[Nexus-developers] [Nexus] Files lagrer tha 2GB

[POIRIER Stephane]

Indeed the problem is that the NeXus library is not compiled with large files support. It is required for the function determineFileType() in napi.c, in which there is a call to fopen().
So the question is how to compile the NeXus library with the large file support ? I didn't see any option to do this in the file named 'configure' in the source distribution.

Thanks for your attention,

stephane

Just 2 things to check:
1. use a file system capable of handling large files (XFS, JFS are know to work)

2. try compiling  HDF+Nexus with
-D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
