Antoine Pitrou created ARROW-17580: -------------------------------------- Summary: [Doc][C++][Python] Unclear how to influence compilation flags Key: ARROW-17580 URL: https://issues.apache.org/jira/browse/ARROW-17580 Project: Apache Arrow Issue Type: Bug Components: C++, Documentation, Python Reporter: Antoine Pitrou
Frequently people need to customize compilation flags for C++ and/or C files. Unfortunately, both for Arrow C++ and PyArrow, it is very difficult to find out the proper way to do this. For Arrow C++, it seems {{ARROW_CXXFLAGS}} should be passed to CMake, while the {{CXXFLAGS}} environment variable is ignored (it probably shouldn't?). For PyArrow, I have not found a way to do it. The {{CXXFLAGS}} environment is ignored, and the {{PYARROW_CXXFLAGS}} has two problems: * it is only recognized for Cython-generated files, not for PyArrow C++ sources * it only affects linker calls, while it should actually affect compiler calls -- This message was sent by Atlassian Jira (v8.20.10#820010)
