[Nexus] NeXus on Vista64

[freddie.akeroyd at stfc.ac.uk]

Brian,

We run 64 bit NeXus / HDF5 on Vista as part of our instrument control
system - I have currently only compiled the library and not the
applications for 64 bit, but the resulting files can be read by 32bit
NeXus applications. I used Visual Studio to compile for 64 bit - are you
using that or MinGW? Can you read your HDF5 generated NeXus files with a
32bit rather than 64bit NeXus application?  

Regards,

Freddie

Has anyone built napi for 64 bit windows?  I think I've managed to do it

but I'm getting errors when trying to open HDF5 files from napi.

As a test, I built NXDir for 64 bit.  If I pass it an HDF4 file, it 
works fine.  If I pass it an HDF5 file I get the error "ERROR: cannot 
open file: test.h5"  I'm 90% certain my HDF5 build is OK.  H5dump works 
without error and it's functionally doing the same thing as NXDir.  I've

never used NXDir before so I went on to build my own code which calls 
napi and I get the same results--HDF4 works fine, HDF5 fails in the same

manner.

I've tried both napi 4.2.0 and 4.2.1 and both fail the same way.

Does anyone use napi 4.2.1 with HDF5?  Maybe there's a bug in napi?

Any help would be greatly appreciated.

Thanks!

Brian
