Hi All,
What is the expected behavior when running an executable built with
the NDK and compiled with Position Independent Code (PIE) on a device
running Android < 4.1?
I've experienced a crash on 3 different test devices from
/system/bin/linker. Below is from Android 4.0.3 (ASUS TF-101A). Its
nearly identical to the crash on my other 4.0.3 device (HTC EVO 4G).
Is there a way to build a single executable with PIE for both Android
4.0.3 (and below) and Android 4.1 (and above)?
Jeff
