Overview

You are running Nix/NixOS and have ever encountered the following problem?

> ./factorio
bash: ./factorio: No such file or directory

Fear not, now there is nix-autobahn which will help you running those binaries:

> nix-autobahn factorio
Pick provider for libX11.so.6: xlibs.libX11.out /lib/libX11.so.6
Pick provider for libXinerama.so.1: xlibs.libXinerama.out /lib/libXinerama.so.1
Pick provider for libpulse-simple.so.0: pulseaudioFull.out /lib/libpulse-simple.so.0

nix-autobahn looks through the output of ldd factorio for missing shared objects (*.so* files). For each missing one nix-index's nix-locate is used to determine provider candidates (read: packages that offer this shared object). If more than one candidate is found a nice™^™ TUI asks you to pick one. All of the chosen packages are baked into a FHS-compatible Sandbox that can be built through a nix expression inside of a shell script.

All that is left from now is to run it:

> ./run-with-nix
# ...
   0.010 Error SDLWindow.cpp:186: Failed to create an application window. SDL_Error: Failed loading libGL.so.1: libGL.so.1: cannot open shared object file: No such file or directory
   0.010 Error Util.cpp:83: Failed to create an application window. SDL_Error: Failed loading libGL.so.1: libGL.so.1: cannot open shared object file: No such file or directory
   1.316 Goodbye

Sadly, that didn't work so well. Fortunately we know why: We need a provider for libGL.so.1. Now we have two options: Either we pass -l libGL.so.1 to nix-autobahn to tell it to find a provider for that given shared object or we just know the missing package is libGL. In the latter case we can pass -p libGL to nix-autobahn to ensure that a provider for libGL ends up in the build expression:

> nix-autobahn factorio -p libGL
Pick provider for libX11.so.6: xlibs.libX11.out /lib/libX11.so.6
Pick provider for libXinerama.so.1: xlibs.libXinerama.out /lib/libXinerama.so.1
Pick provider for libpulse-simple.so.0: pulseaudioFull.out /lib/libpulse-simple.so.0
> ./run-with-nix

And we are good to go!

Usage

USAGE:
    nix-autobahn [OPTIONS] <BINARY>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -l, --additional-libs <libs>...        Additional libraries to search for and propagate
    -p, --additional-pkgs <packages>...    Additional packages to propagate

ARGS:
    <BINARY>    dynamically linked binary to be examined

Dependencies

• nix-index. Ensure that both nix-index is installed and has a valid index. To rebuild the index simply run nix-index. For further information refer to nix-index's manual: nix-index --help. Rebuilding the index is not frequently needed, in fact we recommend doing so if you ran into problems or changed your channel (e.g. nixos-19.03 -> nixos-19.09).
