How can i add SDL lib to my dev C++

i dont know how can to fix it, if u know this, pls help me to add the lib

I think this is more a general C++/IDE question rather than an SDL one. You need to add an include directory to your project or else the IDE won’t know where to find the headers. I don’t use Dev C++ but perhaps you can follow this tutorial: How to add library files in Dev C++ - Quora

Oh, thank you so much
