为 linux-musl-arm 编译 dotnet 核心应用程序
Compiling dotnet core app for linux-musl-arm
我尝试为 OpenWRT 编译一个简单的 .NET Core hello world 应用程序 ARM Cortex A7 使用 linux-musl-arm 和以下命令：
dotnet publish --configuration Release --runtime linux-musl-arm --self-contained
但是当我尝试执行它时出现以下错误:

好的，感谢 @albirew 的回答，看起来 musl 版本不匹配...我试图降级 .NET Core 版本到使用 musl 和 x86 libc 库 (netcoreapp3.1) 的版本，但现在应用程序尝试加载 ld-linux-armhf.so 但是它在系统中不存在，而是有ld-musl-armf.so（这是加载.NET Core的下一个版本）
注意：当我用linux-arm运行time（而不是linux-musl-arm）
编译时也是同样的错误
关于OpenWrt版本的更多信息21.02.0:
就像我说的，这是 运行times 构建与 运行 构建之间的版本不匹配。
hnyman 在 openwrt forums 上解释说，看到 __time64: symbol not found 错误让他相信你正在使用 musl 1.2.2+ 和 x64 时间构建你的应用程序符号，但 Teltonika 路由器使用的是 OpenWrt 21。02.x 具有较旧的 musl 1.1.24 版本和 x86 时间处理。
