Hi folks, I have been seeing some compiler errors on CentOS 8 like the following: ----------------------------------- /home/rsharpe/src/<some-path>wireshark/epan/packet.c:142:25: error: cast between incompatible function types from ‘void (*)(void *)’ to ‘void (*)(void *, void *)’ [-Werror=cast-function-type] g_slist_foreach(*list, (GFunc)g_free, NULL); ^ cc1: all warnings being treated as errors make[2]: *** [epan/CMakeFiles/epan.dir/build.make:687: epan/CMakeFiles/epan.dir/packet.c.o] Error 1 ---------------------------------- The warning is correct because a GFunc takes two arguments, while g_free takes only one argument. How do I avoid the warning/error? Also, should we fix these things up?
OK, I see that in the latest sources all these seem to have been fixed up using the same techniques I used on the 2.6.2-based source I was working with :-) -- Regards, Richard Sharpe (何以解憂?唯有杜康。--曹操)(传说杜康是酒的发明者) ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
