Linux Appimage can't detect input from ibus in Linux Mint 22

[thantzarni77]

In Linux Mint 21.3, the Appimage works ok with ibus. But in Linux Mint 22, it doesn't detect any inputs from ibus.

Error Message

The AppImage version is also problematic on my Fcitx5 setup too on Ubuntu 24.04 Wayland, seems like the contained binary is linked to a non-current or modified version of these input backend libraries during compilation, hence the undefined symbols.

The solution on my machine is to compile the program manually. But, doing this way you wouldn't have a complete installation like you would when using AppImage or distro package, there are things that you may need to supply separately like MoonScript and copying the built-in automation scripts around. And it might also unstable depending on which branch and commit, so far branch feature at commit https://github.com/arch1t3cht/Aegisub/commit/bf20c62e6b3d88a3e425fc05d26fd2b40e652775 is stable enough for me.

Can you guide me how to compile it since i'm not familiar with compiling?

[EmiyaSyahriel]

I am not familiar with Linux Mint since I uses Ubuntu since beginning, but since Linux Mint is based on Ubuntu, I think the way the manage package should be similar (Linux Mint also uses apt, am I right?).

By the way, all of this steps is available on this repo's homepage, I just made it more verbose here.

Installing dependencies

I have to warn you that these packages were from apt show aegisub (the one at the Ubuntu repo) dependencies, because I did not remember what packages I already have in my system and the one that I need install at the time I compile, and these packages might require a lot of storage space.

And if you fail to setup or compile with an error like missing library : [library name] or missing dependency : [library name], you can just search it by apt search [library name] and you can just install them through sudo apt install [library name from apt search list] and then re-run the process.

Here is the list:

• gcc / llvm ( gcc is on build-essential package )
• meson
• git
• ninja
• ffms2
• lua & luajit
• fftw3
• fontconfig
• libass
• openal
• boost ( chrono, filesystem, thread, locale, regex modules )
• zlib
• either alsa, portaudio, pulseaudio development library
• wxWidgets

Here is the shell command to install all of these dependencies :

sudo apt install build-essential meson ninja ffmpeg git libffms2-dev liblua5.1-0-dev libluajit5.1-dev libfftw3-dev libfontconfig-dev libass-dev libboost-chrono-dev libboost-filesystem-dev libboost-thread-dev libboost-locale-dev libboost-regex-dev libpulse-dev libopenal1-dev libwxbase3.2-1t64 libwxgtk3.2-dev

Cloning the repository

• Make a directory somewhere reachable (e.g /home/username/app_building/aegisub)
• Open your terminal and execute:

  cd "/home/username/app_building/aegisub"
  git clone -b feature --recurse-submodules -j8 https://github.com/arch1t3cht/Aegisub

  You can change the -b feature to other branch like -b workarounds if you want to.

Now you have cloned (downloaded) the source code repository, so you can build the app from the source code. Do not close the terminal yet.

Compiling the app

• From terminal, go to the source code repository root folder by executing:

  cd "Aegisub"

• Now let's start setting up the project by executing :

  meson setup build -Ddefault_library=static --buildtype=release

• If there is no error during configuration step, you can now start compiling the source code to executable by executing :

  cd build
  ninja

• If there is no error during compilation step, you can install the compiled app by executing:

  ninja install

  or, if there is some permission error:

  sudo ninja install

  Compiling finished

  Now you have it. You can just run the app from the terminal by executing :

  aegisub

  But if you want to launch it the graphical way, the install script should also install a .desktop file for your desktop environment launcher to list and launch.

I appreciate it. Compiling was successful with a single attempt.
