I think that the GLib build with Meson failure isn't a Meson problem. Maybe, the Python environment that runs `/home/travis/miniconda/bin/meson` doesn't include Meson by `pip install meson` https://travis-ci.org/apache/arrow/jobs/425563611#L1493 .
The following debug print may help us: ```shell which meson head $(which meson) $(head -n1 $(which meson) | sed -e 's/^#! *//') -c 'import os; import sys; import pprint; pprint.pprint([list(os.walk(path)) for path in sys.path])' ``` ``` [ Full content available at: https://github.com/apache/arrow/pull/2453 ] This message was relayed via gitbox.apache.org for [email protected]
