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


#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


#3

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


#4

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:


#7

NDK r15 is out now too and fixes this issue.
