Enable building against an alternate Bzip2 and library
|

installation.
|

|

--with-libarchive=<path to libarchive installation tree> (Default: System)
|
||||
Enable building against an alternate libarchive installation.
|
||||
|
||||
NOTE:
|
||||
Pcompress only uses basic Libarchive functionality of
|
||||
creating PAX archives. No other functionality or filter
|
||||
support is used. So a local static libarchive build with
|
||||
most features disabled can be used with this option.
|
||||
|
||||
--no-sse-detect Do not try to detect the CPU's SSE capability. This
|
||||
mode will simply use SSE2 as the fallback default.
|
||||
Using SSE4 and later improves performance significantly.
|
||||
|
||||
--no-1.3-archive-compat Disable compatibility with compressed archives created with Pcompress
|
||||
version 1.3 (default: retain compatibility). Hash formats changed from
|
||||
version 1.3 to 1.4 so this option is required if files created using
|
||||
1.3 need to be decompressed by version 1.4 onwards.
|
||||
|

--use-key256 Use 256-bit encryption keys. Default key length is

128-bit.
