 Priority:  Normal                         |  Milestone:
Component:  ports                          |    Version:  2.10.5
 Keywords:  CXX C++ compiler, M3 Sequoia.  |       Port:
-------------------------------------------+--------------------
 I am running Sequoia 15.2 on a Mini M2 and when I tried to upgrade
 outdated ports, I get the error that ports cannot find my C++ compiler:
 :info:configure Error when bootstrapping CMake:
 :info:configure Cannot find appropriate C++ compiler on this system.
 :info:configure Please specify one using environment variable CXX.
 :info:configure See cmake_bootstrap.log for compilers attempted.

 This error is for Cmake but the same error happens no make what I try to
 update or install.  I tried setting CXX to clang but that did not help and
 I have never had to set the compiler variable before.  Nor do I need to on
 other systems, albeit with older processors than this one.

 What is going on here and how do I get back to the system setup I once
 had?  Do I really need to wipe out Macports and start from scratch?
 Thanks,
 Rob
