Does creating custom OPA image with some plugins makes WASM unavailable?

[dushyant7917]

We use a custom version of OPA, compiled by us making use of the plugin feature. But it doesn't have WASM support although the default image has WASM support available.

Output for custom image ./opa version

You'll need to pass the same flags as are passed in the upstream build. Notably, -tags opa_wasm for go build. Also make sure that CGo is available.

bytecodealliance/wasmtime-go#54 Sounds like this one? Perhaps you could have a look at that? 🔍

Thanks, looks the same issue. Will try it out.

I tried using gcc 7+ but still getting same error.
Docker file of image getting used to build the code contains below commands.

RUN yum -y group install 'Development Tools' && \
    yum -y install python-setuptools glibc-static && \
    add_strata_repo.py --name devtoolset-7 --type rpm-release-candidate && \
    yum -y install devtoolset-7 && \
    yum clean all
RUN scl enable devtoolset-7 bash

What do you suggest now?

[srenatus]

Ask in the linked wasmtime-go issue, maybe? Since it seems so related. I'm afraid I have no idea what's packaged and available in the linux distribution you're using. You also haven't mentioned which one that is, have you? 🤔

Using centos7.
