Hello, On Ubuntu, I managed to get a local external (i.e., to Arrow) project to build against a locally and custom-built Arrow project working using the following:
* Locally build Arrow and install it to a directory $ARROW_ROOT_DIR * Configure the external project build using: cmake -DARROW_CMAKE_DIR=$ARROW_ROOT_DIR/lib/cmake/arrow * Include the following cmake-directives in the external project (which uses Arrow, ArrowDataset, and Parquet): set(CMAKE_MODULE_PATH ${ARROW_CMAKE_DIR}) set(Arrow_DIR ${ARROW_CMAKE_DIR}) set(ArrowDataset_DIR ${ARROW_CMAKE_DIR}) set(Parquet_DIR ${ARROW_CMAKE_DIR}) * Build the external project and run the executable with LD_LIBRARY_PATH=$ARROW_ROOT_DIR/lib For some reason, I had to set a "*_DIR" cmake-variable for each Arrow dependency, which is not as clean as one would like. Without these, cmake fails to find the local Arrow project install and mixes it up with a system-wide Arrow installation, leading to the external project failing to build. If you know of a cleaner way to configure the external project, please advise. Thanks, Yaron. ________________________________ From: Li Jin <ice.xell...@gmail.com> Sent: Thursday, February 3, 2022 3:40 PM To: dev@arrow.apache.org <dev@arrow.apache.org> Cc: rt...@hotmail.com <rt...@hotmail.com> Subject: [C++] Build/Link against master / custom branch Hello! We are trying to write some program similar to: https://github.com/apache/arrow/blob/master/cpp/examples/arrow/execution_plan_documentation_examples.cc to test Arrow compute engine performance. We would like to build the example against Arrow default because we added a "square root" function to it. I wonder if there is an easy way to build/link my program against github master / custom branch or if we should put it under cpp/examples/arrow and compile arrow lib and the main program together? Thanks, Li
