WINEPREFIX=~/wineprefixes/League3 wine LeagueClient.exe --no-sandbox #call to
unimplemented function on line 229
The LeagueClient.exe alpha client (not the game client) is no longer working,
and has started giving various errors when launched, among them a call to an
unimplemented function.
Getting it installed is a bit elaborate, as it depends on an existing install
of League of Legends:
* Install the normal League of Legends client + game. I have not tried
installing from scratch in a while, and I hear it is tricky. I have a set of
extracted/downloaded files (like 1-3 GB) from earlier, that I install an older
base-version from, and then patch it up to the most recent version by running
the (legacy/normal) client after the first install.
* vcrun2013 via winetricks (not sure if vcrun2015 is required)
At this point the normal/legacy client works, and it can be used to start games
with the game client with very few or no complications at all.
* Installing the alpha LeagueClient.exe (not the game-client) [alpha-client
download as of 2016-11-11:
http://euw.leagueoflegends.com/en/client-update/download ] It is possible that
it might be replaced with a download of the beta-version soon, as the alpha is
about to end.
It should create a new launcher in the root directory of the League install
(usually 'drive_c/Riot Games/League of Legends' called LeagueClient.exe. This
needs to be launched with the --no-sandbox parameter, as it uses (I believe it
was) the chrome webkit/its cef-sandbox, which seems to not work with wine too
well.
* Running the LeagueClient.exe client/launcher. For me, the first launch after
installing opens a progress-window showing a download/install of about 1GB.
After it reaches abouts halfway, the message 
wine: Call from 0x7b43d49c to unimplemented function
api-ms-win-crt-math-l1-1-0.dll.nearbyint, aborting
is produced in the log, and it crashes shortly after (and then tries
relaunching several time, leading to several crashes):
wine: Unhandled page fault on write access to 0x17b74049 at address 0x7bc540e2
(thread 005d), starting debugger...
wine: Unhandled exception 0x80000003 in thread ce at address 0x11ec7223 (thread
00ce), starting debugger...
etc
But either way, previously launching LeagueClient.exe with wine (and the
--no-sandbox parameter) lead to the alpha client starting, patching the game
files if necessary, and being usable for starting games.
Recently (around early november/patch 6.22 ? ), I have not been able to launch
it beyond the startup process. The 1280x720 client window sometimes appears
with a loading symbol, but just briefly before crashing.
The first crash/error on the first launch happens pretty early (line 229 in the
attached log), the rest of the log is mainly the client trying to relaunch and
crashing (or timing out with existing wine instance ?).
