I'm getting the strange error in $SUBJECT in an upstream CI job that is targetting Fedora rawhide. I'm guessing it is something related to the recent changes to set the _FOTIFY_SOURCE value to 3 instead of 2, but not sure what.
What I'm finding especially bizarre is that I can't reproduce it on rawhide myself, despite using the exact same package versions and base container. I can't even figure out which particular component is emitting this error message string. My only thought is that perhaps it could be ccache related, since upstream CI has ccache enabled and the cache is preserved across CI pipelines. That could explain why I can't reproduce myself. My app has a config.h file used by all sources that does #if !defined _FORTIFY_SOURCE && defined __OPTIMIZE__ && __OPTIMIZE__ # define _FORTIFY_SOURCE 2 #endif but the -D_FORTIFY_SOURCE=3 set by RPM in CFLAGS on the gcc command line ought to override this fine. $ gcc -Ilibvirt-glib/libvirt-glib-1.0.so.0.4000.0.p -Ilibvirt-glib -I../libvirt-glib -I. -I.. -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/include/sysprof-4 -fdiagnostics-color=always -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -std=gnu99 ...snip many -Wxxx flags... -fexceptions -fasynchronous-unwind-tables -fipa-pure-const -fstack-protector-strong -O2 -flto=auto -ffat-lto-objects -fexceptions -g -grecord-gcc-switches -pipe -U_FORTIFY_SOURCE -Wp,-U_FORTIFY_SOURCE -Wp,-D_FORTIFY_SOURCE=3 -Wp,-D_GLIBCXX_ASSERTIONS -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -fstack-protector-strong -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -fPIC -pthread '-DLOCALEDIR="/usr/share/locale"' '-DDATADIR="/usr/share"' -DLIBVIRT_GLIB_BUILD -DGLIB_VERSION_MIN_REQUIRED=GLIB_VERSION_2_48 -DGLIB_VERSION_MAX_ALLOWED=GLIB_VERSION_2_48 -MD -MQ libvirt-glib/libvirt-glib-1.0.so.0.4000.0.p/libvirt-glib-error.c.o -MF libvirt-glib/libvirt-glib-1.0.so.0.4000.0.p/libvirt-glib-error.c.o.d -o libvirt-glib/libvirt-glib-1.0.so.0.4000.0.p/libvirt-glib-error.c.o -c ../libvirt-glib/libvirt-glib-error.c ../libvirt-glib/libvirt-glib-error.c: error: -D_FORTIFY_SOURCE defined but value is too low [-Werror] cc1: all warnings being treated as errors So does anyone know what this error message would be coming from, and more importantly how to make it go away :-) With regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :| _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
