I don't imagine any proper fix is coming any time soon and I don't plan on working on it myself (other than perhaps the workaround). Thanks for the work-around! I had same issue building qtnetworking with clang-17 and "-Wl,--undefined-version" fixed it.

In a year or so, we'll get the Qt 5 fix and it'll propagate down into Qt5PatchCollection naturally.

Created attachment 872160 [details] build log In a clang-17[default-libcxx] environment, dev-qt/qtgui-5.15.10-r2 will fail to link during emerge with the following error message: ``` ld.lld: error: version script assignment of 'Qt_5.15' to symbol 'qt_version_tag' failed: symbol not defined clang++: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [Makefile:1292: ../../lib/libQt5Gui.so.5.15.10] Error 1 ``` This can be avoided by passing "-Wl,--undefined-version" to LDFLAGS. Attaching logs.
