Comment 4 for bug 1828355

Ok, I made a quick test, the --homedir option is recognised and the given directory is created. A config and stdout.txt are created as well. Starting a game and saving one works. The directories ai, save, replays and temp are then created.

But clicking on options results in an error:

Unexpected error during the game
FileSystem::create: could not find file or directory: F:\widelands\widelands-bzr\hgs-homedir\data/locale

Ok, that's not due to this bug, but a different one (maybe related to it). Unfortunately I won't have time to investigate this further this week. Just found this line in wlapplication.cc

i18n::set_localedir(datadir_ + "/locale");

I think the / is the culprit as it seems that this line in options.cd finally creating the localedir doesn't take care of it.

std::unique_ptr<FileSystem> fs(&FileSystem::create(i18n::get_localedir()));

Maybe it should use something like RealFSImpl on the result of get_localedir(). Or that should be done inside set_localedir().

Sorry for not trying it myself. I don't have time at the moment for further experiments. :-(
