cSDL_image/README.md

Simple DirectMedia Layer SDL sublibrary SDL_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

You can use the giteapc install Slyvtt/cSDL_image command to get an automatic install

Using in a program

With CMake

find_package(cSDL_image 1.2.12 REQUIRED)
target_link_libraries(<TARGET> PRIVATE cSDL_image::cSDL_image)

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

• copy the library libcSDL_image.a into your SH3/SH4 compiler lib folder
• copy all header files *.h in the include folder include/SDL of the SH3/SH4 compiler
• link with -lcSDL_image

In the C/C++ sources #include <SDL/SDL_image.h>

Typical CMakeLists.txt

Below is the typical minimum CMakeLists.txt file to be used for a fxSDK project aiming at using the cSDL_image library :

find_package(cSDL 1.2.15 REQUIRED)
find_package(cSDL_image 1.2.12 REQUIRED)
