Hi,
Today I spent some more time on this issue, and I recompiled
everything (the Blosc library and its plugin) against HDF5 1.10.1
(the binaries from hdfgroup.org <http://hdfgroup.org>) in 64 bit
mode. Again, I can read Blosc-compressed HDF5 files with h5ls and
h5dump (so I am pretty sure that the plugin is correctly compiled),
but h5repack is still failing:
"""

At this point, I don't know what to do. I am using VS2017 Community

plugin?
Also, I have tried to use MingW64 to compile the plugin, but cmake
has difficulties in finding the HDF5 installation:

I'm using 1.8.17, evidently.
Btw, the restriction with the lib-prefix has the advantage that
the HDF5 plugin loader does not look at DLL's such as
"blosc.dll", it would not even try to load it as a plugin. Just
something better than "lib" would probably be preferable, and
independent of platform and compiler. I guess in your version it
even tries to load the blosc.dll itself as a plugin - which could
lead to issues if such a plugin would contain some startup code
like global c++ constructors or code in DllMain which does
"something". That's unlikely to be related to your problem
though, I don't see from the output what the problem could be, it
works for me.

Werner, I think the lib- prefix does not apply to my case

agreed that HDF5 taking different conventions depending on
whether a MSVC or GCC-based is a bit confusing.
BTW, although the h5dump can read blosc files with the plugin,
ptrepack cannot create them on Windows:

Hi Francesc,
it took me a while to figure out this detail, too, I had
the blosc.dll in the PATH at first, and it seems to work
under some circumstances but not others... not entirely
clear to me when it needs to be in the PATH or in the
calling's DLL's directory outside of the PATH.
There's some code in H5PL.c that checks for a lib prefix:
#ifndef __CYGWIN__
if(!HDstrncmp(dp->d_name, "lib", (size_t)3) &&
(HDstrstr(dp->d_name, ".so") ||
HDstrstr(dp->d_name, ".dylib"))) {
#else
...
#endif
So I guess in your case that prefix check did not apply,
whereas for me using gcc under windows it did. Thus it seems
best for compatibility to keep the plugins named with lib-
starting under Windows, once compiled that C code should not
matter whether it was produced by GCC or MSC. Otherwise yes,
the name does not matter indeed.

Hi Werner,
Right, what I was missing was basically moving the
blosc.dll library into the HDF5 plugin directory. I thought
that putting blosc.dll in a directory in the %PATH% was
going to be enough, but apparently this is not the case (I
suppose this is a Windows trickery).
For what is worth, the name of the DLL plugin is not that
important as I have tried with libHDF5blosc.dll,
libH5Zblosc.dll, H5Zblosc.dll and even blosc_plugin.dll and
all of them work. Apparently the HDF5 library tries all
the DLLs in the plugin directory and uses the one that
registers the necessary filter ID; pretty smart.
Thanks so much!

Just to add:
under windows, the plugins need to start with lib as
prefix. It's technically not required, but the HDF5
plugin loader expects that. So the liblz4.dll in my
plugins dir is the LZ4 plugin,the libHDF5blosc.dll the
blosc-filter; the blosc.dll is used by the blosc filter
and needs to be in the same directory if compiled as
dynamic library as well.

Hi,
I am using HDF5 with blosc dynamic plugin loading

The blosc.dll is the blosc library, libHDF5blosc.dll
is the HDF5 plugin using that library.
I'm using Mingw64, which is gcc 6.3 under MSYS2 .

ut I have no clues on 1) what directory the dynamic
plugin machinery in HDF5 is looking at and 2) which
name the DLL should have (as per manual, I am using
libH5Zblosc.dll, but I have tried with H5Zblosc.dll
and blosc.dll with no success).
I have also tried to use the HDF5_PLUGIN_PATH
environment variable, so as to direct the plugin
machinery in HDF5 to look into the specific
%ALLUSERSPROFILE%/hdf5/lib/plugin
place,
but no luck.
I tried with HDF5 1.8.12 and 1.10.1, with same
results. Finally, if it is of any help, I am using
Windows 10 64 bit.
As a suggestion, it may help to debug situations
like this if the HDF5 backtrace of the plugin
machinery would provide info about 1) which directory
it is looking at for finding the HDF5 plugin and 2)
the name of the DLL that it is trying to load.
Thanks in advance,
