             Summary: [Gandiva] static jni library broken after decimal changes
                 Key: ARROW-4274
                 URL: https://issues.apache.org/jira/browse/ARROW-4274
             Project: Apache Arrow
          Issue Type: Bug
          Components: Gandiva
            Reporter: Pindikura Ravindra
            Assignee: Pindikura Ravindra


With the decimal changes, there can be cpp calls from the IR code. The symbols for these  need to be visible in the gandiva cpp library. but, the jni library makes visible only a limited set of symbols from gandiva (the ones specified in src/gandiva/jni/symbols.map).

This breaks  if the jni library links with the static-libstdc++ (dremio builds the gandiva binary with stdc++ statically linked) due to two reasons
 # The cpp symbols like std::ios_base::init are not exported via symbols.map. This causes LLVM to complain that there is are unresolved symbols.
 # Also, there is a problem with exceptions (string_view.hpp can throw exceptions) - This alsi causes LLVM to complain that unwindResume is unresolved.
