FROM ubuntu:18.04 AS devtools

# Please keep the formatting in these commands, it is optimized to cut & paste
# into the README.md file.

## [START INSTALL.md]

# Install the minimal development tools:

# ```bash
RUN apt update && \
    apt install -y build-essential cmake git gcc g++ cmake \
        libc-ares-dev libc-ares2 libcurl4-openssl-dev libssl-dev make \
        pkg-config tar wget zlib1g-dev
# ```

# #### Protobuf

# While protobuf-3.0 is distributed with Ubuntu, the Google Cloud Plaform proto
# files require more recent versions (circa 3.4.x). To manually install a more
# recent version use:

# ```bash
WORKDIR /var/tmp/build
RUN wget -q https://github.com/google/protobuf/archive/v3.9.0.tar.gz
RUN tar -xf v3.9.0.tar.gz
WORKDIR /var/tmp/build/protobuf-3.9.0/cmake
RUN cmake \
        -DCMAKE_BUILD_TYPE=Release \
        -DBUILD_SHARED_LIBS=yes \
        -Dprotobuf_BUILD_TESTS=OFF \
        -H. -Bcmake-out
RUN cmake --build cmake-out --target install -- -j $(nproc)
RUN ldconfig
# ```

# #### gRPC

# Likewise, Ubuntu has packages for grpc-1.3.x, but this version is too old for
# the Google Cloud Platform APIs:

# ```bash
WORKDIR /var/tmp/build
RUN wget -q https://github.com/grpc/grpc/archive/v1.22.0.tar.gz
RUN tar -xf v1.22.0.tar.gz
WORKDIR /var/tmp/build/grpc-1.22.0
RUN make -j $(nproc)
RUN make install
RUN ldconfig
# ```

FROM devtools AS install

# #### googleapis

# Finally we can install `googleapis`.

# ```bash
WORKDIR /home/build/cpp-cmakefiles
COPY . /home/build/cpp-cmakefiles
RUN cmake -H. -Bcmake-out
RUN cmake --build cmake-out -- -j $(nproc)
WORKDIR /home/build/cpp-cmakefiles/cmake-out
RUN cmake --build . --target install
# ```

## [END INSTALL.md]

# Verify that the installed files are actually usable
RUN /home/build/cpp-cmakefiles/ci/test-install/compile-test-projects.sh
