wchar.go:44:8: error: enumerator value for '__cgo_enum__0' is not an integer constant about hid HOT 7 CLOSED

Could you try with updating to Go 1.8.1? These error messages seem originate from Go's compiler, not this library golang/go#14669

from hid.

I've tried go1.8 compiler (the latest available on NixOS so far). Errors are still here, but the text is a bit different. As far as I understand the golang/go#14669, one could workaround errors by passing '-O0'. I'll try to do that.

Another NixOS user here - I also ran into this and have been attempting to debug it. It seems to be indeed unrelated to geth and a general problem with the go compiler under NixOS. I have filed a separate issue here: NixOS/nixpkgs#25599 .

Thanks to @javaGH, looks like we used gcc instead of clang. So it is really a NixOS issue. Closing this one now.

Indeed, the issue was that under NixOS the Go compiler is built using clang, but then while trying to build geth the C compiler was set to gcc. I have an updated NixOS package for geth 1.6.1 over here which works for me: https://github.com/javgh/nixpkgs/blob/master/pkgs/applications/altcoins/go-ethereum.nix . Cheers!

I just wanted to pop in to say I'm seeing this too (via Nix) and this was a hard issue to track down.

Just as a FYI: The original guess regarding the compiler mixup was actually incorrect. Everything is built using gcc by default on Nix - including the Go compiler. Switching to clang still helps though as a workaround. The root cause is still unsolved though, as far as I know. This is the most recent issue about it: NixOS/nixpkgs#25959 .
