The Rosie Pattern Engine's installation script looks for the pre-requisites within the Rosie install directory, so that Rosie has its own copy of the pre-requisite software, such as Lua and lpeg.
The pre-requisites are:
| pre-req | description |
|---|---|
| lua | Lua binary (command line driver) |
| lpeg | Lua Parse Expression Grammars library |
| cjson | JSON encoding/decoding library |
Like Lua, the native libraries must be built for your particular
platform. The makefile included with Rosie will download and compile the
prerequisites, all within the Rosie install directory.
The tools needed to compile and install Rosie and its pre-requisites are commonly available on most systems.
The build instructions for Rosie are in its makefile, which uses cc (MacOSX)
or gcc (Linux) to compile the components needed by the Rosie Pattern Engine.
Those components (see table above) are downloaded automatically using curl.
| tool | description |
|---|---|
| make | processes makefile to build Rosie |
| cc | on MacOSX, the compiler that is part of Apple's developer tools |
| gcc | on Linux, the GNU C compiler that is most prevalent |
Note: You can override the choice of compiler on the command line, e.g. if you want to use gcc on MacOSX:
make CC=gcc macosx
