[question/bug] Problem building for riscv64gc. Are there plans to support it?

[johnnyasantoss]

Hello,

I'm trying to cross compile floresta @ 362c0ea to a riscv64gc target and I keep getting this error:

it seems like this architecture isn't well-supported yet.
Are there any plans to support it? Is this fixable? or should I open another issue on the other repo to try avoiding having this dep?
Is riscv64 an arch that you have plans to support?

[briansmith]

ring-0.16.20

riscv64gc is supported in the latest ring 0.17.X versions and not in 0.16.x.
