我尝试编译简单 .net core Hello World App for OpenWrt on ARM Cortex a7 使用 linux -musl-arm 带有以下命令：
dotnet publish --configuration Release --runtime linux-musl-arm --self-contained
但是当我尝试执行它时，我会遇到以下错误：

编辑2：
好的，感谢 @albirew 回答它看起来像Musl版本不匹配...我试图将 .net Core 版本降级到使用 musl的版本带有 x86 libc libraries（ netCoreApp3.1 ），但现在该应用程序尝试加载 ld-linux-armhf.o 系统中不存在，而是 ld-musl-armf.so （已加载了下一个版本的 .net core ）
注意：当我使用 linux-arm 运行时（而不是 linux-musl-arm ）编译时，这是相同的

I don't know what i'm missing...
EDIT 2:
Ok thanks to @albirew answer it look like the musl version mismatch... I tried to downgrade the .NET Core version to a version that use musl with x86 libc libraries (netcoreapp3.1) but now the app try to load ld-linux-armhf.so but it doesn't exist in the system, instead there is ld-musl-armf.so (this was loaded with next version version of .NET Core)
Note: it's the same error when i compile with linux-arm runtime (instead of linux-musl-arm)

就像我说的那样，这是反对vs vs vs vs vs vs vs vs的版本不匹配的版本。
hnyman 在 OpenWrt论坛< /a>看到
__ time64：找不到符号错误使他相信您正在使用MUSL 1.2.2+使用X64 Time符号构建应用程序，但是Teltonika路由器正在使用OpenWrt 21.02.x，较旧的Musl 1.1.24版本和X86时间处理。Like I said, this is a version mismatch between the runtimes build against vs run against.
hnyman explained it on openwrt forums that seeing the
__time64: symbol not founderror made him believe you are building your app using musl 1.2.2+ with x64 time symbols, but the Teltonika router is using OpenWrt 21.02.x with the older musl 1.1.24 version and x86 time handling.
