Using with go mod

[kolaente]

Is it possible to use xgo with go modules? When using the latest version of xgo, it doesn't use the modules, I get an error like

go get: warning: modules disabled by GO111MODULE=auto in GOPATH/src;
	ignoring go.mod;
	see 'go help modules'

IMHO there are two possibilites to solve this: Either add an option to xgo which allows specifying extra evironment variables which are then passed to the container or an extra parameter to enable go modules (which would also pass an environment variable to the container).

I don't think any extra options to xgo are needed. xgo can determine whether the package to be built is inside GOPATH or not and reproduce that setup in the container.

Is that currently working? So, if I mount it to somewhere outside of GOPATH, will xgo automatically use go modules? (Or is that a proposal) It could also look for a go.mod file and use go mod if it finds one.

It's not currently working, it's a proposal.

Need add Build flags "-mod=vendor"

[kolaente]

@zaaksam Do you think it should also try to autodetect that and build accordingly? (aka look for a vendor folder and go.mod and the use the vendor folder) Or only use an extra flag to explicitly enable it?

I've hacked a pr together: #144

The PR I sent to @kolaente (
kolaente#1) finishes the work he started. It autodetects the use of Go modules, and from there, uses go.mod to drive the rest of the build process. It also detects if a vendor directory is present, and if it is, passes -mod=vendor to go build. As a bonus, this also enables scenarios like #115 and #108.

@zgramana so does this actually work now? (I was wondering because the PR seems to be merged while this issue is still open) 🤔

This was merged into @kolaente’s fork. Given that they are actively maintaining theirs, I recommend you use theirs instead: https://github.com/techknowlogick/xgo.
