libSDL_image 1.2.12 repository for CASIO fx-CG 10/20 (a.k.a. PRIZM) and fx-CG 50 (or Graph 90+E)

Need to have a fully working gcc toolchain for SH3/SH4 architecture, such as fxSDK

Note: libSDL_image is configured to support PNG, so you need to have :

• a working libPNG, see here : libPNG for PRIZM,
• and also requires Zlib available, so the very first step is to get these libraries available and working prior to libPNG. You can get a working Zlib for CASIO fx-CG 10/20 (a.k.a. PRIZM) and fx-CG 50 (or Graph 90+E) here : libZlib for PRIZM.
• and a working copy of SDL 1.2 that you can get here : libSDL for PRIZM

Automatic installation using giteapc

You can also use the gitea install Slyvtt/cSDL_image1_2_12 command to get an automatic install

when you compile a program for use with libSDL_image, do not forget to add a -lSDL_image_prizm -lcPNG -lczlib -lSDL_prizm option in your compilator command line.

and then a #include <SDL/SDL_image.h> in your C/C++ sources

Manual compilation using a Makefile

Compilation is done by using the adhoc Makefile : make -f Makefile.prizm in the main directory

It should produce the library libSDL_image_prizm.a and copy everything in the right place.

The following steps are not automatically done, so please proceed with the following manipulations :

• copy the library libSDL_image_prizm.a into your SH3/SH4 compiler lib folder
• copy SDL_image.h file contained in the SDL/ folder into the include/SDL folder of the SH3/SH4 compiler
