Good that you found out a package installed on top of vanilla ubuntu 24.04 which can cause this situation. > required_utilities = d.getVar('SANITY_REQUIRED_UTILITIES') > > for util in required_utilities.split(): > > -=-=-=-=-=-=-=-=-=-=-=- > Links: You receive all messages sent to this group. > View/Reply Online (#220053): https://lists.openembedded.org/g/openembedded-core/message/220053 > Mute This Topic: https://lists.openembedded.org/mt/114055527/1997914 > Group Owner: openembedded-core+owner@lists.openembedded.org > Unsubscribe: https://lists.openembedded.org/g/openembedded-core/unsub [raj.khem@gmail.com] > -=-=-=-=-=-=-=-=-=-=-=- >

Installing emacs on Ubuntu 24.04 pulls in emacs-gtk which leads to libgcc-14-dev despite gcc being 13. This breaks libcxx-native and compiler-rt-native builds. We've tried various ways of addressing this buit they don't work. Instead, detect this situation and tell the user to either install or remove a package.
