Unable to dynamically load glass GTK library

bigdale123 · February 4, 2025, 11:10pm

Hi, first off i’d like to say I might have bitten off more than I can chew with this. I am trying to package a program called sdr-trunk, which is a JavaFX application. So far my current package definition “works”, autopatchelf does patch the binaries and the application will start. However, when it tries to load the glass GTK library the application won’t load the GUI. It does not crash, it just fails to start the GUI.

I have gotten lost and don’t know where to go from here; I have tried using makeWrapper to set LD_LIBRARY_PATH, and made edits to the script that launches the java binary using substituteInPlace. Neither have fixed the issue, although the later change seems correct to me (unless i learn otherwise ). I would appreciate any guidance on a fix, it’s my first time trying to package anything. I will include the app log and nix file below.

The nix file (sdrtrunk.nix):

{ stdenv, lib, fetchzip, autoPatchelfHook, jdk23, glib, gtk3, xorg, ffmpeg_6-full, sdrplay, glibc}:
let
    version = "0.6.1";
in
stdenv.mkDerivation {
    pname = "sdrtrunk";
    version = version;
    #Yeah, the source code exists, I can't hack it. I can't figure out how to package a gradle build in nix.
    src = fetchzip {
        url = "https://github.com/DSheirer/sdrtrunk/releases/download/v${version}/sdr-trunk-linux-x86_64-v${version}.zip";
        hash = "sha256-iMnR8d7fnnpcBAKoPn8zyuTWzcklqy4oyAKsTHljOPc=";
    };

    nativeBuildInputs = [
        (jdk23.override { enableJavaFX = true; })
        autoPatchelfHook
        glib
        gtk3
        xorg.libXxf86vm
        xorg.libX11
        ffmpeg_6-full
        sdrplay
        glibc
    ];

    preBuild = ''
        addAutoPatchelfSearchPath ${jdk23}
        addAutoPatchelfSearchPath ${gtk3}
        addAutoPatchelfSearchPath ${glib}
    '';

    autoPatchelfIgnoreMissingDeps = [ "libavcodec.so.5*" "libavformat.so.5*" "libavcodec-ffmpeg.so.5*" "libavformat-ffmpeg.so.5*"];

    installPhase = ''
        runHook preInstall
        mkdir -p $out
        cp -r * $out
        rm $out/bin/sdr-trunk.bat

        # point shell script to correct lib folder
        substituteInPlace $out/bin/sdr-trunk \
            --replace 'APP_HOME="`pwd -P`"' 'APP_HOME="'$out'"'
        
        runHook postInstall
    '';

    meta = with lib; {
        description = "A cross-platform java application for decoding, monitoring, recording and streaming trunked mobile and related radio protocols using Software Defined Radios (SDR).";
        homepage = "https://github.com/DSheirer/sdrtrunk";
        license = licenses.gpl3Only;
        platforms = platforms.unix;
        maintainers = with maintainers; [bigdale123];
        mainProgram = "sdrtrunk";
    };
}

And the application log:

Have you tried using a JRE from Nixpkgs to run the JAR instead of using the shipped shell script launcher? That’s generally been more successful for me when doing this sort of thing.

You can find out how to build Gradle packages here: Nixpkgs Reference Manual

As a practice I just took some time to package this myself. Maybe this should be upstreamed into Nixpkgs if it’s popular.

Wow, I can’t believe I missed the section in the manual about Gradle . If you wanted to upstream it to nixpkgs, I wouldn’t say no. But even if you do, I think im going to keep trying to package it myself for my own edification. Thanks for the help!

(Edit) I tried your flake out, since it is also the first time I have played with flakes. It works great! I hope in the future I can package something that fast.
