Run the game Summertime Saga with nix-alien

[UlyssesZh]

Summertime Saga is a free-to-download game. There is a launcher script, which sets LD_LIBRARY_PATH and runs a binary program. I tried to remove the LD_LIBRARY_PATH setting and replace the binary program launching with nix-alien. Then, when it runs, it immediately throws this error and exit:

Traceback (most recent call last):
  File "/home/ulysses/apps/games/SummertimeSaga/SummertimeSaga-0-20-15-pc/SummertimeSaga.py", line 198, in <module>
    main()
  File "/home/ulysses/apps/games/SummertimeSaga/SummertimeSaga-0-20-15-pc/SummertimeSaga.py", line 195, in main
    renpy.bootstrap.bootstrap(renpy_base)
  File "/home/ulysses/apps/games/SummertimeSaga/SummertimeSaga-0-20-15-pc/renpy/bootstrap.py", line 273, in bootstrap
    renpy.display.presplash.start(basedir, gamedir)
  File "/home/ulysses/apps/games/SummertimeSaga/SummertimeSaga-0-20-15-pc/renpy/display/presplash.py", line 64, in start
    pygame_sdl2.display.init()
  File "src/pygame_sdl2/display.pyx", line 96, in pygame_sdl2.display.init
pygame_sdl2.error.error: No available video device

I then tried to set the env var SDL_VIDEODRIVER to various different things, and still couldn't fix it.

I think there may be some libraries that I need to manually add to nix-alien call, but I am not sure. My other guess is that the so libraries used by this program (provided by the game in a lib subdir) may be different from those from nixpkgs, so this issue may be related to #77. Could you please see whether there is a way to make the game run?

PS: The game is NSFW. Run it in private area.

Please take a look at https://github.com/thiagokokada/nix-alien#limitations for how to manually add libraries.

How to know which libraries to add?

[thiagokokada]

In this case you don't. The section that I linked in the README.md above explains that it is impossible for nix-alien to know which libraries it needs to add because you are in a Python script, not a binary (so it is basically the same case as dlopen explained in the README.md, where Python is probably calling ctypes or something).

You need to know which libraries to import in your program to make it work, and then use either -l or -p flags to add them.

If you have Steam installed or you don't mind it, you might want to check out steam-run, a FHS-compliant environment launcher that is built for running games. You can modify it in your system configurations if you need additional packages, too.
