This looks like the result if the hdf5 library and tool is not all using shared
libraries.

Subject: Re: [Hdf-forum] Dynamic filters on Windows
Hi Werner,
Yeah, the different in the number of parameters is curious. And no, all the
hdf5-blosc plugin versions take 7 params (4 reserved, hence the 4 0s) and 3 for
the actual compression parameters (complevel, shuffle, codec), so I don't quite
understand why 8 (with 5 0s) works for me, but it is indeed the required number
on Unix boxes (using HDF5 1.8.x there, so maybe the difference is just because
HDF5 1.8.x and 1.10.x).
I have just tried with 7 params on Windows, but I am having the same problem
again:

Hi Francesc,
I got it to run with 1.10.1 and GCC 7.1 under MSYS2, kind of, but the

If you want to try my configuration, try this in MSYS2:
svn co https://subversion.assembla.com/svn/FiberHDF5/hdf5; cd hdf5;
mingw32-make -j12
Maybe I am using an older version of blosc that doesn't like 8 parameters?

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.

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!

<wer...@cct.lsu.edu<mailto:wer...@cct.lsu.edu>>:
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.

libH5Zblosc.dll, but I have tried with H5Zblosc.dll and blosc.dll with no

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

place,
but no luck.
I tried with HDF5 1.8.12 and 1.10.1, with same results. Finally, if it is of

As a suggestion, it may help to debug situations like this if the HDF5

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,
