Gdb debug the native (not jni) program on android

Question

I failed to debug the native program with NDK toolchain. Follows are my detailed steps and output.

Env Setting:

NDK_ROOT=/opt/android/ndk
SYSROOT=$NDK_RO         


        

Answer 1

I don't know why gdb works with the binary by ndk-build, but use file command instead of symbol-file command, it might work. gdb needs to know the image of the remote executed program.

(gdb) file hello
