Binary repository problems with today's GCC and QT upgrade

Created by: ollieparanoid

GCC

TL;DR: run pmbootstrap update to fix pmbootstrap trying to compile gcc-armhf or gcc-aarch64.

GCC has been updated in upstream in Alpine with a bunch of new patches on top, so our cross compilers need to be updated as well (thanks @MartijnBraam for doing that in #1456).

Two problems:

• The official mirror of the sources of GCC is down, hence users can't compile the packages themselves right now (someone could probably find a mirror to the 6.4.0 patches tarball and use that instead by replacing the source in the APKBUILD)
• The package does not build in strict mode, it tries to install build-base-armhf when trying to build gcc-armhf. However with the normal pmbootstrap -y zap; pmbootstrap build gcc-armhf (where pmbootstrap does the dependency resolution, not apk), it appears to be compiling.

The binary package building PC has the sources in the cache, and I'm building the packages there right now to make them available for all postmarketOS users ASAP. As strict mode can't be used right now, I'm not using the regular repository build script, but the workaround described above.

QT

Alpine has also updated their QT version from 5.9 to 5.10. This means, we need to update our aports to use the new QT version as well, and then recompile them. Plasma Mobile can probably not be installed right now because of that. I'm on it.

Note: also some packages have been renamed in Alpine for consistency, e.g.

community/{qt5-websockets => qt5-qtwebsockets}

TODOs

• compile and upload binary packages for gcc cross compilers

run pmbootstrap update to get the new packages if pmbootstrap tries to build gcc-armhf or gcc-aarch64

• update our QT packages in the pmbootstrap repository to 5.10: https://github.com/postmarketOS/pmbootstrap/commit/6c6d0d3e28270afe699692fbf579fdcf798a314d
• bump pkgrels of KDE packages of private API users: https://github.com/postmarketOS/pmbootstrap/commit/676d22fd8ad4fe3f9d738addae94e6f4ae9121e8
• build binary packages (build is running right now!)
  • Almost all QT packages have been rebuilt already. qt5-qtwebengine is failing, which is needed for LuneOS UI (not for Plasma Mobile)
  • KDE packages still need to be rebuilt as of writing
  • See which packages have been built here: http://postmarketos.brixit.nl/
  • Run pmbootstrap update to make your copy of pmbootstrap aware of the latest packages that have been built (updates the APKINDEX)
• fix gcc-* not compiling in strict mode (#1468)
