为 linux-musl-arm 编译 dotnet core 应用程序

Lud*_*ltz 6 c# arm openwrt musl .net-core

我尝试使用以下命令在ARM Cortex A7上为OpenWRT编译一个简单的.NET Core hello world 应用程序：linux-musl-arm

dotnet publish --configuration Release --runtime linux-musl-arm --self-contained

我遵循了本教程：https://davidjmclaughlin.com/projects/how-to/2020/03/15/running-.net-core-on-openwrt-and-raspberry-pi-4.html并安装了所有必需的库但没有成功。

我正在尝试在 Teltonika 的 RUTX11 上运行此代码

我不知道我错过了什么......

好的，感谢@albirew的回答，看起来 musl 版本不匹配...我尝试将.NET Core版本降级到使用musl和x86 libc库的版本( netcoreapp3.1)，但现在应用程序尝试加载ld-linux-armhf.so，但它不存在在系统中，而是有（这是随.NET Coreld-musl-armf.so的下一版本加载的）

linux-arm注意：当我使用运行时（而不是linux-musl-arm）编译时，这是同样的错误

就像我说的，这是构建的运行时与运行的运行时之间的版本不匹配。

hnyman在openwrt 论坛上解释说，看到__time64: symbol not found错误让他相信您正在使用带有 x64 时间符号的 musl 1.2.2+ 构建应用程序，但 Teltonika 路由器正在使用 OpenWrt 21.02.x 以及旧版 musl 1.1.24 版本和 x86 时间处理。
