build errors on GOARCH=arm64 (type Cpu has no field or method Get) about gosigar HOT 6 CLOSED

We still have this problem. See: pingcap/tidb#39526 (comment)

This is a bit weird. This build runs fine on an AMD64 Linux machine (running go 1.18.2), but not on an AMD64 Darwin machine (running go 1.18.3).
I'm not very familiar with how go handles cross-compiling, and why it might decide to do that differently depending on the OS of the host compiler, but I'll see what I can learn on Friday.

In the meantime, if you have the time, energy, and interest required to figure out what's wrong, please do feel free to let us know what you discover.

For what it's worth, 7d5fe18 appears to be the commit that converted the repo to go mod style dependency management... and the ARM64 build failed to build on Darwin with the same error you are reporting here. So, this isn't a very new failure.

CGO_ENABLED=1 is needed to enable cgo when cross-compiling in Darwin. (There is some "C" code in sigar_darwin.go).

Ah. That's a confusing requirement, but it does make the build succeed on Darwin.

Is there anything that you would like us to do here, or can this Issue be closed?
