Requirements

  • Classdef support
    • Octave >= 4.0
    • Matlab >= R2012b? (dunno when classdef was introduced...)
  • C-Compiler
  • hiredis library
  • Linux or Mac OS X (never tried with Windows)

Build instructions

  1. install a C compiler

    • Ubuntu: sudo apt-get install build-essential
    • Arch: sudo pacman -S base-devel
    • Mac: Install xcode

  2. install hiredis library

    • Ubuntu: sudo apt-get install libhiredis-dev libhiredis0.10 *for 14.04 LTS
    • Arch: sudo pacman -S hiredis
    • Mac: brew install hiredis

  3. mex.h

    • Distributed with your Matlab or GNU Octave installation

  4. clone/download and build go-redis directly from Matlab/GNU Octave

     >> cd go-redis/mex
 >> setup
 >> % go where ever you want and just do "addpath ('go-redis/inst')"

The default path to hiredis is set to /usr/include/hiredis. You can change it by set a variable LIBPATH with a absolute path to hiredis before running the setup script.

  1. optional - run tests

The mex folder contains a test_redis.m script with many assert() checks.

    >> test_redis
    This test will delete all databases of your redis instance on 127.0.0.1 6379.
    To continue type "YES": YES
    
        everything passed
    >>

Manually Matlab Instruction

You can compile it directly in the Matlab commandline.

mex -lhiredis -I/usr/include/hiredis/ CFLAGS='-fPIC -O2 -pedantic -std=c++11 -g' redis_.cpp

Afterwards mv redis_.mex* from mex folder into inst/private folder.

Manually GNU Octave Instruction

From GNU Octave commandline

mkoctfile -lhiredis -I/usr/include/hiredis --mex -fPIC -O2 -pedantic -std=c++11 -g redis_.cpp

Afterwards mv redis_.mex from mex folder into inst/private folder.

Currently (3/19/2015) there is a bug in classdef. You have to do addpath private in octave as a workaround! https://savannah.gnu.org/bugs/?41723

Manually Bash Instruction

You can compile it in bash too

gcc -fPIC -I <PATH TO mex.h> -lm -I <PATH TO hiredis.h> -lhiredis -shared -O2 redis_.cpp -o redis_.mex

e.g.

gcc -fPIC -std=c++11 -I /usr/include/octave-4.0.0/octave/ -lm -I /usr/include/hiredis/ -lhiredis -shared -O2 -pedantic redis_.cpp -o redis_.mex
