Compiling on M1 Macbook

Hi,

I’ve recently started Lazy Foo’s SDL tutorial and get the following errors when trying compile my test program. I’m on a M1 chip Macbook and suspect it has to do with that since many of the errors mention replacing ia32 with arm. As I’m new to SDL I’m not sure how to fix this on my end.

I’ve copied SDL2.framework into /Library/Frameworks and I’ve been compiling with g++ -l SDL2 test.cpp. Any guidance is appreciated!

My guess is that existing SDL headers will try to include mmintrin.h which will not work on ARM CPUs. This might be true in the existing prebuilt frameworks…?

Small update, I’m not too familiar with what I did exactly but building SDL from the source code instead of using the prebuilt framework fixed the issue. Thanks!
