phantomjs-qt-qtbase: build error

[amake (Aaron Madlon-Kay)]

I am unable to build phantomjs-qt-qtbase; log is attached.

[amake (Aaron Madlon-Kay)]

The log says

Warning: The macOS 10.15 SDK does not appear to be installed. Ports may not build correctly.
Warning: You can install it as part of the Xcode Command Line Tools package by running `xcode-select --install'.

But I do have it:

drwxr-xr-x  7 root  wheel  224 Jul 17 19:25 MacOSX11.0.sdk

Reinstalling the Xcode 11.5 CLT doesn't help.

I did notice that Software Update installed the Xcode 12 beta 3 CLT package a few days ago, despite my not asking for it.

• Xcode 11.6 11E708

That's an incorrect warning which is generated because this port changes configure.sdk_version (I think there's a ticket for that but don't have the number handy). It looks like the real issue here is not related to the SDK, but rather some questionable C++ that the compiler rejects.

I find that if I blacklist clang 11 then it falls back to macports-clang-9.0 and the build succeeds.

I had to uncomment the pre-fetch fail relating to #53151 however.

I did not notice this ticket when I reported #62051. At least some of the errors in the log are described in that ticket, and the fact that the port fails to build with Xcode clang 11.5 and later while LLVM clang 9.0 works is consistent with that ticket.

Can this ticket be closed (possibly as duplicate of #62051)? I believe it was resolved by [8cebbb3b6c/macports-ports].
