Bug#1108687: dolphin-emu: changing the system language does not work

[Lucas Nussbaum]

Package: dolphin-emu
Version: 2503+dfsg-1
Severity: normal

Hi,

I tried to change the system language to french. This does not work:

according to strace, dolphin looks for translations in
[pid 299342] openat(AT_FDCWD, "/usr/share/games/dolphin-emu//../locale/fr/LC_MESSAGES/dolphin-emu.mo", O_RDONLY) = -1 ENOENT (Aucun fichier ou dossier de ce nom)
while it is installed in /usr/share/locale/fr/LC_MESSAGES/dolphin-emu.mo

the relevant code is:
static bool TryInstallTranslator(const QString& exact_language_code)
{
  for (const auto& qlang : FindPossibleLanguageCodes(exact_language_code))
  {
    std::string lang = qlang.toStdString();
    auto filename =
#if defined _WIN32
        fmt::format("{}/Languages/{}.mo", File::GetExeDirectory(), lang)
#elif defined __APPLE__
        fmt::format("{}/Contents/Resources/{}.lproj/dolphin-emu.mo", File::GetBundleDirectory(),
                    lang)
#elif defined LINUX_LOCAL_DEV
        fmt::format("{}/../Source/Core/DolphinQt/{}/dolphin-emu.mo", File::GetExeDirectory(), lang)
#else
        fmt::format("{}/../locale/{}/LC_MESSAGES/dolphin-emu.mo", DATA_DIR, lang)
#endif

a workaround is:
sudo ln -s /usr/share/locale /usr/share/games/locale

but it's probably a matter of either installing the files in the correct
path, or patching dolphin so that it searches for translation in the
correct path.

Best,

Lucas
