Current tdesktop.patch (just used it to build version 1.7.0.r7.g63fc55263)

Note: you should replace sha256 for this file in PKGBUILD with 'SKIP'

Also owned the package and fixed the checksum, should work without manual fixes now

I solved the problem by the following steps: 1. Run makepkg to apply existing successful patches. 2. Edit Telegram/SourceFiles/core/launcher.cpp according to the tdesktop.patch: add 3 lines in Launcher::exec() and change a macro from #ifndef OS_MAC_OLD to #if !defined(Q_OS_MAC) && QT_VERSION >= QT_VERSION_CHECK(5, 6, 0). 3. Generate the correct patch by git diff > tdesktop.patch and replace the old one with this, and editing the sha256sums accordingly.

@bakatrouble: that hunk also results in build failure, or I'm not editing tdesktop.patch correctly.

To fix the tdesktop.patch file to work with current source code replace the second chunk (for Telegram/SourceFiles/core/launcher.cpp) with following snippet:

--- a/Telegram/SourceFiles/core/launcher.cpp
+++ b/Telegram/SourceFiles/core/launcher.cpp

    initHook();
 }

I've disowned the package because I don't have enough time to prepare and maintain proper patches. Further reliance on those from the official repository, in the long run, won't work.

If someone has enough time and determination, I encourage to play with the package ;)

Please note:

qt5-imageformats is a mandatory dependency for displaying stickers so it should be marked as normal dependency instead of makedep

@spacepluk, I can't confirm, check if you have the latest version of the PKGBUILD.

It doesn't build here. It first complains about the sums, then a patch fails to apply.

@Musikolo, ou so that's the problem ;) I don't remember exactly the way, but in the system tray options/preferences you can mark Telegram to show the icon always/never/automatic - play around there and you will find what you need ;)
