Do you know if ILCompiler is implemented for riscv64? If it is, then the runtime build system should be taught to build it by default (that may or may not involve Subsets.props). Otherwise we should teach sdk repo to stop requiring it for riscv64. I think the error message is saying that the package can't be found locally. In |

Slightly off-topic, can you help me set up a debian:sid (or any other) container that supports cross-compilation from x86_64/amd64 to riscv64? The obvious thing (at least to me) doesn't work: ROM debian:unstable

@omajid At Samsung, we use Ubuntu for cross-compilation. I know it's not Debian, but configuration should be similar.

This seems very similar to dotnet/sdk#40843 (comment). Essentially, runtime built a version of crossgen with a different package name than aspnetcore expects. This might be a question for someone on the aspnetcore or runtime team. |
