Building for android, getting error compiling SDL_wave.c Edit: errors on other steps randomly

Game Development
1

The build output is shown below.
Compiles and runs fine if I build it for mac.
(I’m on OSX El Capitan, 10.11.6)

I can give whatever other specs might help, but honestly I’m at a bit of a loss in coming up with what would be relevant…

Is this a bug in llvm?

Edit: if I try multiple times, it errors on different steps… I have the output for it failing on

[armeabi] Compile thumb  : SDL2 <= SDL_syshaptic.c
fatal error: error in backend: Cannot select: 0x7fb91418edc0: i32 = ARMISD::SSAT

as well as

[armeabi] Compile thumb  : SDL2 <= SDL_sysjoystick.c
fatal error: error in backend: Cannot select: 0x7fc2a4112fc0: i32 = ARMISD::SSAT

So, now I’m even more unsure what could possibly be happening…

Yes, this is a bug in llvm. You can change the compiler to gcc until this is fixed by editing your Application.mk and adding the line:

NDK_TOOLCHAIN_VERSION := 4.9

Oh goodness thank you so much! Was going crazy trying to make sense of this while lacking deep compiler knowledge. Thanks!

Do you happen to know how to fix this with Gradle when using CMake, like with the latest Android Studio projects?

5

I haven’t tried, but these docs https://developer.android.com/ndk/guides/cmake.html#variables suggest you can do:

externalNativeBuild {
      cmake {
            arguments "-DANDROID_TOOLCHAIN=gcc",
6

Download the latest NDK beta version it’s fixed in that (This is the issue: https://github.com/android-ndk/ndk/issues/361)

You can see my example project for a gradle example:

NDK r15 is out now too and fixes this issue.
