Static libraries scripts

Static libraries are built using an fPIC GHC created with these scripts by this job.

The script is consumed by various Docker build jobs, usually as a designated "build static libraries" stage before the "actual" build stage:

# Build static libraries in base image 'concordium/static-libraries'.
FROM concordium/static-libraries:latest as static-builder
COPY . /build
ARG ghc_version
WORKDIR /build
RUN GHC_VERSION="${ghc_version}" \
      /build/scripts/static-libraries/build-static-libraries.sh

# Build binaries in base image 'concordium/base'.
FROM concordium/base:latest
COPY . /build
WORKDIR /build
# Copy static libraries that were built by the 'static-builder' into the correct place
# (/build/concordium-node/deps/static-libs/linux).
ARG ghc_version
COPY --from=static-builder "/build/static-consensus-${ghc_version}.tar.gz" /tmp/static-consensus.tar.gz
RUN tar -C /tmp -xf /tmp/static-consensus.tar.gz && \
    mkdir -p /build/concordium-node/deps/static-libs && \
    mv /tmp/target /build/concordium-node/deps/static-libs/linux && \
    rm /tmp/static-consensus.tar.gz
# Build binaries ...

It's considered a best practice to let this be followed by a final stage that copies the build artifacts into a fresh image.

Replacement of integer-simple

Prior to concordium/static-libraries version 0.30 the included GHC was using the integer library integer-simple. Starting from version 0.30, the default GMP integer library is used. The static build of concordium-node up until version 1.1.3 (inclusive) depends on integer-simple.
