By default, the image runs the Buildkite Agent, however one 12# can also just start the image with a shell to debug CI failures. 13# 14# To start a Buildkite Agent, run it as: 15# $ docker run --env-file secrets.env -it $(docker build -q .) 16# 17# The environment variables in `secrets.env` must be replaced by the actual 18# tokens for this to work. These should obviously never be checked in. 19# 20# If you're only looking to run the Docker image locally for debugging a 21# build bot, see the `run-buildbot-container` script located in this directory. 22# 23# A pre-built version of this image is maintained on DockerHub as ldionne/libcxx-builder. 24# To update the image, rebuild it and push it to ldionne/libcxx-builder (which 25# will obviously only work if you have permission to do so). 26# 27# $ docker build -t ldionne/libcxx-builder . 28# $ docker push ldionne/libcxx-builder 29# 30 31FROM ubuntu:bionic 32 33# Make sure apt-get doesn't try to prompt for stuff like our time zone, etc. 34ENV DEBIAN_FRONTEND=noninteractive 35 36RUN apt-get update && apt-get install -y bash curl 37 38# Install various tools used by the build or the test suite 39RUN apt-get update && apt-get install -y ninja-build python3 python3-sphinx python3-distutils git gdb 40RUN apt-get update && apt-get install -y libc6-dev-i386 # Required to cross-compile to 32 bits 41 42# Install the most recently released LLVM 43RUN apt-get update && apt-get install -y lsb-release wget software-properties-common 44RUN wget https://apt.llvm.org/llvm.sh -O /tmp/llvm.sh 45RUN bash /tmp/llvm.sh 46RUN LLVM_VERSION=$(find /usr/bin -regex '^.+/clang-[0-9.]+$') && LLVM_VERSION=${LLVM_VERSION#*clang-} && echo "LLVM_VERSION=$LLVM_VERSION" > /tmp/env.sh 47RUN ln -s $(find /usr/bin -regex '^.+/clang\+\+-[0-9.]+$') /usr/bin/clang++ && [ -e $(readlink /usr/bin/clang++) ] 48RUN ln -s $(find /usr/bin -regex '^.+/clang-[0-9.]+$') /usr/bin/clang && [ -e $(readlink /usr/bin/clang) ] 49 50# Install the not-yet-released LLVM 51RUN . /tmp/env.sh && echo "LLVM_TOT_VERSION=$(($LLVM_VERSION + 1))" >> /tmp/env.sh 52RUN . /tmp/env.sh && bash /tmp/llvm.sh ${LLVM_TOT_VERSION} 53RUN . /tmp/env.sh && ln -s /usr/bin/clang++-${LLVM_TOT_VERSION} /usr/bin/clang++-tot && [ -e $(readlink /usr/bin/clang++-tot) ] 54RUN . /tmp/env.sh && ln -s /usr/bin/clang-${LLVM_TOT_VERSION} /usr/bin/clang-tot && [ -e $(readlink /usr/bin/clang-tot) ] 55 56# Install clang-format 57RUN . /tmp/env.sh && apt-get install -y clang-format-$LLVM_VERSION 58RUN ln -s $(find /usr/bin -regex '^.+/clang-format-[0-9.]+$') /usr/bin/clang-format && [ -e $(readlink /usr/bin/clang-format) ] 59RUN ln -s $(find /usr/bin -regex '^.+/git-clang-format-[0-9.]+$') /usr/bin/git-clang-format && [ -e $(readlink /usr/bin/git-clang-format) ] 60 61# Install a recent GCC 62RUN add-apt-repository ppa:ubuntu-toolchain-r/test 63RUN apt-get update && apt install -y gcc-10 g++-10 64RUN ln -f -s /usr/bin/g++-10 /usr/bin/g++ && [ -e $(readlink /usr/bin/g++) ] 65RUN ln -f -s /usr/bin/gcc-10 /usr/bin/gcc && [ -e $(readlink /usr/bin/gcc) ] 66 67# Install a recent CMake 68RUN wget https://github.com/Kitware/CMake/releases/download/v3.18.2/cmake-3.18.2-Linux-x86_64.sh -O /tmp/install-cmake.sh 69RUN bash /tmp/install-cmake.sh --prefix=/usr --exclude-subdir --skip-license 70RUN rm /tmp/install-cmake.sh 71 72# Change the user to a non-root user, since some of the libc++ tests 73# (e.g. filesystem) require running as non-root.
