I've been trying to use LibVLC for Android and I followed the instructions at https://wiki.videolan.org/AndroidCompile and got it to work perfectly for ARM. However, when trying to compile it to x86, I set:
export ANDROID_ABI=x86
and then compiled in the same way, but now I have a problem as it fails to compile. Here's a truncated build log:
~/vlc-android$ sh compile.sh

As far as I can tell, in that project for some reason both the ARM headers and the SSE headers are being included, causing a redefinition error. However, I don't know why or what to try to fix it. Any suggestions would be much appreciated.
