LWJGL missing EGL .dll

I hope someone here can help me with this. I just tried to add EGL to my game (for shared contexts), and it can't find the egl .dll file. Build.gradle:

val lwjglVersion = "3.3.3"
val jomlVersion = "1.10.7"

val lwjglNatives = ...

dependencies {
    api("org.joml:joml:1.10.5")

    implementation(platform("org.lwjgl:lwjgl-bom:$lwjglVersion"))

    implementation("org.lwjgl", "lwjgl")
    implementation("org.lwjgl", "lwjgl-egl")
    implementation("org.lwjgl", "lwjgl-glfw")
    implementation("org.lwjgl", "lwjgl-opengl")
    runtimeOnly("org.lwjgl", "lwjgl", classifier = lwjglNatives)
    runtimeOnly("org.lwjgl", "lwjgl-glfw", classifier = lwjglNatives)
    runtimeOnly("org.lwjgl", "lwjgl-opengl", classifier = lwjglNatives)
    implementation("org.joml", "joml", jomlVersion)

    api(project(":glwt"))
    api(project("builder"))
}

val lwjglVersion = "3.3.3"
val jomlVersion = "1.10.7"

val lwjglNatives = ...

dependencies {
    api("org.joml:joml:1.10.5")

    implementation(platform("org.lwjgl:lwjgl-bom:$lwjglVersion"))

    implementation("org.lwjgl", "lwjgl")
    implementation("org.lwjgl", "lwjgl-egl")
    implementation("org.lwjgl", "lwjgl-glfw")
    implementation("org.lwjgl", "lwjgl-opengl")
    runtimeOnly("org.lwjgl", "lwjgl", classifier = lwjglNatives)
    runtimeOnly("org.lwjgl", "lwjgl-glfw", classifier = lwjglNatives)
    runtimeOnly("org.lwjgl", "lwjgl-opengl", classifier = lwjglNatives)
    implementation("org.joml", "joml", jomlVersion)

    api(project(":glwt"))
    api(project("builder"))
}

If I try adding

runtimeOnly("org.lwjgl", "lwjgl-egl", classifier = lwjglNatives)

runtimeOnly("org.lwjgl", "lwjgl-egl", classifier = lwjglNatives)

gradle can't find it? Please help, been struggling with this for an hour.

Sorry

java.lang.UnsatisfiedLinkError: Failed to locate library: libEGL.dll

then lemme get the gradle one...

is the file there? I meant check if its in your local repository. It's probably not considering the error, but if it is delete it and reload your project*

The TyphothanianOP•2d ago

It isn't, and I checked where it's looking, and it doesn't exist. The same syntax works for the other things, but not egl I mean for the file and the website

nikcho-kouhai•2d ago

egl 3.2.3 worked for me on gradle. On maven the higher version works fine. I suppose you can try any of the versions above 3.2.3 and below 3.3.3 see which is the latest one that works for gradle actually 3.3.2 worked so I guess go with that one

The TyphothanianOP•2d ago

oh dang lemme check that

nikcho-kouhai•2d ago

actually 3.3.3 also works after specifying the version? implementation("org.lwjgl", "lwjgl-egl","3.3.3") no idea what gradle is doing

The TyphothanianOP•2d ago

Well the base egl stuff works, the natives don't

it turns out "it's not a bug, it's a feature" you are just gonna have to find natives-windows.jar and put it in your classpath

nikcho-kouhai•2d ago

https://www.lwjgl.org/customize you can use this as pointed out by the installation guide (https://github.com/LWJGL/lwjgl3-wiki/wiki/1.2.-Install) Just uncheck everything, then choose EGL and on the left side there is "natives". Choose whichever platform you want (in your case windows) and download it.

Tyvm I tried that. Downloaded build.gradle.kts with egl, including natives, and it wasn't there. Even downloaded the zip and it wasn't there. Tried 3.3.3 and 3.3.2.

hope they can help

nikcho-kouhai•2d ago

well it's in the zip bundle. It would be great if you can get it working with gradle assuming it's actually in the repositories and not done on purpose.

Really? My zips don't have egl natives, just lwjgl natives

nikcho-kouhai•18h ago

you are right. My bad. It's interesting, because egl.dll isn't even listed here: https://www.lwjgl.org/browse/stable/windows/x64 You might have to build it yourself or something.. I guess wait a response on the github issue
