Incapable of decompressing LZMA or LZMA2 created from default 7Zip settings

[disassembledd]

As the title implies. This is repeatable by creating any file, zipping it with 7Zip defaults with LZMA or LZMA2, and testing lzma_decompress or lzma2_decompress. The former results in a "distance X is beyond output size Y" error, the latter results in a "invalid status 55" error.

Similar problem here: I have tried to compress a file using the lzma -9 -z <file> command, unfortunately the library seems to be unable to decode the lzma file.

LzmaError("LZMA2 invalid status 93, must be 0, 1, 2 or >= 128")

Edit: I also tried with xz -9 <file> it also didn't work

have you found a way to detect those decompressable-with-7z-only files? I'd be fine with using 7z as an escape hatch I guess, but it's really hard to deduce which files are 7z-only and which are not

I think in my case I was using LZMA 1 (using the lzma command) instead of LZMA 2 (xz). I didn't test it further, instead I used liblzma which is based on the C xz library.

Maybe providing an example how to compress files to be extracted by this library could reduce confusion.

edit: My fault, i didn't read :)

I'm trying to use "zip2" library to extract files and this started happening suddenly
