 1 | # Cross Compile on Mac OSX for mruby
 2 | Cross compile osx, linux or win32 binary of mruby on Mac OSX.
 3 | 
 4 | ## Donwload and install by mrbgems
 5 | ### Donwload mrbgem
 6 | ```
 7 | git clone https://github.com/matsumoto-r/mruby-cross-compile-on-mac-osx.git
 8 | ```
 9 | 
10 | ### add conf.gem line to `build_config.rb`
11 | ```ruby
12 | MRuby::Build.new do |conf|
13 | 
14 |   # ... (snip) ...
15 | 
16 |   # the last line of conf.gem
17 |   load '/path/to/mruby-cross-compile-on-mac-osx/mrbgem.rake'
18 | end
19 | ```
20 | 
21 | ### Download and Install Cross Compiler on Mac OSX
22 | - [Cross Compiling for Win32 on MacOS X](http://crossgcc.rts-software.org/doku.php?id=compiling_for_win32)
23 | - [Cross Compiling for Linux 32 and Linux 64 on MacOS X](http://crossgcc.rts-software.org/doku.php?id=compiling_for_linux)
24 | 
25 | ### Cross Compile with MRUBY_CROSS_OS Env
26 | #### for linux
27 | ```
28 | rake MRUBY_CROSS_OS=linux
29 | ```
30 | #### for osx
31 | ```
32 | rake MRUBY_CROSS_OS=osx
33 | ```
34 | #### for win32
35 | ```
36 | rake MRUBY_CROSS_OS=win32
37 | ```
38 | 
39 | then, generate mruby binaries into `mruby/build/{linux,osx,win32}/`
