Description
qt5-qtdeclarative fails to build with type redefinition error on UChar, this is happening for me on both macOS 10.15.7 / Xcode 12.4 and macOS 11.3 / Xcode 12.5.
Initial definition is in a header from the icu port, which is in the dependency chain of qt5-qtdeclarative.
Error:

hi, I have the same problem. If I try disabling icu I get:
Note: It is not recommended to uninstall/deactivate a port that has dependents as it breaks the dependents. The following ports will break: libxml2 @2.9.10_1 qt5-qtbase @5.15.2_2
which doesn't seem very wise trying to install qt5. Any workaround for this? Thanks a lot

Patches fix the compile problems I ran into, but they are not pretty nor good and should only ever be used as an example of what not to do.

qt513-qtdeclarative is affected by this. Fix to be copied over in https://github.com/macports/macports-ports/pull/15454

that's an icu file:
and it's is conflicting with the one in qt (older version of icu, no doubt).
Something like this:
https://bugs.webkit.org/show_bug.cgi?id=101179
Probably hasn't been rebuilt since icu was updated.
Try disabling icu if it will let you. Otherwise you/me/marcus/somebody needs to find a patch or a fix or a define or a declare or a change in include ordering or --- to get past it.
