Title: Problems with linking SDL2
Post by: WhyAmIDoingThis on December 30, 2024, 08:44:24 pm

I want to learn more about SDL2. I tried creating project the DLS2 project in code blocks and i followed this https://lazyfoo.net/tutorials/SDL/01_hello_SDL/windows/codeblocks/index.php (https://lazyfoo.net/tutorials/SDL/01_hello_SDL/windows/codeblocks/index.php). I am on windows 10 using code blocks 20.03 and using min-gw. I have adjusted search directories in the project build options of both the compiler and the linker. But I am still getting a linker error. Please help.
My build log is:

Mixing an 32 bit library and a 64 bit toolchain is not likely to work!

Step 1. Decide if you wish to use 32 bit or 64 bit?
Step 2. If 64 bit, find or build an 64 bit SDL2 libraries.
            If 32 bit, find an 32 bit GCC toolchain to use; and, configure CB to use it.

Edit: x86 means 32 bit; x64 means 64 bit.
Edit2: https://github.com/libsdl-org/SDL/releases (https://github.com/libsdl-org/SDL/releases)
Edit3: x86_64 means 64 bit, also.
Edit4: i686 means 32 bit, also
