Hi all, Werner is correct. You could build the thread-safe + static library with ALLOW_UNSUPPORTED (under the advanced options if you use ccmake) and implement the thread attach/detach code yourself. You can check out the code in DllMain() at the end of src/H5.c to see what we do, which is actually quite minimal. Basically, you just have to initialize and clean up thread-local storage when you attach and detach threads, respectively.

Hi Isaac, as far as I know the problem with static libraries is not the threadsafety of HDF5 itself, the code is the same, but the initialization & cleanup code. With a shared library, there are such defined entry points when loading and unloading a shared library which does a clean initialization and cleanup, but with a static library there is no such option. If you'd want to use threadsafe HDF5 with the static library, you would need to explicitly call the initialization & cleanup, for instance from your main program or from another shared library at startup/cleanup. I'm not sure whether HDF5 1.8.17 explicitly supports such, it may be possible but not implemented that way.

Is this true with 1.8.17 (or the latest hdf version)? Is thread safe available for hdf static in windows?
