Hi. You’ve given me no information about how I can help you solve your problem.

Which version of Go? Which operating system? What commands did you type, show all of them, what happened when you typed them, show as much as you can.

This is seen when cross building for Solaris, or when building on Windows. I'll be following up with some fixes.

thanks

I get these issues when building with GOOS=openbsd using go version go1.15.5 linux/amd64 on Arch Linux:

# github.com/pkg/term/termios
vendor/github.com/pkg/term/termios/pty.go:22:14: undefined: open_pty_master
vendor/github.com/pkg/term/termios/pty.go:27:16: undefined: Ptsname
vendor/github.com/pkg/term/termios/pty.go:32:8: undefined: grantpt
vendor/github.com/pkg/term/termios/pty.go:37:8: undefined: unlockpt

The results are the same for:

• Latest master, d02e49dd31404f3c3cf4b5469b28942194e0ca23
• An earlier commit that works with FreeBSD, but not with OpenBSD: c3ffed290a03

I tried to add some CI around this and from what I can tell, because the openbsd bindings use CGO it is difficult to cross compile them. I think this is the same problem that solaris faces.

Experienced the same issue now. I transpiled a C file with c4go, which uses your package. Using Windows 10 (20H2) AMD64, Go 1.15.2, building with Goland 2020.3.

Attaching the go-file I'm trying to run. main.zip

[davecheney]

Thanks for the detail. I don’t know how to fix this as cross compiling cgo code is fraught with difficulty

Sorry I never followed up -- I think at some point I assumed @davecheney wasn't interested in contributions to this package, as of the two PRs I submitted to it, one took over a year to get merged (with no feedback in the interim) and the other is still outstanding (though it now had conflicts). I can try to resurrect my work (I wound up going a totally different to not depend on this package) if there is interest, but I don't want to invest the time to put together a fix if its just going to bitrot indefinitely.

@gdamore i sent you an invite to this repo so I won’t be a blocker any more
