Compile Error

I ran into these errors on go 1.15.9 linux/amd64 while testing cross-compiling.

# github.com/anatol/luks.go
_build-booster-xbps/src/github.com/anatol/luks.go/dm.go:32:3: cannot use int(volume.storageOffset) (type int) as type uint64 in field value

How do you cross compile? What GOOS and GOARCH?

[travankor]

linux/arm64 is what I tested with using the standard compiler (not gcc-go).

The error message says dm.go wants to use newer API than it recorded in go.mod. You do not use pinned version of devicemapper.go, do you?

Golang has a great modules system. It allows to pin versions of dependent packages by recording it into go.mod. And not using this feature is looking for troubles (like the one above).

I updated luks.go to the API changes in devicemapper.go for now. But i would suggest to use go modules functionality to track dependencies versions.

-mod defaults to vendor if there's a vendor directory, otherwise uses default for go.

But this project does not have vendor so it comes from somewhere else. So the question - is this vendor directory synchronized with go.mod?
