Hi,

here's my attempt to update Qt5 packages.

Currently there are two main issues to deal with:

- 5.15.5 changed the URL where they use "-everywhere-opensource-src-" instead of "-everywhere-src-". Changing it directly in qt5-urls breaks the qtbase (Qt6 version of the package). The solution is either to add argument or create qt6-urls.

What would be the best? Checked Qt6 modules on official release URL and there's currently no change in the link atm.

- I need help with building qtwebengine. It's massive beast that fails to build. See the logs attached. I used the patches from LFS where they use Python 3 plus more.

I've been able to build the rest of the packages.

----
Petr

I believe Efraim has pushed 5.15.5 updates to staging already. I can't
find the issue at the moment but from the commit log I see that:

Commit 1218a5ad6912bbfb5f25b324be8b91caf8480793 bumps QT to 5.15.5
Commit 2ca51636511aa897dfac9a32c432f6e56724645b bumps QT to 5.15.4

Closing.  We're now at 5.15.8 on the staging branch.

+Submitted By: Ken Moffat <ken at linuxfromscratch dot org>
+Date: 2022-06-22
+Initial Package Version: From git 5.15 branch.
+Upstream Status: Not applied
+Origin: upstreams and gentoo, Douglas, fedora, self, Arch.
+Description: Allows this to build and work on BLFS-10.1
+Updated on 2021-05-04: add gentoo patch for gcc-11.
+Updated on 2021-06-18: remove fix for graphcycles.cc which is now upstream
+Updated on 2021-08-13: add fixes to compile and let browsers using it work on glibc-2.34
+Updated on 2021-11-22: fixes for qtwebengine-5.15.7.
+Updated on 2022-01-13: reduced to what still applies to 5.15.8.
+Updated on 2022-06-22: patches from Arch via gentoo to use python3, one modified for BLFS.
+The lingering arm and mips patches from an earlier fedora patchset have been dropped.
+Include a patch for gcc12.
+
+References to old patches, in the order they were applied, are retained to
+assist people wishing to review what has changed compared to previous versions.
+
+
+First, a patch from gentoo to avoid the build from a git version requiring
+git, although the .git directories are still required.
+
+generate_gni.sh: update_readme() runs git at the end of process, prevent it.
+
+Thanks-to: Georgy Yakovlev <gyakovlev@gentoo.org>

+Second was a patch from fedora to make some web pages render when glibc-2.33
+is used. Upstream fixed qtwebengine-5.15.6 slightly differently
+
+Third, a patch from Douglas R. Reno (renodr at linuxfromscratch dot org):
+
+When building qtwebengine where libxml2 has been built before ICU has been 
+installed, a build failure will occur because QtWebEngine will attempt to use
+it's internal version of libxml2, which *was not* patched against API changes
+in ICU-68.1+. These changes involved removing the TRUE and FALSE macros, and
+the official documentation states that developers should use 'true' and 'false'
+instead, of course making sure that 'stdbool.h' is included so that the compiler
+can actually find those boolean values. Since Chromium's internal version of ICU
+is older than ours, it's not a problem when building with the internal version 
+of ICU. Users who have installed ICU before libxml2 are exempt from running into
+this issue.

+Fifth were some fixes from upstream abseil to build with glibc-2.34.
+The first part has been fixed slightly differently in chromium in
+qtwebengne-5.15.8, I assume the remainder are not actually needed for
+chromium.
+
+Sixth was a patch from Fedora to compile breakpad on glibc-2.34, fixed
+slightly differently in chromium in qtwebengine-5.15.8
+
+Seventh: a patch from fedora to handle time64 syscalls, fixed up to apply
+to 5.15.7 (parts were upstream but in a slightly different order).
+I have now removed the arm_linux_syscalls.h and mips_linux_syscalls.h
+changes since BLFS cannot use these.
