<options> can be one of the following: <options> can be one of the following:
--prefix=<val> The installation prefix. <options> can be one of the following:
This is set to /usr by default. However alternate
prefix needs to eb used during packaging.
--enable-debug Enable debug mode compilation. --prefix=<val> The installation prefix (default: /usr).
This reduces the compiler optimization level to
basic and taks out all the loop optimization flags.
This is primarily to aid debugging.
--disable-allocator Disable use of internal memory allocator mechanism. --enable-debug Enable debug mode compilation (default: disabled).
The internal allocator can be totally disabled by
setting this build time flag. It is also possible
to dynamically disable the allocator by setting the
following env variable:
ALLOCATOR_BYPASS=1
--enable-debug-stats Enable printing of some verbose debug info. --disable-allocator Disable use of internal memory allocator mechanism (default: enabled).
This at present shows some info related to Dedupe
efficiency. --enable-debug-stats Enable printing of some verbose debug info (default: disabled).
--with-openssl=<path to OpenSSL installation tree> (Default: System)
This defaults to the system's OpenSSL library. You can use this option
if you want to use an alternate OpenSSL installation.
--with-zlib=<path to zlib installation tree> (Default: System) --with-zlib=<path to zlib installation tree> (Default: System)
Enable building against an alternate Zlib installation. Enable building against an alternate Zlib installation.
--with-bzlib=<path to Bzip2 library installation tree> (Default: System) --with-bzlib=<path to Bzip2 library installation tree> (Default: System)
Enable building against an alternate Bzip2 and library 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.
--with-external-libbsc=<path to libbsc source tree> --with-external-libbsc=<path to libbsc source tree>
Enable building with exernal libbsc sources. In the LGPL licensed Enable building with exernal libbsc sources. Can be used to link with

MPLv2 licensed sources. So libbsc has to be downloaded separately
from: http://libbsc.com/ and linked into Pcompress using this option.
The current libbsc sources are licensed with ASLv2.
--no-sse-detect Do not try to detect the CPU's SSE capability. This --wavpack-dir=<path to WavPack source tree>
mode will simply use SSE2 as the fallback default. Points to the directory containing the WavPack sources. This option
Using SSE4 and later improves performance significantly. must be specified if --disable-wavpack is not provided.
--disable-wavpack Disables the WavPack filter.
--no-sse-detect Do NOT attempt to probe the system's SSE capability for build flags.

--no-avx-detect Do NOT attempt to probe the system's AVX capability for build flags.
