Greg Tucker 1ba280fa09 igzip: Fix and clarify a few code issues in the cli tool 
Fixes a few scan build hits. A few are false positives such as a missed free but
better to clarify the code in this case. Others such as calling no-null
functions are made explicit.

Intel(R) Intelligent Storage Acceleration Library

Build Status

ISA-L is a collection of optimized low-level functions targeting storage applications. ISA-L includes:

  • Erasure codes - Fast block Reed-Solomon type erasure codes for any encode/decode matrix in GF(2^8).
  • CRC - Fast implementations of cyclic redundancy check. Six different polynomials supported.
    • iscsi32, ieee32, t10dif, ecma64, iso64, jones64.
  • Raid - calculate and operate on XOR and P+Q parity found in common RAID implementations.
  • Compression - Fast deflate-compatible data compression.
  • De-compression - Fast inflate-compatible data compression.

Building ISA-L

Prerequisites

  • Assembler: nasm v2.11.01 or later (nasm v2.13 or better suggested for building in AVX512 support) or yasm version 1.2.0 or later.
  • Compiler: gcc, clang, icc or VC compiler.
  • Make: GNU 'make' or 'nmake' (Windows).
  • Optional: Building with autotools requires autoconf/automake packages.

Autotools

To build and install the library with autotools it is usually sufficient to run:

./autogen.sh
./configure
make
sudo make install

Makefile

To use a standard makefile run:

make -f Makefile.unx

Windows

On Windows use nmake to build dll and static lib:

nmake -f Makefile.nmake

Other make targets

Other targets include:

  • make check : create and run tests
  • make tests : create additional unit tests
  • make perfs : create included performance tests
  • make ex : build examples
  • make other : build other utilities such as compression file tests
  • make doc : build API manual
