Basic Installation
==================
@ -103,15 +101,30 @@ is not the usual GNU Autoconf script.
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.

Additional compilation flags can be passed to make like this:
make EXTRA_CPPFLAGS=<...> EXTRA_LDFLAGS=<...>
