CTU "error: cannot import unsupported AST node Concept"

[chohc1210]

It seems that c++20 related features are not completed.
Is there any plan or schedule?

Hi,
CodeChecker is "just" an infrastructure for driving these analyzers such as Clang, and maintaining their results. The Clang analyzer engine is a different thing which is out of scope for this project. So I would suggest asking this question from the Clang community, unfortunately we can't answer it here. (Unless a Clang developer can see this discussion, of course :) )

Oh.
Thank for your reply. :)
