C# .NET core Avalonia 11.0版本,发布linux和MAC的简单记录

.net core 7.0+centos 7.0

cetnos目前运行在hyper V虚拟机里

虚拟机部署的注意事项

1 需要配置网络环境,

确保在同一局域网下

如果sftp无法连接

ctrl+shift+f2切换到命令行,开启22端口

iptables -I INPUT -p  tcp --dport 22 -j ACCEPT

　

同时虚拟机网络也要正确配置.

发布流程如下

1 发布项目,选择目标运行时为linux-X64,部署模式为独立,这样就不需要安装.net core运行环境,此处可根据实际情况自行调整下

如图设置即可

2

发布后,使用Xftp上传

以上传到/usr/local/bin/Test2 目录下为例

3

右击目标运行文件,通常为项目名,没有后缀名

选择可执行

4

打开kconsole,cd切换到目标路径

执行 ./AvaloniaTest ,此处AvaloniaTest 为目标文件名

4

项目正常运行

常见问题:

1 default font familyname can't be null

提示缺少默认字体,需要指定字体

参考github上的链接,设置默认字体后依然报错

https://github.com/AvaloniaUI/Avalonia/issues/4427

using Avalonia;
using Avalonia.Media;
using Avalonia.ReactiveUI;
using System;

namespace ExampleApp
{
    internal class Program
    {
        [STAThread]
        public static void Main(string[] args) => BuildAvaloniaApp()
                .StartWithClassicDesktopLifetime(args);

        public static AppBuilder BuildAvaloniaApp()
        {
            FontManagerOptions options = new();
            if (OperatingSystem.IsLinux())
            {
                options.DefaultFamilyName = "<Linux Default Font Family Name Here>";
            }
            else if (OperatingSystem.IsMacOS())
            {
                options.DefaultFamilyName = "<macOS Default Font Family Name Here>";
            }
            // No need to set default for Windows
            return AppBuilder.Configure<App>()
                        .UsePlatformDetect()
                        .LogToTrace()
                        .UseReactiveUI()
                        .With(options);
        }
    }
}

　　

  FontFamily = new FontFamily("avares://AvaloniaTest/Assets/Fonts/微软雅黑.ttf#Microsoft YaHei")

　　

不行,报错为

could not create glyphtypeface

如果报这个错误,参考问题2

 2 could not create glyphtypeface

拷贝windows系统自带的微软雅黑到如下路径

/usr/share/fonts/chinese/msyh.ttc

　运行fc-cache -f -v 命令,更新字体缓存

fc-cache -f -v

　　修改Program.cs

 public static AppBuilder BuildAvaloniaApp()
    {
FontManagerOptions options = new();
  options.DefaultFamilyName = "Microsoft YaHei";
        return AppBuilder.Configure<App>()
            .UsePlatformDetect()
            .WithInterFont()
            .LogToTrace()
            .UseReactiveUI().With(options);

    }

　　重新发布,即可.

mac版本

测试环境:

avalonia+cefnet 跨平台浏览器套壳demo

demo为双浏览器界面

M2 arm 处理的mac系统

虚拟机,都运行通过.

直接编译后拷贝到任意位置

就可以直接运行了

demo为调用cefnet核心的avalonia项目

问题:

把编译后的.app文件,打包成zip后拷贝到mac,再解压缩,会无法运行,原因不明.

解决方法,mac打包成dmg文件,再分发.

没有签名也可以分发.就是会多一次提示.

打包命令

hdiutil create -srcfolder [源文件夹路径] [目标DMG文件路径]

　　

附mac打包脚本,以cefnet为例
