13T06:38:29.2063870Z /usr/bin/cc CMakeFiles/test-export.dir/test-export.c.o -o test-export -L/usr/local/lib -Wl,-z,origin,-rpath,/usr/local/lib -levent_core-2.2 -lpthread -Wl,-rpath-link,/usr/X11R6/lib:/usr/local/lib· 2022-09-13T06:38:29.2152190Z ld: error: unable to find library -levent_core-2.2 2022-09-13T06:38:28.3915680Z -- Install configuration: "Release" 2022-09-13T06:38:28.3916700Z -- Up-to-date: /usr/local/lib/libevent_core-2.2.so.1.0.0 2022-09-13T06:38:28.3917110Z -- Up-to-date: /usr/local/lib/libevent_core-2.2.so.1 2022-09-13T06:38:28.3917480Z -- Up-to-date: /usr/local/lib/libevent_core.so # no libevent_core-2.2.so So I have to disable it too.
