If this isn't the right place to ask, please let me know where to direct this question:
I'm trying to build a slightly modified version of the 9.0.0 tag for arrow (particularly Pyarrow). Walking through the build steps (below), I have run into a problem where the arrow c++ library has symbols that include the tag Bcxx11, but the cython libraries aren't generating that flag. The symbol resolution fails at runtime once the library loads. Particularly these two symbols in python/build/lib.linux-x86_64-3.8/pyarrow/ lib.cpython-38-x86_64-linux-gnu.so U _ZNK5arrow8DataType18ComputeFingerprintEv U _ZNK5arrow8DataType26ComputeMetadataFingerprintEv Don't resolve. All of the corresponding symbols in libarrow_so.900 look like this (not the addition of the B5cxx11Ev): 00000000006addc0 T _ZNK5arrow8DataType18ComputeFingerprintB5cxx11Ev 00000000006ae050 T _ZNK5arrow8DataType26ComputeMetadataFingerprintB5cxx11Ev I've tried building with explicit flags to encourage the libraries to include the cxx11 symbol (in python/CMakeLists.txt). That doesn't seem to impact this issue: set (CMAKE_CXX_STANDARD 11) set (CMAKE_CXX_STANDARD_REQUIRED ON) set (CMAKE_CXX_EXTENSIONS OFF) I also added export PYARROW_CXXFLAGS="-std=c++11" for the wheel build of pyarrow (no effect). I would appreciate any guidance on how to build a clean wheel file of pyarrow that includes my small code changes.
