arrow-cpp-conan-example

Example of using conan to use a customized version of libarrow in a C++ project.

This specific example builds libarrow with:

• Flight RPC
• Parquet

Pre-requisites

• A source checkout of the arrow repository
• A C++ compiler
• cmake
• conan

Building

1. Build a Conan recipe for libarrow

   • Set the ARROW_HOME environment variable

     export ARROW_HOME=$ARROW_SOURCE_DIR

   • Create the Conan recipe

     cd $ARROW_HOME
     conan create ci/conan/all arrow/10.0.0@ \
         -o arrow:with_flight_rpc=True \
         -o arrow:parquet=True \
         --build missing \
         --require-override protobuf/3.21.4

2. Build the example project

   From this directory, run:

   mkdir build
   cd build
   conan install .. \
       -o arrow:with_flight_rpc=True \
       -o arrow:parquet=True \
       --build missing
   cmake ..
   make

Running

./bin/example

You should get the following output:
