隐式依赖关系来查找go stdlib软件包

Question

I have a stripped down environment, where I want to use go at a custom path.

printenv gives me:

GOOS=linux
GOROOT=/mygo
GOHOSTOS=linux
GOARCH=amd64
TMPDIR=/mytmp
GOHOSTARCH=amd64
GOPATH=/mysrcs
PWD=/home/andreas

Now if I try to compile go code, it fails to find the stdlib:

could not import fmt (cannot find package "fmt" in any of:
/mygo/src/fmt (from $GOROOT)

If I do find /mygo | grep fmt, I get:

/mygo/pkg/linux_amd64/fmt.a

When I use the system go (normal bash environment), it works fine. What implicit dependencies does go need to find the stdlib packages?

Answer 1

Thanks to @JimB, I managed to get it working.

I indeed want binary-only packaging of stdlib. Discussion online is that $GOROOT/pkg is a valid use-case for binary distribution, while $GOPATH/pkg might get deprecated soonish, so beware.

If you want to provide binary-only packages, https://github.com/tcnksm/go-binary-only-package shows how to create (annotated) src directory structure, in order for go to stop searching for source files.
