Static link libstdc++

[aslafy-z]

I'd like to ask pkg to statically link libstdc++ into the binary file. I currently need to add libstdc++ into my alpine container before running my binary file and I would like not having to.

FROM alpine:3.8
RUN apk add --no-cache libstdc++
COPY ./bin /bin
ENTRYPOINT ["/bin"]

Any thoughts?
Is this possible?

I'd love to know this too!

I presume this is the reason I'm getting the following error, when trying to run my binary in a scratch dockerfile:

Script
pkg --debug --targets node10-linux-x64 --output runme index.js

Dockerfile

FROM scratch
COPY runme /
CMD ["/runme"]

Error

standard_init_linux.go:211: exec user process caused "no such file or directory"

@igorklopov - first of all, thanks for an awesome tool!

Just reading your comments here...

Right. Try running args.push('--fully-static') here https://github.com/zeit/pkg-fetch/blob/master/lib/build.js#L72 and then passing -b option to your pkg call.

Is there any chance we can have this added to the pkg library (maybe as a CLI option)?

(I'd do it myself, but not sure if there's a reason it hasn't already been added.)

Hey wonderful team of pkg 😉 thanks for this awesome tool!

We're also interested in this issue at Clever Cloud for our CLI and we're available to test any alpha/beta if needed.

That would increase the binary size unnecessarily for majority of users, as it is simply improbable for a functional system to NOT have the standard C++ library. Additionally, static linking has certain security implications, and some distributions (such as EL) simply don’t provide static libraries (*.a).

Instead, make it Alpine only.

Instead, make it Alpine only.

Yeah I think they means to add this just for alpine binaries, btw I think that add an apk install command isn't that hard to do... Maybe we could add some docs about this
