Created attachment 872358 [details, diff] qtwebengine-5.15.10_p20230815-clang-17-p1.patch Patch qtwebengine-5.15.10_p20230815-orig/src/3rdparty/chromium/third_party/perfetto/include/perfetto/ext/base/circular_queue.h to update it to the current version from upstream: https://github.com/google/perfetto/raw/master/include/perfetto/ext/base/circular_queue.h
Created attachment 872359 [details, diff] qtwebengine-5.15.10_p20230815-clang-17-p2.patch Add from upstream: https://github.com/google/perfetto/raw/master/include/perfetto/ext/base/sys_types.h
Created attachment 872360 [details, diff] qtwebengine-5.15.10_p20230815-clang-17-p3.patch Update qtwebengine-5.15.10_p20230815/src/3rdparty/chromium/third_party/perfetto/include/perfetto/ext/base/utils.h to a slightly stripped down version from upstream: https://github.com/google/perfetto/raw/master/include/perfetto/ext/base/utils.h and add a stripped down version of utils.cc from upstream: https://raw.githubusercontent.com/google/perfetto/master/src/base/utils.cc
(In reply to ppw0 from comment #0) > In a clang-17[default-libcxx] environment, qtwebengine-5.15.10 will fail to > compile with the following error(s): Thanks for reporting. A workaround is to create the directory /etc/portage/patches/dev-qt/qtwebengine-5.15.10_p20230815 and add the attached patches to this directory: # ls -al qtwebengine-5.15.10_p20230815-clang-17-p?.patch -rw-r--r--. 1 root root 5604 Oct 8 21:29 qtwebengine-5.15.10_p20230815-clang-17-p1.patch -rw-r--r--. 1 root root 1737 Oct 8 21:29 qtwebengine-5.15.10_p20230815-clang-17-p2.patch -rw-r--r--. 1 root root 11535 Oct 8 21:29 qtwebengine-5.15.10_p20230815-clang-17-p3.patch # The patches update template <class T> class CircularQueue { class Iterator { } } from upstream: https://github.com/google/perfetto/ and some other stuff from upstream to allow it to compile and link with clang 17.0.2
qtwebengine-5.15.11_p20230927 builds fine with clang 17.0.2 with no additional patches.
