Good idea.
FYI - this is on a Fedora 37 6.1.8-200.fc37.x86_64 server with go version
go1.20 linux/amd64.
I'm running a VM in Virtualbox with snapshots so it's very easy to go back
to an unmodified
system after running an experiment. Note that I'm adding the '-a' option to
the go build commands
If I read the 1.20 release notes correctly, there has been a change with
how the compiled std lib not only is delivered (not anymore) and cached, so
that it now ends up in the module cache. Maybe you can retry your
experiments with 1.20 if this now works without the slightly ugly
workarounds?
I agree with you 100%. The 'go install' step that creates the shared
runtime library should only be done by
root.
On the other hand, there's no reason I can see for the 'go build' step to
write anything at all
into /usr/local/go. But that's clearly happening. That's one of the causes
of this
> So, the solution to problem #1 is to make sure a normal user can create
/usr/local/go/pkg/linux_amd64_dynlink and files in and underneath it.
While this is fine as a proof of concept and to diagnose the situation, I
don't think that it can be called good advice to make /usr/local writeable
to
Thanks for the comments. I had to do it as root because running
go install -buildmode=shared std
as me results in
go install internal/goarch: mkdir /usr/local/go/pkg/linux_amd64_dynlink:
permission denied
As root, changing the ownership of /usr/local/go/pkg/linux_amd64_dynlink to
me, and
Looking back at your posts, I think you got there because your initial
build of the shared library was via sudo? I don’t think that was correct
and you didn’t need sudo.
If the shared library only contained code needed for your executable, then
it could only be shared by other instances of your
I'm the original poster. I've looked into this more and I might have an
explanation for
what's going on.
Just for yuks, I started with perhaps the simplest Go program, which I
called t.go:
package main
func main() {
}
As root, I was able to build both a dynamically (21512 bytes) and a
