Description Evangelos Foutras 2014-08-30 08:51:14 UTC

This is the error given by the lz4 command-line utility when trying to uncompress a core dump compressed with LZ4:

"Error 44 :Unrecognized header : file cannot be decoded".

Currently liblz4 doesn't seem to contain any facilities to generate proper .lz4 files. The solution to this might be the "Framing API" that is being worked on:

This has been implemented a while back.
