> Reporter: Anders Wind
> Priority: Major

> Hi, I'm trying to upgrade to arrow-cpp 6.0 and I have some code which
> compiles with 5.0.0:
> {code:java}
> inline void write_table(const std::shared_ptr<arrow::Table>& table, const
> std::string& file)
> {
> auto arrow_fs_ = arrow::fs::LocalFileSystem();
> std::string corrected_path =
> value_or_throw(arrow_fs_.NormalizePath(file));
> auto stream_opt = arrow_fs_.OpenOutputStream(corrected_path);
> auto status = arrow::ipc::feather::WriteTable(*table,
> value_or_throw(stream_opt).get());
> ALCC_ARROW_STATUS_CHECK(status);
> }{code}
>
> The following line is the root of the compile stack trace
>
> {code:java}
> auto stream_opt = arrow_fs_.OpenOutputStream(corrected_path);{code}
>
> It gives me the following error:
> {code:java}
