## Introduction
|
|
|
|
GRRLIB is a C/C++ 2D/3D graphics library for Wii application developers. It is
|
|
essentially a wrapper which presents a friendly interface to the Nintendo GX
|
|
core.
|
|
|
|
GRRLIB is supplied as a standard C/C++ library (aka. archive)
|
|
called 'libgrrlib'. Because GRRLIB processes JPEG and PNG images, it requires
|
|
the installation of the 'libjpeg' and 'libpngu' libraries. 'libpngu', in turn,
|
|
requires 'libpng'. GRRLIB has FileIO functions
|
|
to allow real-time loading and saving of graphical data, and thus requires
|
|
'libfat'. GRRLIB also has the possibility to use TrueType fonts, so
|
|
'libfreetype' is also required.
|
|
|
|

|

```
|
|
|
|
## Developing for the Wii
|
|
|
|
Do not progress until you have installed and configured devkitPro. Guides are
|
|
and assistance are available at <https://devkitpro.org/index.php>
|
|
|
|
If you have just performed a clean (re)install on your Windows PC, be sure to
|
|
reboot before you continue.
|
|
|
|
## Downloading GRRLIB
|
|
|
|
You are invited to use "the latest Git master version" of GRRLIB at all times.
|
|
|
|
The Git repository is located at: <https://github.com/GRRLIB/GRRLIB>
|
|
|
|
There is a simple guide to "Using GitHub" later in this document.
|
|
|
|
This document will presume that you have downloaded "the latest Git master
|
|
version" to a directory called C:\grr
|
|
|
|
## Installing GRRLIB
|
|
|
|
This guide is for Windows. If you are using Linux, I am going to presume you
|
|
are smart enough to convert these instructions.
|
|
```text
|
|
GRRLIB is supplied as source code
|
|
libpngu is supplied as source code
|
|
libpng is supplied via devkitPro pacman (ppc-libpng)
|
|
libfreetype is supplied via devkitPro pacman (ppc-freetype)
|
|
libjpeg is supplied via devkitPro pacman (ppc-libjpeg-turbo)
|
|
libfat is supplied via devkitPro pacman (libfat-ogc)
|
|
```
|
|
|
|
The easy way is to install GRRLIB and all the required libraries in a single
|
|
command:
|
|
```bash
|
|
c:
|
|
cd \grr\GRRLIB
|
|
pacman --sync --needed --noconfirm libfat-ogc ppc-libpng ppc-freetype ppc-libjpeg-turbo
|
|
make clean all install
|
|
```
|
|
|
|
This process may take some time depending on the speed of your PC.
|
|
|
|
If you used the method above the following steps are not required, GRRLIB is
|
|
installed and you are ready to start developing Wii homebrew games.
|
|
|
|
If you want, you could install the libfat, libpng,
|
|
libfreetype and libjpeg with there dependencies in a single command:
|
|
```bash
|
|
pacman --sync --needed --noconfirm libfat-ogc ppc-libpng ppc-freetype ppc-libjpeg-turbo
|
|
```
|
|
|
|
Each library could also be installed individually:
|
|
|
|
To install libpngu
|
|
```bash
|
|
c:
|
|
cd \grr\GRRLIB\lib\pngu
|
|
make clean all install
|
|
```
|
|
|
|
To install libgrrlib:
|
|
```bash
|
|
c:
|
|
cd \grr\GRRLIB\GRRLIB
|
|
make clean all install
|
|
```
|
|
|
|
## Using GRRLIB
|
|
|
|
After everything is installed, simply put
|
|
```c
|
|
#include <grrlib.h>
|
|
```
|
|
at the top of your .c/.cpp file and use the functions as required
|
|
|
|
You will need to add
|
|
```make
|
|
-lgrrlib -lfreetype -lbz2 -lfat -ljpeg -lpngu -lpng -lz
|
|
```
|
|
to the libs line in your makefile
|
|
|
|
...Remember the order of the libraries is critical. You may (need to) insert
|
|
other libraries in the middle of the list, you may need to add others to the
|
|
start, or even the end - but do _not_ change the order of the libraries shown
|
|
here.
|
|
|
|
Also add $(PORTLIBS) to the LIBDIRS line in your makefile
|
|
|
|
You do NOT need to place /anything/ in your application directory.
|
|
|
|
If you would like to see a working example of this, you can look at the example
|
|
found in: C:\grr\examples\template\source
|
|
|
|
## Upgrading to v4.4.0 From Previous Versions of GRRLIB
|
|
|
|
This version now uses the ported libraries for the Wii.
|
|
|
|
To install them, use this command line:
|
|
|
|
```bash
|
|
pacman --sync --needed --noconfirm libfat-ogc ppc-libpng ppc-freetype ppc-libjpeg-turbo
|
|
```
|
|
|
|
You will need to add $(PORTLIBS) to the LIBDIRS line in your makefile.
|
|
|
|
Previously it could have looked like this:
|
|
|
|
```make
|
|
LIBDIRS :=
|
|
```
|
|
|
|
Now it needs to be like this:
|
|
|
|
```make
|
|
LIBDIRS := $(PORTLIBS)
|
|
```
|
|
|
|
The FreeType library is now compiled with a dependency on bzip2,
|
|
so lbz2 needs to be added after lfreetype in your makefile.
|
|
|
|
For example:
|
|
|
|
```make
|
|
LIBS := -lgrrlib -lfreetype -lbz2 -lpngu -lpng -ljpeg -lz -lfat
|
|
```
|
|
|
|
## Using GitHub
|
|
|
|
GitHub allows the developers to submit changes to the code in such a way that
|
|
these changes can be easily monitored, quickly merged together with other
|
|
changes. and (if necessary) reverted.
|
|
|
|
It also allows the power-users to gain access to the latest (often "in-test")
|
|
features.
|
|
|
|
To obtain the "cutting edge" codebase go to <https://github.com/GRRLIB/GRRLIB/tree/master>
|
|
|
|
1. Create a directory to hold the code (e.g. C:\grr)
|
|
2. Click the _Download ZIP_ button if you don't have the proper tools installed on your PC or Clone the following URL <https://github.com/GRRLIB/GRRLIB.git>
|
|
|
|
All official releases can be found here <https://github.com/GRRLIB/GRRLIB/releases>
