Hello Alex,

no issues, happy to help and nice to see that your problem has been fixed with the change of the configuration. If ever other problems come up with the conda package of Arrow, feel free to open an issue at https://github.com/conda-forge/arrow-cpp-feedstock This is the best place to post them.

Hi Uwe,

I apologize for taking your time and thank you for confirming that boost-cpp is no longer a runtime dependency. I see now that the issue was that our .condarc file placed the conda/anaconda channel about conda/conda-forge channel causing it to download from that channel which for some reason must still list boost-cpp as a dependency. Explicitly using conda-forge as the channel via "conda install -c conda-forge pyarrow=2.0.0" now no longer pulls in boost-cpp.

Thanks again,

Hello Alex,

continuing this here instead of StackOverflow. Can you share your source of conda packages: Do you use conda-forge? Can you share the output of `conda list` of your current environment?

What stucks me is that we have never built pyarrow on conda-forge against boost-cpp 1.73, only 1.72 and 1.74. We though have removed boost-cpp as a runtime dependency so I suspect the boost-cpp version change comes from packages that aren't from conda-forge but from conda-forge.

I am in the process of upgrading a project from pyarrow 0.8.0 to 2.0.0. As part of this upgrade I see boost-cpp 1.63 is installed into the environment. I have a number of libraries that were linked against an older version of boost-cpp and so I would like to avoid pulling in this new version of boost-cpp.

I am generally looking for guidance on how to best handle this situation. Running ldd on the libarrow*.so's installed into our conda env I can't actually see any references to the libboost*.so's.

This leads to my first question: is boost-cpp is a runtime requirement for pyarrow 2.0.0? (maybe only for certain components?) If it is a runtime requirement is there a recipe for building pyarrow/arrow-cpp with static linkings or any version of pyarrow that can be built without boost-cpp?

I am open to any suggestions on how to get around the boost-cpp dependency.
