不能使用从代号一创建 CEF 浏览器

时间：2021-05-03 17:19:58

标签： java linux codenameone archlinux

每次我尝试在代号为 1 中调用它时，我的应用程序都无法运行 BrowserComponent。它给我一个创建 CEF 浏览器失败的错误。旁边的一切都运行得很好。我按照此链接中的说明卸载并安装了 CEF Codename One CEF Support 我试图解决我的问题，因为我在上一个链接的已知问题中找到了它

我按照指示进行操作并尝试修复LD_LIBRARY_PATH

这是我这样做后终端的输出：

[kagha@archbios ~]$ whereis java
java: /usr/bin/java /usr/share/java /usr/lib/jvm/java-8-jdk/bin/java
[kagha@archbios ~]$ echo $JAVA_HOME
/usr/lib/jvm/java-8-jdk
[kagha@archbios ~]$ echo  $LD_LIBRARY_PATH
/usr/lib/jvm/java-8-jdk/lib/amd64
[kagha@archbios ~]$ find /usr/lib/jvm/java-8-jdk/ | grep "libawt.so"
/usr/lib/jvm/java-8-jdk/jre/lib/amd64/libawt.so

但问题仍然存在 我使用 OS Arch Linux 内核版本 5.10.32-1-lts 和 Apache netbeans 12.1 作为 IDE

我试图运行的代码

Form hi = new Form("Browser", new BorderLayout());
BrowserComponent browser = new BrowserComponent();
browser.setURL("https://www.codenameone.com/");
hi.add(BorderLayout.CENTER, browser);*/

这是控制台中的完整错误：

如果需要，我将不胜感激并提供更多信息，提前致谢

答案 0 :(得分：0)

您应该使用新的 Maven support。这应该可以解决问题，因为 Maven 插件会自动将所需的条目添加到 LD_LIBRARY_PATH。

您可以从 https://start.codenameone.com 下载基本模板并将您的代码粘贴到那里。
