--------------------------------
Summary: [C++][Python] Python FlightRPC server cannot find RE2
symbols
Key: ARROW-12865
URL: https://issues.apache.org/jira/browse/ARROW-12865
Project: Apache Arrow
Issue Type: Bug
Components: C++, FlightRPC, Python
Affects Versions: 4.0.0
Reporter: Yibo Cai
Assignee: Yibo Cai
Fix For: 5.0.0
Python Flight server fails to start if build with vendored RE2 (no system RE2
package).
It cannot find some RE2 symbols. Link gRPC with RE2 fixes the issue.
