Difficulty building under Alpine 3.19

[strophy]

I'm trying to build the grpc-web protoc plugin under Alpine as a part of this project using the following Dockerfile:

FROM alpine:3.19 as grpc_web
RUN apk add --no-cache \
        build-base \
        curl \
        protobuf-dev
RUN mkdir -p /grpc-web
RUN curl -sSL https://api.github.com/repos/grpc/grpc-web/tarball/1.5.0 | tar xz --strip 1 -C /grpc-web
WORKDIR /grpc-web
RUN make -j$(nproc) install-plugin

This results in an enormous error from the Abseil dependency, starting out like this:

 > [grpc_web 6/6] RUN make -j$(nproc) install-plugin:

Adding ARG CPPFLAGS=-std=c++17 resolves the Abseil errors but instead returns the following error:

I don't think these errors are related to musl libc, is there a problem in the protobuf-dev package, or what am I missing here?

I think I tracked the problem down to the Alpine protobuf-dev package not containing the *.a files required for the static linking used by grpc-web during its build process, they're probably trying to encourage dynamic linking. I ran into a lot of trouble trying to match up protobuf and abseil versions building my own dependencies for a while, but then found the easiest way is to build and install the dependencies linked in the third party submodules directory instead. Build is now working again using the following steps:

FROM alpine:${ALPINE_IMAGE_VERSION} as grpc_web
RUN apk add --no-cache \
        autoconf \ 
        automake \
        build-base \
        git \
        libtool
ARG GRPC_WEB_VERSION
RUN git clone --recurse-submodules --branch=$GRPC_WEB_VERSION https://github.com/grpc/grpc-web.git
WORKDIR /grpc-web/third_party/protobuf
RUN ./autogen.sh && \
    ./configure && \
    make -j$(nproc) && \
    make install
WORKDIR /grpc-web
RUN make -j$(nproc) install-plugin
RUN install -Ds /usr/local/bin/protoc-gen-grpc-web /out/usr/bin/protoc-gen-grpc-web
