Open Cubic Player Nix-file attempt (newbie needs help, this nix-file is stuck on libancient)

README.md

Due to lack of nix-skills I gave up on compiling it via nix (and ideally submitting it upstream). For now, I'm just using the AWESOME ocp player via this ~/bin/ocp shellscript:

#!/bin/bash
nix_windows(){
  test -d ~/apps/ocp || {
    mkdir ~/apps/ocp
    cd ~/apps/ocp
    wget "https://github.com/mywave82/opencubicplayer/releases/download/v0.2.107/ocp-windows-32bit-0.2.107.zip"
    unzip ocp-windows*.zip
    rm *.zip
  }
  cd ~/apps/ocp
  nix-shell -p wine --run "wine ocp.exe $*"
}

linux(){
  exec /usr/bin/ocp -fl0,r0 -va300 -dcurses "$*"
  #exec /usr/bin/ocp -fl0,r0 -va300 -dsdl2 "$*"
}

test -n $NIX_PATH && nix_windows "$*"
test -n $NIX_PATH || linux "$*"
