OpenIndiana Distribution

Hi,
I did some testing and managed it to compile (with some tweaks):

 wget https://github.com/facebook/zstd/archive/v1.1.2.tar.gz
 mv v1.1.2.tar.gz zstd-1.1.2.tar.gz
 tar xfv zstd-1.1.2.tar.gz
 cd zstd-1.1.2/

 export CC=gcc
 export CXX=g++

 sed -i 's#OpenBSD FreeBSD DragonFly NetBSD#OpenBSD FreeBSD DragonFly NetBSD SunOS#g' $(find . -type f -name Makefile)
 sed -i 's#/usr/local#/opt/SFW#g' $(find . -type f -name Makefile)

 pfexec gmake install

 cd contrib/pzstd
 pfexec gmake install

$ zstd -h
*** zstd command line interface 32-bits v1.1.2, by Yann Collet ***
Usage :
      zstd [args] [FILE(s)] [-o file]

FILE    : a filename
          with no FILE, or when FILE is - , read standard input
Arguments :
 -#     : # compression level (1-19, default:3) 
 -d     : decompression 
 -D file: use `file` as Dictionary 
 -o file: result stored into `file` (only if 1 input file) 
 -f     : overwrite output without prompting 
--rm    : remove source file(s) after successful de/compression 
 -k     : preserve source file(s) (default) 
 -h/-H  : display help/long help and exit

Advanced arguments :
 -V     : display Version number and exit
 -v     : verbose mode; specify multiple times to increase log level (default:2)
 -q     : suppress warnings; specify twice to suppress errors too
 -c     : force write to standard output, even if it is the console
 -r     : operate recursively on directories
--ultra : enable levels beyond 19, up to 22 (requires more memory)
--no-dictID : don't write dictID into header (dictionary compression)
--[no-]check : integrity check (default:enabled)
--test  : test compressed file integrity 
--[no-]sparse : sparse mode (default:enabled on file, disabled on stdout)
 -M#    : Set a memory usage limit for decompression 
--      : All arguments after "--" are treated as files 

Dictionary builder :
--train ## : create a dictionary from a training set of files 
 -o file : `file` is dictionary name (default: dictionary) 
--maxdict ## : limit dictionary to specified size (default : 112640) 
 -s#    : dictionary selectivity level (default: 9)
--dictID ## : force dictionary ID to specified value (default: random)

Benchmark arguments :
 -b#    : benchmark file(s), using # compression level (default : 1) 
 -e#    : test all compression levels from -bX to # (default: 1)
 -i#    : minimum evaluation time in seconds (default : 3s)
 -B#    : cut file into independent blocks of size # (default: no block)

$ pzstd -h
Usage:
  pzstd [args] [FILE(s)]
Parallel ZSTD options:
  -p, --processes   #    : number of threads to use for (de)compression (default:4)
ZSTD options:
  -#                     : # compression level (1-19, default:3)
  -d, --decompress       : decompression
  -o                file : result stored into `file` (only if 1 input file)
  -f, --force            : overwrite output without prompting
      --rm               : remove source file(s) after successful (de)compression
  -k, --keep             : preserve source file(s) (default)
  -h, --help             : display help and exit
  -V, --version          : display version number and exit
  -v, --verbose          : verbose mode; specify multiple times to increase log level (default:2)
  -q, --quiet            : suppress warnings; specify twice to suppress errors too
  -c, --stdout           : force write to standard output, even if it is the console
  -r                     : operate recursively on directories
      --ultra            : enable levels beyond 19, up to 22 (requires more memory)
  -C, --check            : integrity check (default)
      --no-check         : no integrity check
  -t, --test             : test compressed file integrity
  --                     : all arguments after "--" are treated as files
