go.mod not found

[shrimalmadhur]

Hello I am running into this weird issue where it says go.mod not found, even though there's a go.mod in that folder

go: go.mod file not found in current directory or any parent directory; see 'go help modules'
ERROR: Failed to cross compile package: exit status 1.

I am using xgo -go 1.16 --targets="darwin/*,windows/*,linux/*" -out "rosetta-cli-0.7.0" .
Just to add more clarity, It does work when I do xgo -go 1.16 --targets="darwin/*,windows/*,linux/*" -out "rosetta-cli-0.7.0" github.com/coinbase/rosetta-cli but it doesn't work when I do that in current directory

Interestingly I was not getting this when I was using https://github.com/karalabe/xgo

I'm still having this issue, when using this in a local repostory, I'm not sure if this scenario is supported:

Example:

git clone git@github.com:banzaicloud/bank-vaults.git
cd bank-vaults
xgo --targets=darwin/arm64 ./cmd/bank-vaults

Output:

@bonifaido is it because you are providing ./cmd/bank-vaults in there? You don't have go.mod in that folder. You just need to do that in current dir by providing .. That should work I guess.

[bonifaido]

There is a CLI built from this directory (it has a main() method) and I would like to build that, the root (.) doesn't hold any compilable sources on that level. This is a common idiom in Go AFAIK to have the CLIs built from ./cmd/... according to: https://github.com/golang-standards/project-layout

[shrimalmadhur]

I see. but xgo expects a go.mod from the directory where you are building. Not sure how to work around for your case.

[bonifaido]

This worked in karalabe/xgo.

[shrimalmadhur]

I see. in that case, I would defer this to the @crazy-max for this. I have not looked into the differences between these 2 repos. :)

@bonifaido using -pkg might solve your problem. Here is how I am using it for a similar situation https://github.com/dnote/dnote/blob/master/scripts/cli/build.sh#L80-L89
