----------------------------- Captured stderr call -----------------------------
Blosc has not been compiled with '(null)' compression support.
Looks like c-blosc has been compiled without support for snappy compression.

It is possible that the result of the Brunsli repacking is platform or version specific.

Hello,
blosc on openSUSE have been compiled with
-DPREFER_EXTERNAL_SNAPPY=ON \
-DPREFER_EXTERNAL_ZLIB=ON \
-DPREFER_EXTERNAL_ZSTD=ON \
-DPREFER_EXTERNAL_LZ4=ON \
-DBUILD_STATIC=OFF
https://build.opensuse.org/package/view_file/openSUSE:Factory/blosc/blosc.spec?expand=1
Which seems to enable snappy, but is using the PREFER_EXTERNAL flag the good way to do it?
I'm not sure what you meant by Brunsli repacking is platform or version specific, can you expand on that?
Also, I forgot to mention that I apply a patch, to fix zopfli not found and enable other stuff if that make a difference.

Try to build c-blosc with -DDEACTIVATE_SNAPPY=OFF
what you meant by Brunsli repacking is platform or version specific
Brunsli encoding works by taking an existing JPEG stream produced by libjpeg(-turbo) and re-packaging it into a JPEG-XL stream. JPEG does not guarantee bit reproducible results and the Brunsli library is at version 0.1 so I think it is reasonable to expect slight differences in the output, which the imagecodecs tests currently do not account for. Just ignore the failure for now or disable the JPEG-XL codec.
As for your patch, the setup.py file currently supports conda-forge, recent Debian/WSL, the imagecodecs CI build system, and my development setup. On other platforms, either patch setup.py or customize the defaults providing your own imagecodecs_distributor_setup.customize_build function:

I enable snappy in blosc with -DDEACTIVATE_SNAPPY=OFF and disable jpeg-xl codec, the build is now successful.
