Hello. I have a question about Fedora's default build flags: -Wp,-U_FORTIFY_SOURCE,-D_FORTIFY_SOURCE=3 -Wp,-D_GLIBCXX_ASSERTIONS Why do we use undocumented -Wp prefix? From manpage:
The preprocessor’s direct interface is undocumented and subject to change, so whenever possible you should avoid using -Wp and let the driver handle the options instead.
According to the Matrix discussion, the prefix was added 19 years ago: https://src.fedoraproject.org/rpms/redhat-rpm-config/c/1518ff2d14377c05ecf7cf9428e42964516883b4 The same build flags used on Ubuntu 24.04 LTS will generate a warning/error:
<command-line>: error: "_FORTIFY_SOURCE" redefined [-Werror] <command-line>: note: this is the location of the previous definition
Maybe it should be replaced with -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=3 -D_GLIBCXX_ASSERTIONS?
