Building the services

  1. Clone this repo.

    git clone --recursive https://github.com/Azure/iot-identity-service
cd iot-identity-service/

  2. Install build dependencies.

    • gcc
    • libclang1
    • llvm-config
    • make
    • openssl headers and libraries
    • pkg-config

    Check /ci/install-build-deps.sh for the exact names of the packages for your distro that contain these components.

  3. Install rustup. Ensure that ~/.cargo/bin is in $PATH. The exact toolchain used to build this repository will automatically be downloaded later if necessary.

  4. Install bindgen and cbindgen. Again, check /ci/install-build-deps.sh for the exact command and versions.

  5. Build the services.

    make

    If the build fails with an error like:

    /usr/include/limits.h:124:16: fatal error: 'limits.h' file not found

    ... this is because bindgen got confused by the default limits.h that ships with gcc. Instead, you need to point it to an alternative one that doesn't use include_next. Find it with:

    find /usr/lib*/gcc/ -name limits.h | grep include-fixed

    This will print something like /usr/lib/gcc/x86_64-linux-gnu/7/include-fixed/limits.h

    Then export an env var to tell bindgen (and in turn, libclang) about this directory.

    export BINDGEN_EXTRA_CLANG_ARGS='-isystem /usr/lib/gcc/x86_64-linux-gnu/7/include-fixed'

    Then invoke make again.
