Unable to Upgrade qt6-qtbase

[TopHatProductions115new (TopHatProductions115)]

macOS Monterey 12.7.6

Around 1-2 weeks ago, I began to encounter an issue when attempting to upgrade installed ports (port selfupdate, port upgrade outdated). I can no longer upgrade qt6-qtbase. The terminal output reads as follows:

When reviewing main.log, the following lines caught my eye:

:info:configure CMake Error at cmake/QtPublicAppleHelpers.cmake:925 (message):
:info:configure   Qt requires at least version 14 of the platform SDK, you're building
:info:configure   against version 13.1.  Please upgrade.  You can turn this error into a
:info:configure   warning by configuring with -DQT_FORCE_WARN_APPLE_SDK_AND_XCODE_CHECK=ON,
:info:configure   but the build will likely fail.  Use at your own risk.

Should I attempt to build qt6-qtbase for macOS Monterey? Or is there a better solution?

port info qt6-qtbase indicates that it requires darwin 23 (macOS 14) or later. That changed in December, so presumably older versions worked on Monterey. I guess you're supposed to use qt67-* now, but it's bad that there isn't an automatic upgrade path.

Replying to jmroot:

If this is the case, wouldn't this also leave macOS Ventura (13.X) users behind? That version of the OS is still supported by Apple :(

There isn't much I can do about what systems Qt6 supports. There are currently three different ports that support the following Darwin versions:

set qt6::available_versions {
    qt6     {6.8   {24 23}}
    qt67    {6.7   {24 23 22 21}}
    qt64    {6.4   {24 23 22 21 20 19 18}}
}

I agree with Josh that a better "upgrade" path would be helpful for users that had the qt6 port installed on a system where it's no longer supported. I think ​this PR does that from my limited testing, I would appreciate another set of eyes on it before I merge it.
