KMP Desktop add the natives for your platform(s).

[haffadan]

Hi!
I have implemented version 0.11.1 in my Android Studio KMP project (Android and Desktop at the moment) everything went ok to remove all imports and re import them with the org.maplibre.*
The Desktop was working with KcefProvider, but now I get a error like:
"Native library not found in JAR: /windows/amd64/opengl/maplibre-jni.dll"
I have the lib folder with the content, but I have no clue where to start searching or fixing this problem.

Have you added this block to your dependencies?

      runtimeOnly("org.maplibre.compose:maplibre-native-bindings-jni:0.11.1") {
        capabilities {
          requireCapability("org.maplibre.compose:maplibre-native-bindings-jni-windows-amd64-opengl")
        }
      }

Hi!
Thanks for a rapid answer, I had copy/paste the block from your demo code, and used it in wrong place, in my code it looks like below.

Now my dependencies look like :

    desktopMain.dependencies {
        implementation(compose.desktop.currentOs)
        implementation(libs.kotlinx.coroutinesSwing)
        implementation(libs.ktor.client.okhttp)
        implementation(libs.maplibre.compose)
        runtimeOnly("org.maplibre.compose:maplibre-native-bindings-jni:0.11.1") {
            capabilities {
                requireCapability("org.maplibre.compose:maplibre-native-bindings-jni-windows-amd64-opengl")
            }
        }
    }

And it sync OK, but when running it in Console app starting, but when I get to map screen it crash with error:

• What went wrong:
  Execution failed for task ':composeApp:run'.

Process 'command 'C:\Program Files\Java\jdk-22\bin\java.exe'' finished with non-zero exit value 1

Not much of information for me to know what goes wrong.

Tried to get more info with
./gradlew :composeApp:run --stacktrace
and
./gradlew :composeApp:run --debug
but couldnt find any more specific info.

Could you share the full log from those attempts, and details of the hardware and Windows version you're running on, and perhaps a sample project reproducing the issue?

Did get little more info when running
./gradlew :composeApp:run --info

adding log file.

The crash happened outside the Java.txt

Ah, so essentially a segfault while loading the library, interesting. Relevant bits of the log:

I'm unable to repro this on my Windows machine.

Could you share more information in #611?

Particularly useful would be:

• A minimal project that reproduces the issue.
• MSVC version (search Apps and Programs for "Microsoft Visual C++ Redistributable" or similar things
