Antoine Pitrou created ARROW-2346:
-------------------------------------
Summary: [Python] PYARROW_CXXFLAGS doesn't accept multiple options
Key: ARROW-2346
URL: https://issues.apache.org/jira/browse/ARROW-2346
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.9.0
Reporter: Antoine Pitrou
Let's say I want to enable multiple warnings. I try:
{code:bash}
PYARROW_CXXFLAGS="-Wextra -Wconversion" python setup.py build
{code}
and get the following error:
{code:bash}
[ 22%] Building CXX object CMakeFiles/plasma.dir/plasma.cxx.o
g++-4.9: error: unrecognized command line option '-Wextra -Wconversion'
{code}
For some reason it seems command expansion doesn't work properly. "{{-Wextra
-Wconversion}}" is passed as a single argument instead of two separate ones...
