Hello Andrea, Thank you for writing to us, and my apologies for the delayed response; I have been out of the office. The netCDF-CXX4 API was contributed to us by a third party, as a replacement for the old API, and you are correct that the constructor for parallel I/O (enhanced model) appears to have gone missing. I will fix this for the upcoming release of the C++ API. In the meantime, you could use the C api, or an older version of the C++ API. My apologies for not having a better answer, but you are the first person to point this out! I will correct this ASAP. -Ward > Full Name: Andrea Laruelo > Email Address: address@hidden > Organization: Magellium > Package Version: 4.3.0 > Operating System: Linux > Hardware: > Description of problem: > > Dear NetCDF Support Team, > > I am currently working in the development of a C++ library that uses > NetCDF-4 files (enhanced model) to store scientific data.
