The official documentation can be found here.

Android Studio – Android Studio – linker error when updating gradle from 7.3.3 to 7.4

When I try to build my project, I get errors now. I didn’t change a thing and I was under the impression, that it did build a few years ago.
Can you please assist?

The error message is:

C/C++: ld: error: C:UsersgfDownloadsandroid-projectappbuildintermediatescxxDebug14s2b4rb/obj/local/arm64-v8a/objs-debug/main/glbasic/glb-full.o: unable to find library from dependent library specifier: SDL.lib

You can find the project at:
https://www.glbasic.com/beta/twintris_as.zip

** UPDATE **
I changed the project and it is building, now. However, once I upgrade from gardle 7.2.2 to 7.3.0 or higher, I get the linker errors.

    It appears as if you need to tell the compiler where to find the SDL libraries. You could follow the advice here: Linking errors with SDL_mixer library

    You want to make sure those lib libraries are in a place the compiler can find as well.

    I was able to compile your project by adding this line.
    Inside the ‘build.gradle’ file related to the ‘app’

    Inside the ‘externalNativeBuild’ scope Add this line like this:

    externalNativeBuild {
    ndkBuild {
        cppFlags += "-DGLB_CONSOLE"
        ...
    }
}
