Hi, Hope you are all well!
I am struggling to get the minimal sample app to work & am hoping for tips to move forward *Setup*: Windows 10, Visual Studio 2019, Arrow 9.0.0 installed via miniconda. Thanks to the previous tip, I can now successfully build the arrow minimal_build <https://arrow.apache.org/docs/9.0/cpp/examples/cmake_minimal_build.html> example. However when I try to run the sample it always fails at the arrow::io::ReadableFile::Open(csv_filename) step. My code snippet is below & trying to debug, the returned status code does not seem useful. Appreciate any guidance to understand what is wrong. const char* csv_filename = "C:\\Repos\\arrow\\cpp\\examples\\minimal_build\\Debug\\test.csv"; auto res = arrow::io::ReadableFile::Open(csv_filename); // full path to existing file if (!res.ok()) { std::cout << res.status().IsIOError(); // returns 0 std::cout << res.status().IsUnknownError(); // returns 0 std::cout << res.status().detail(); // returns 000000 std::cout << res.status().CodeAsString(); // causes app to crash with access violation std::cout << res.status().message(); // returns gibberish } Regards Prasad On Fri, Nov 4, 2022 at 7:06 PM Raghavendra Prasad <[email protected]> wrote: > Thank you and have a great weekend > > On Fri, 4 Nov 2022 at 6:25 pm Sutou Kouhei <[email protected]> wrote: > >> Hi, >> >> > Just wondering if you know when arrow-cpp v10.0.0 packages will be >> > available via conda mechanism? >> >> This is work in progress.
