GCC 8.x is required to avoid the following error:
cc1plus: error: -Werror=class-memaccess: no option -Wclass-memaccess
If we build without "-Wno-error=class-memaccess" the build should fail
and the upstream requirements were raised from GCC 7 to GCC 8 anyway:
b2f821d3de
The two additional patches are required to avoid build errors like this:
/build/source/Telegram/ThirdParty/qtlottie/src/bodymovin/bmbase.cpp:123:12:

This was needed for my webcam to work with zoom-us. v4l2convert is a
wrapper for apps that only support simple bgr24 or yuv420. For these
apps to support webcams that don’t use those formats, we need to use
LD_PRELOAD to get those symbols. Taken from archlinux wiki:
https://wiki.archlinux.org/index.php/Webcam_setup#V4L1_support
If dropbox can't load libappindicator, it will fallback to using the old
xembed protocol. If you (or your Desktop Environment) are running
something like KDE's XEmbed SNI Proxy, then you'll at least see an icon,
but clicking the icon won't give you menu.
Adding libappindicator to the env allows dropbox to fully integrate with
contemporary status trays, while still falling back to xembed if the
required DBus service is not present.
A recent upgrade of cargo-vendor changed its output slightly, which
broke all cargoSha256 hashes in nixpkgs.
See https://github.com/NixOS/nixpkgs/issues/60668 for more information.
Since then, a few hashes have been fixed in master by hand, but there
were a lot still to do, so I did all of the ones left over with some
scripts I wrote.
The one hash I wasn’t able to update was habitat's, because it’s
currently broken and the build doesn’t get far enough to produce a
hash anyway.
This is technically not needed as the changes only relate to appstream packaging
but as we are rebuilding it anyway due to libqmatrixclient changing, we might as
well.
