Severity: serious
Hello,
[I'm not quite sure if this should be filed against netcdf instead, or
against both, I'll leave it up to you]
quite simply, after you close a NetCDF file you can't open HDF5 files
anymore. This is a short test case that consistently reproduces the
issue for me:
// Build with:
// g++ -o test-nch5 test-nch5.cc -lnetcdf_c++ -lnetcdf -lhdf5_cpp -lhdf5
// See http://hdf-forum.184993.n3.nabble.com/nc-close-causes-problems-for-H5Fopen-td1019191.html
#include <H5Cpp.h>
#include <netcdfcpp.h>
int main(int argc, const char* argv[])
{
try {
NcFile nc("test-nch5-data.nc", NcFile::Replace);
// Comment out the next line to be able to open the file
nc.close();
H5::H5File h5("test-nch5-data.h5", H5F_ACC_TRUNC);
} catch (H5::FileIException& e) {
e.printError(stderr);
return 1;
}
return 0;
}
The problem also shows when existing files are opened read only. The
test case has a link to an hdf-forum post about this same problem, but
had no answers as far as I can see.
I am the author of a software that has to deal both with NetCDF and with
HDF5 files, and this is quite a killer :(
Ciao,
Enrico
