I will explain this later if needed as I need to leave, but long story short, this should work with zsh as well (it is compiling right now so I had no time yet to test the binary output):

# You can also create a mkShell by basically copying all fields of bespokesynth,
# but it is easier to reuse stuff
default = pkgs.bespokesynth.overrideAttrs (finalAttrs: previousAttrs: {
# Bespokesynth should use this instead of patching LD_…
NIX_LDFLAGS = "-rpath ${pkgs.lib.makeLibraryPath (with pkgs; with xorg; [ libX11 libXrandr libXinerama libXext libXcursor libXScrnSaver ])}";
dontPatchELF = true; # needed or nix will try to optimize the binary by removing "useless" rpath
# We add some more packages here to quickly build the package
buildInputs = previousAttrs.buildInputs ++ scripts;
});
});
};
}
To use:
$ nix develop -c zsh
$ cd BespokeSynth # make sure to clone it with submodules
$ configure
$ cd build
$ build
This is mostly a proof of concept, but I think we should add this kind of package to nixpkgs to ease development as right now the user experience is really bad.
Proof:
