Build jsonnet with musl static binary

[vincent-herlemont]

Is there a way to build jsonnet with musl?

I am a novice in C++ development and I try to build jsonnet with musl in order to create a static binary (here the root issue anguslees/rust-jsonnet#40).

I updated the Dockerfile:L10 with adding CC="musl-gcc -static"

...
RUN cd jsonnet && \
    CC="musl-gcc -static" && make
...

The build pass ✔️ .

Is it enough to guarantee that jsonnet build with musl?

[sbarzowski]

Not 100% sure. Generally there should be no problem using Jsonnet with musl (we try not to depend on any glibc-specific stuff).

Try running ldd ./jsonnet to see if the result is a static binary.

[vincent-herlemont]

jsonnet seems no build as a static binary.

In the docker container, I ran ldd /usr/local/bin/jsonnet. See the output below.

	/lib/ld-musl-x86_64.so.1 (0x7f13ff919000)
	libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x7f13ff6a0000)
	libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x7f13ff686000)
	libc.musl-x86_64.so.1 => /lib/ld-musl-x86_64.so.1 (0x7f13ff919000)

Here the Dockerfile than I use

FROM alpine:latest AS builder

RUN apk -U add build-base

WORKDIR /opt

COPY . /opt/jsonnet

RUN cd jsonnet && \
    CC="musl-gcc -static" && make

FROM alpine:latest

RUN apk add --no-cache libstdc++ 

COPY --from=builder /opt/jsonnet/jsonnet /usr/local/bin
COPY --from=builder /opt/jsonnet/jsonnetfmt /usr/local/bin

CMD ["/bin/sh"]

How I can build jsonnet as a static binary?

[sbarzowski]

I think you should set the CXX environment variable in addition to CC. (Not sure if that is enough.)

[vincent-herlemont]

Yes, the behaviour is different.

Try with x86_64-alpine-linux-musl-g++ present alpine /usr/bin/.

Here others available musl packages

[vincent-herlemont]

I tried to set -fPIC.

    export CXX="x86_64-alpine-linux-musl-g++ -static" \
    export CC="x86_64-alpine-linux-musl-g++ -static" \

But the same error as this #908 (comment) happens.

One more thing to try: LDFLAGS=-static.

BTW if you want a static executable anyway, why not try https://github.com/google/go-jsonnet. It's static by default, faster and the version we're focusing our development efforts on.

[vincent-herlemont]

Test with LDFLAGS=-static. The same error is thrown.

I use jsonnet (c++) because I use rust-jsonnet and I want make my rust binary as static binary with musl. So I am stuck with this issue anguslees/rust-jsonnet#40. The following error happens when I try to build my rust binary with a musl target cargo build --target=x86_64-unknown-linux-musl.

It seems some symbole are missing hidden symbol '__dso_handle' isn't defined /usr/bin/ld: final link failed: Bad value. So I try to build jsonnet (c++) with musl to make sure that is possible before to dig in the rust binding.

So thank you for the information to https://github.com/google/go-jsonnet but I don't know if the binding go to rust will be easy :s.

Hmmmm...

This is about building the shared library. You probably don't need that if you want to have static binary in the end anyway.

Also, if you're using rust, perhaps https://github.com/CertainLach/jrsonnet will be interesting to you (that's a third-party unofficial implementation, though).

Re go-rust bindings: we offer a compatible C interface. It's a drop-in replacement when using a shared library. Not sure how to create a single shared binary with Go and Rust. Also it means your binary will include the Go runtime with GC, threads etc.
