Introduction
|
||||
------------
|
||||
|
||||
GRRLIB is a C/C++ 2D Graphics library for Wii application developers. It is
|
||||
essentially a wrapper which presents a friendly interface to the Nintendo GX
|
||||
core.
|
||||
|
||||
As of v4.10., 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' and 'libpng' requires 'libz'.
|
||||
|
||||
libgrrlib <- 2D graphics library
|
||||
+-- libjpeg <- JPEG image processor
|
||||
+-- libpngu <- Wii wrapper for libpng
|
||||
+-- libpng <- PNG image processor
|
||||
+-- libz <- Zip (lossless) compsression (for PNG compression)
|
||||
|
||||
|
||||
Developing for the Wii
|
||||
----------------------
|
||||
|
||||
Do not progress until you have installed and configured devkitPro. Guides are
|
||||
and assistance are available at http://forums.devkitpro.org
|
||||
|
||||
If you have just performed a clean (re)install on your Windows PC, be sure to
|
||||
reboot before you continue.
|
||||
|
||||
|
||||
Downloading GRRLIB
|
||||
------------------
|
||||
|
||||
You are advised to use "the latest SVN trunk version" of GRRLIB at all times.
|
||||
There is a simple guide to "Using SVN" here:
|
||||
http://grrlib.santo.fr/forum/viewtopic.php?id=182
|
||||
|
||||
This document will presume that you have downloaded "the latest SVN trunk
|
||||
version" to a directory called C:\grr\trunk
|
||||
|
||||
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.
|
||||
|
||||
GRRLIB is supplied as source code.
|
||||
libjpeg is supplied as a precompiled library.*
|
||||
libpngu is supplied as source code
|
||||
libpng is supplied as a precompiled library
|
||||
libz is supplied with devkitpro (Ie. preinstalled)
|
||||
|
||||
*The version of libjpeg supplied with GRRLIB v4.1.0 contains bug fixes not
|
||||
available in the official release. If you can track down the original author,
|
||||
please tell him about these fixes.
|
||||
|
||||
Because of the way dependancies work, the libraries must be installed in reverse
|
||||
order.
|
||||
|
||||
libz comes preinstalled with devkitPro, so we can move directly to libpng...
|
||||
|
||||
To install libpng
|
||||
c:
|
||||
cd \grr\trunk\GRRLIB\lib\png
|
||||
make install
|
||||
|
||||
Next up the list is libpngu
|
||||
c:
|
||||
cd \grr\trunk\GRRLIB\lib\pngu
|
||||
make clean
|
||||
make all
|
||||
make install
|
||||
|
||||
Next up the list is libjpeg*
|
||||
c:
|
||||
cd \grr\trunk\GRRLIB\lib\jpeg
|
||||
make install
|
||||
|
||||
*The version of libjpeg supplied with GRRLIB v4.1.0 contains bug fixes not
|
||||
available in the official release.
|
||||
|
||||
Finally, we can now install libgrrlib
|
||||
c:
|
||||
cd \grr\trunk\GRRLIB\GRRLIB
|
||||
make clean
|
||||
make all
|
||||
make install
|
||||
|
||||
|
||||
Using GRRLIB
|
||||
------------
|
||||
|
||||
After everything is installed, simply put
|
||||
#include <grrlib.h>
|
||||
at the top of your .c file and use the functions as required
|
||||
|
||||
You will also need to add
|
||||
-lgrrlib -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.
|
||||
|
||||
You do NOT need to placce /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\trunk\examples\bluechip\composition
|
||||
...This example also includes a "Makefile" which tries to make it clear what is
|
||||
happening (unlike the more comprehensive cross-platform Makefile supplied with
|
||||
the devkitPro template application).
|
||||
|
||||
|
||||
Error: guVector redefined
|
||||
-------------------------
|
||||
|
||||
If you get this error, you are probably using a version of libogc more recent
|
||||
than the released v1.7.1a.
|
||||
|
||||
In the libogc SVN revision 3650 Vector was renamed to guVector "to avoid
|
||||
collisions" ...also Quaternion was renamed to guQuaternion - but GRRLIB does
|
||||
not use these!
|
||||
|
||||
The main codebase of GRRLIB has been updated to reflect this change.
|
||||
But until the new libogc is officially released, if you are using a version of
|
||||
libogc later than v1.7.1a/svn3649, you will need to add:
|
||||
-DNOGUFIX
|
||||
to the compiler flags (CFLAGS) in your makefile
|
||||
|
||||
When the libogc changes are officially released, this *temporary fix* should be
|
||||
removed [see grrlib.h, line 50ish]
|
||||
The requirement for -DNOGUFIX will be deprecated, but its lingering presence
|
||||
will not be a hinderance
|
||||
|
||||
Thanks to Nicksasa for reporting this problem
