[Nexus] NeXus on Vista64

[freddie.akeroyd at stfc.ac.uk]

Brian,

I'm using Visual Studio 2005 with the pre-build HDF5 1.8 binaries and

H5_USE_16_API
_HDF5USEDLL_
HDF5

pre-processor symbols defined - I'm not sure how "H5_USE_16_API" and
"H5_USE_16_API_DEFAULT" differ but could that be the cause of the
problem?

Regards,  

Freddie

Freddie,

I'm using Visual Studio 2008.  I'm trying to use HDF5-1.8.5.  I had to 
download the sources for 1.8.5 because I couldn't get the pre-built 
binaries to link.  I was able to get the hdf5dll project to build 
without too much difficulty but some of the hdf5 tools failed to build 
do to linker errors.  The tools that did build work fine.  I've tried 
H5dumpdll, H5debugdll and H5diffdll--all of which use the dll I'm trying

to link into napi and all of which work as expected.

Since I'm trying to build against 1.8.5 and it looks like napi wants to 
use the 1.6 calls, I had to set H5_USE_16_API_DEFAULT to get napi to 
build.  Could this be the problem?  The NXDir application fails at the
line

NXstatus  NX5open(CONSTCHAR *filename, NXaccess am, NXhandle* pHandle)
...
         fapl = H5Pcreate(H5P_FILE_ACCESS);
...

in napi5.c.  HP5create is *not* one of the HDF5 calls whose interface 
changed between 1.6 and 1.8.  I do have working 32 bit code but it's 
built against napi 3.0 and HDF5 1.6.5.

Are you able to build against the HDF5 prebuilt 64 bit binaries?  If so,

and you're using VS2008, maybe you could send me your project file for 
building napi?

Otherwise, I think I'll try stepping back to HDF5 1.6.5 and see if that 
helps...

Thanks!

Brian
