-### Ubuntu (14.04 - Trusty Tahr)
-
-Install the minimal development tools.
-We use the `ubuntu-toolchain-r` PPA to get a modern version of CMake:
-
-```bash
-sudo apt update && sudo apt install -y software-properties-common
-sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
-sudo apt update && \
-sudo apt install -y automake cmake3 git gcc g++ libtool make pkg-config \
-        tar wget zlib1g-dev
-```
-
-#### OpenSSL
-
-Ubuntu:14.04 ships with a very old version of OpenSSL, this version is not
-supported by gRPC. We need to compile and install OpenSSL-1.0.2 from source.
-
-```bash
-cd $HOME/Downloads
-wget -q https://www.openssl.org/source/openssl-1.0.2n.tar.gz
-tar xf openssl-1.0.2n.tar.gz
-cd $HOME/Downloads/openssl-1.0.2n
-./config --shared
-make -j ${NCPU:-4}
-sudo make install
-```
-
-Note that by default OpenSSL installs itself in `/usr/local/ssl`. Installing
-on a more conventional location, such as `/usr/local` or `/usr`, can break
-many programs in your system. OpenSSL 1.0.2 is actually incompatible with
-with OpenSSL 1.0.0 which is the version expected by the programs already
-installed by Ubuntu 14.04.
-
-In any case, as the library installs itself in this non-standard location, we
-also need to configure CMake and other build program to find this version of
-OpenSSL:
-
-```bash
-export OPENSSL_ROOT_DIR=/usr/local/ssl
-export PKG_CONFIG_PATH=/usr/local/ssl/lib/pkgconfig
-```
-
-#### Protobuf
-
-We need to install a version of Protobuf that is recent enough to support the
-Google Cloud Platform proto files:
-
-```bash
-cd $HOME/Downloads
-wget -q https://github.com/google/protobuf/archive/v3.9.1.tar.gz && \
-    tar -xf v3.9.1.tar.gz && \
-    cd protobuf-3.9.1/cmake && \
-    cmake \
-        -DCMAKE_BUILD_TYPE=Release \
-        -DBUILD_SHARED_LIBS=yes \
-        -Dprotobuf_BUILD_TESTS=OFF \
-        -H. -Bcmake-out && \
-    cmake --build cmake-out -- -j ${NCPU:-4} && \
-sudo cmake --build cmake-out --target install -- -j ${NCPU:-4} && \
-sudo ldconfig
-```
-
-#### c-ares
-
-Recent versions of gRPC require c-ares >= 1.11, while Ubuntu 14.04
-distributes c-ares-1.10. Manually install a newer version:
-
-```bash
-cd $HOME/Downloads
-wget -q https://github.com/c-ares/c-ares/archive/cares-1_14_0.tar.gz && \
-    tar -xf cares-1_14_0.tar.gz && \
-    cd c-ares-cares-1_14_0 && \
-    ./buildconf && ./configure && make -j ${NCPU:-4} && \
-sudo make install && \
-sudo ldconfig
-```
-
-#### gRPC
-
-We also need a version of gRPC that is recent enough to support the Google
-Cloud Platform proto files. We can install gRPC from source using:
-
-```bash
-cd $HOME/Downloads
-wget -q https://github.com/grpc/grpc/archive/v1.23.1.tar.gz && \
-    tar -xf v1.23.1.tar.gz && \
-    cd grpc-1.23.1 && \
-    make -j ${NCPU:-4} && \
-sudo make install && \
-sudo ldconfig
-```
-
-#### googleapis
-
-We need a recent version of the Google Cloud Platform proto C++ libraries:
-
-```bash
-cd $HOME/Downloads
-wget -q https://github.com/googleapis/cpp-cmakefiles/archive/v0.1.5.tar.gz && \
-    tar -xf v0.1.5.tar.gz && \
-    cd cpp-cmakefiles-0.1.5 && \
-    cmake -DBUILD_SHARED_LIBS=YES -H. -Bcmake-out && \
-    cmake --build cmake-out -- -j ${NCPU:-4} && \
-sudo cmake --build cmake-out --target install -- -j ${NCPU:-4} && \
-sudo ldconfig
-```
-
-#### googletest
-
-We need a recent version of GoogleTest to compile the unit and integration
-tests.
-
-```bash
-cd $HOME/Downloads
-wget -q https://github.com/google/googletest/archive/release-1.10.0.tar.gz && \
-    tar -xf release-1.10.0.tar.gz && \
-    cd googletest-release-1.10.0 && \
-    cmake -DCMAKE_BUILD_TYPE="Release" -DBUILD_SHARED_LIBS=yes -H. -Bcmake-out && \
-    cmake --build cmake-out -- -j ${NCPU:-4} && \
-sudo cmake --build cmake-out --target install -- -j ${NCPU:-4} && \
-sudo ldconfig
-```
-
-#### Compile and install the main project
-
-We can now compile, test, and install `google-cloud-cpp-common`.
-
-```bash
-cd $HOME/project
-cmake -H. -Bcmake-out
-cmake --build cmake-out -- -j "${NCPU:-4}"
-cd $HOME/project/cmake-out
-ctest -LE integration-tests --output-on-failure
-sudo cmake --build . --target install
-```
