Undefined errors from CockroachDB when trying to build

[dalanmiller]

I've definitely ran make in the $GOPATH/src/github.com/cockroachdb/cockroach dir, but still seem to be getting this undefined errors.

See the last line of the readme:

Requires having the master branch of https://github.com/cockroachdb/cockroach checked out at $GOPATH/src/github.com/cockroachdb/cockroach, and running make in that directory.

Apologies @mjibson, as a post-posting edit, I mentioned that I had done that! 🙇

[madelynnblue]

Those identifiers should appear in a file called tokens.go. I'm not convinced make ran successfully because it would exist otherwise. Other option is to checkout https://github.com/cockroachdb/cockroach-gen at github.com/cockroachdb/cockroach which already has all of the files pregenerated.

That was it! I was getting really variable output when running make and assumed nothing went wrong. Blew everything away and then properly ensured I had cmake installed made everything go away.

Now I'm getting different undefined errors in a couple files when attempting to target WASM:

$ GOOS=js GOARCH=wasm go build -o main.wasm

../../cockroachdb/cockroach/pkg/util/sysutil/sysutil.go:51:23: undefined: syscall.SIGHUP

Ah yeah. WASM isn't going to work because cockroach uses some unix-only stuff that's only been added for windows. I think I fixed all of them once and the output was still like a 50MB wasm file which is way too huge for any browser or serverless platform to accept.
