---------------------------------------
Summary: [R] Build fails if dataset enabled but parquet is not
Key: ARROW-11994
URL: https://issues.apache.org/jira/browse/ARROW-11994
Project: Apache Arrow
Issue Type: Bug
Components: R
Reporter: Neal Richardson
Following ARROW-11735; discovered while working on ARROW-10734. The
arrow::dataset::ParquetFileFormat and related classes require both dataset and
parquet. The {{#if defined}} logic in r/src/dataset.cpp is right and both are
required, but in the wrapping that is generated for arrowExports.cpp, we only
use the annotation on the functions, {{[[dataset::export]]}} to wrap. So the
ParquetFileFormat methods in arrowExports.cpp are if defined
ARROW_R_WITH_DATASET and fail if parquet is not available.
Not a priority to fix (for Solaris I can turn off ARROW_DATASET and avoid
this), just wanted to note it in case we need to revisit this wrapping logic
later anyway. cc [~icook]
