Same issue in WebviewKo

OS: macOS 14.3.1 23D60 arm64 Kernel: 23.3.0 JVM: azul-1.8.0_392

To rule JNA reasons, I tried to write a JNI demo, but no miracle happens.

JNIEXPORT void JNICALL Java_top_ntutn_WebViewJNI_launchAndWait(JNIEnv *env, jobject obj, jstring url) {
    std::cout << "Well begin" << std::endl;
    webview::webview w(true, nullptr);
    std::cout << "Generated" << std::endl;
    w.set_title("Basic Example");
    w.set_size(480, 320, WEBVIEW_HINT_NONE);
    w.set_html("Thanks for using webview!");
    std::cout << "Half done" << std::endl;
    w.run();
}

I tried to add some log to find the position it stucks at:

And here is the log:

/Users/bytedance/IdeaProjects/webview-kt-wrapper/src/main/resources
Hello World from CPP
Well begin
Reach 2
Reach 4
Reach 5

I can do nothing more with my poor native development knowledge now.

You need to start Java with the option -XstartOnFirstThread. See the README for more info.

It works now, thank you. Apologize for my carelessness.

No problem! Just keep in mind that the thread that your main() starts with will need to be the same thread you use when you run() the webview.
