# libarchive Decompression Backend
|
|
|
|
This backend utilizes the [libarchive](https://www.libarchive.org/) library to support a wide
|
|
variety of compression formats.
|
|
|
|
This backend is currently only supported on the Linux platform.
|
|
|
|
## Using
|
|
|
|
Enable this backend by setting the `DECOMPRESSION_BACKEND` CMake option:
|
|
|
|
cmake -B build -DDECOMPRESSION_BACKEND=libarchive
|
|
|
|
Upon success, the application can be built as normal.
|
|
|
|
## Limitations
|
|
|
|
* libarchive has a stream-based architecture that does not (currently) offer random access.
|
|
In practice, this means that you can only seek forward and would have to re-open an archive
|
|
to read an entry before the current position. This doesn't seem to have a huge performance
|
|
hit and can be mitigated by creating properly sorted archives.
|
|
* 7z decompression is slow (but seems to be slightly faster than unarr)
