Wes McKinney created ARROW-8623: ----------------------------------- Summary: [C++][Gandiva] Reduce use of Boost, remove Boost headers from header files Key: ARROW-8623 URL: https://issues.apache.org/jira/browse/ARROW-8623 Project: Apache Arrow Issue Type: Improvement Components: C++, C++ - Gandiva Reporter: Wes McKinney Fix For: 1.0.0
Boost is currently a transitive dependency of many of Gandiva's public header files. I suggest the following: * Do not include Boost transitively in any installed header file * Reduce usages of Boost altogether On the latter point, most usages of Boost can be trimmed by having a {{hash_combine}} function inside the Arrow codebase. See results of grepping the codebase https://gist.github.com/wesm/190006d91628e6bf7c04deb596a52cff It seems that Boost cannot be easily eliminated altogether at the present moment because of a use of Boost.Multiprecision ({{int256_t}}). At some point someone may want to implement sufficient 256-bit integer functions so that we don't have to depend on Boost.Multiprecision -- This message was sent by Atlassian Jira (v8.3.4#803005)
