Seems to be related to =dev-libs/icu-73.1 , and this change in ICU: https://github.com/unicode-org/icu/commit/2de88f9d9c07f7e693449f94858d96053222acea https://unicode-org.atlassian.net/browse/ICU-21833 2de88f9 in ICU changes UChar* to char16_t* ures.h, but qtwebengine wants to compile with -DUCHAR_TYPE=uint16_t. Looks like a valid compiler error to me, that needs at least a cast. Interestingly, the issue in ICU says that C header files are supposed to stay untouched, but ures.h clearly is a C header file.
Overriding UCHAR_TYPE was removed long time ago, see https://crrev.com/c/2830820.
Created attachment 860182 [details, diff] Patch against =dev-libs/icu-73.1 With this as a user-patch to =dev-libs/icu-73.1 and re-emerging icu, qtwebengine compiles again. But I have no evaluated in depth, if the change has any more consequences. And especially if overriding UChar isn't wanted anymore, this is more of a very temporary patch.
Patch works ok with gcc-13.
