Folks,

Has anyone tried writing netCDF files with sizes >2GB in areaDetector
with the win32-x86 architecture?

It is crashing with an assert error for me:

Assertion failed: pxp->bf_offset <= offset && offset < pxp->bf_offset +
(off_t) pxp->bf_extent, file ..\posixio.c, line 325

It works fine on linux-x86 and cygwin-x86, where I have written 5GB
files with no problems.  It is the same source code for netCDF on all
platforms, the source code is included in areaDetector.

I know netCDF can do this on Windows, because IDL's netCDF writer
produces files >4GB with no problems.

It must be some #define or compiler flag I am getting wrong, but I
wonder if anyone else has run into this an solved it?

Thanks,
Mark
