Root 6.26.10 did not compile anymore after update to macos Ventura 13.3.1

ROOT Version: 6.26.10
Platform: macos Ventura 13.3.1
Compiler: AppleClang

Dear all,
unfortunately I just updated my MacOS Ventura to the latest version (with the new version of Xcode etc i guess)
When compiling root now I got these errors:

In file included from /Users/mantonello/UHH_Analysis/root-6.26.10/core/base/inc/TQObject.h:42:

Could someone help me to manage to recompile it again?
Before the update I managed to compile the same stable release without any issue.
Thank you so much


Ouch sorry!
I just had a look but I didn’t understood if there is still a fix or not sorry

You can probably build from source (git master branch), but there are still some open issues that need to be fixed.
