[orecham]

Required information

Operating system: MacOS 10.15

Compiler version: GCC 8

Observed result or behaviour: DDS Gateway build fails due to inability to find boost dependency. Error message:

Expected result or behaviour: Boost dependency to be found and DDS Gateway to be successfully built.

Conditions where it occurred / Performed steps: Run the github workflow for MacOS with the with-dds-gateway option.

Attempts to fix

1. Attempted to install boost via Homebrew, however dependency is still not found and the build fails with the same error.

2. Attempted to build boost from source and manually install, dependency is still not found and the build fails with the same error. Here are the workflow steps used for building from source (including caching):

     - name: Load boost from cache
       id:   cache-boost
       uses: actions/cache@v2
       with:
         path: $GITHUB_WORKSPACE/build/dependencies/boost/install/
         key: ${{ runner.os }}-boost
   
     - name: Build boost from source
       if: steps.cache-boost.outputs.cache-hit != 'true'
       run: |
         cd $GITHUB_WORKSPACE
         mkdir -p build
         cd build
         wget https://dl.bintray.com/boostorg/release/1.73.0/source/boost_1_73_0.tar.gz
         tar xf ./boost_1_73_0.tar.gz
         cd ./boost_1_73_0
         ./bootstrap.sh --prefix=$GITHUB_WORKSPACE/build/dependencies/boost/install/
         ./b2
         ./b2 install
   
     - name: Copy boost to prefix path
       run: |
         mkdir -p $GITHUB_WORKSPACE/build/dependencies/install/
         cp $GITHUB_WORKSPACE/build/dependencies/boost/install/* $GITHUB_WORKSPACE/build/dependencies/install/
         ls $GITHUB_WORKSPACE/build/dependencies/install/
