Sudden 'type_traits' file not found"

angela2016

Hi,

things were running fine until 15min ago. I had a segfault with my program (it happens) and tried to run the program again from Qt Creator, but got the error "fatal error: 'type_traits' file not found". I haven't changed anything, but now I can't even run a completely new program, not with any of my Qt versions. Here's the output on a fresh project:

Hi,
I actually solved it by installing a different g++ version via

sudo apt install g++-14

Apparently clang found version 14 and wanted to use it but only 13 was installed. Don't asked me why. I also don't really know if that was the right way to solve it but it works so far.
