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. ```text libgrrlib <- 2D/3D graphics library ├── libfat <- File I/O ├── libjpeg <- JPEG image processor ├── libpngu <- Wii wrapper for libpng │ └── libpng <- PNG image processor └── libfreetype <- TrueType font processor ``` ## Developing for the Wii Do not progress until you have installed and configured devkitPro. Guides are and assistance are available at 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: 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 ``` 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 ``` Since GRRLIB and libpngu are now installed into the porlibs folder, make sure you don't have any leftovers from previous installations. You will need to manually delete unneeded libraries in _devkitPro\libogc\lib\wii_ as well as include files in _devkitPro\libogc\include_ ## 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 1. Create a directory to hold the code (e.g. C:\grr) 2.

If we had chosen the GPL licence you would be +forced+ (legally required) to release your source code. But in the spirit of "free as in FREE" we have left you with the +option+ to release your source code. We do +request+ that you tell others about us by naming our library (GRRLIB) in the credits of your game/application. And, if you +choose+ to do that, we encourage you to use our logo to achieve it; You can find our logo here: C:\grr\docs\grrlib_logo.png and here:
