Use zlib-ng

Open t20100 opened this issue 2 years ago • 2 comments

Following addition of blosc2 (PR #201), blosc2 and others are using zlib.

Yet, Blosc2 can use zlib-ng (sources included in internal-complibs/), and it should also be possible to use zlib-ng as a replacement for zlib for other filters too.

This is need to look at how zlib-ng handles building with SIMD instructions.

This already seems to be the case?

It'a currently using zlib (embedded in cblosc v1), not zlib-ng (embedded in cblosc v2).
