使用Android NDK生成的本机可执行文件与使用Raspbian的gcc-arm为Rasberry Pi生成的本机可执行文件有何不同（pi工具）

Question

I recently built a simple Hello World program using NDK and tried it to run on my Rasberry Pi2 running Rasberry Linux distribution on a Arm processor. But, the OS could not recognize the executable and complained it not to be a valid executable.

I am wondering why this is the case? Why do we have a different build tool chain for Android and Raspberry even though both are Linux and ARM.

Answer 1

Android uses armeabi or armeabi-v7a. On the other hand, Raspberry uses an incompatible gnueabihf ABI. Note that Android has Bionic runtime library, which is not exactly compatible with rest of Linux.
