FROM centos:7 AS devtools

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

## [START INSTALL.md]

# First install the development tools and OpenSSL. The development tools
# distributed with CentOS (notably CMake) are too old to build
# `cpp-cmakefiles`. In these instructions, we use `cmake3` obtained from
# [Software Collections](https://www.softwarecollections.org/).

# ```bash
RUN rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
RUN yum install -y centos-release-scl
RUN yum-config-manager --enable rhel-server-rhscl-7-rpms
RUN yum makecache && \
    yum install -y automake cmake3 curl-devel gcc gcc-c++ git libtool \
        make openssl-devel pkgconfig tar wget which zlib-devel
RUN ln -sf /usr/bin/cmake3 /usr/bin/cmake && ln -sf /usr/bin/ctest3 /usr/bin/ctest
# ```

# #### Protobuf

# Likewise, manually install protobuf:

# ```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
# ```

# #### c-ares

# Recent versions of gRPC require c-ares >= 1.11, while CentOS-7
# distributes c-ares-1.10. Manually install a newer version:

# ```bash
WORKDIR /var/tmp/build
RUN wget -q https://github.com/c-ares/c-ares/archive/cares-1_15_0.tar.gz
RUN tar -xf cares-1_15_0.tar.gz
WORKDIR /var/tmp/build/c-ares-cares-1_15_0
RUN ./buildconf && ./configure && make -j $(nproc)
RUN make install
RUN ldconfig
# ```

# #### gRPC

# Can be manually installed using:

# ```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
ENV PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/lib64/pkgconfig
ENV LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib64
ENV PATH=/usr/local/bin:${PATH}
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
