pyarrow-core library uses default visibility instead of hidden #123
Description
Solution to issue cannot be found in the documentation.
- I checked the documentation.
Issue
It looks like the pyarrow-core library exposes symbols that are not explicitly exported by Arrow:
$ nm -CD libarrow.so | grep TemporalScalar
00000000002e3e20 t arrow::TemporalScalar<arrow::Date32Type>::~TemporalScalar()
00000000002e3440 t arrow::TemporalScalar<arrow::Date32Type>::~TemporalScalar()
00000000002e3440 t arrow::TemporalScalar<arrow::Date32Type>::~TemporalScalar()
00000000002e4320 t arrow::TemporalScalar<arrow::Date64Type>::~TemporalScalar()
00000000002e30c0 t arrow::TemporalScalar<arrow::Date64Type>::~TemporalScalar()
...Setting the CXXFLAG -fvisibility-hidden should get rid of these and help shave off some package size (locally I saw about a 5% reduction)
