Unable to see local variables when debugging (NDK r9, x86 emulator)

[folecr]

I'm using the NDK r9 on the x86 emulator (Android 16 system image)

I'm able to step through my C++ source code in a full debug build. I am NOT able to see any local variables. gdb does not find them. "info locals" shows one single static variable (defined in the file that holds the function I hit the breakpoint on.)

Has anybody encountered this? How do I get past this and actually print the contents of local variables?

I've tried all kinds of things - removing the strip command completely, removing the release flags from the command line (even though these flags are reset by the debug flags) My remaining option is to move to an older version of the NDK because I *was* able to debug a few months ago...

Thanks.

Ah! The problem seems to be with GCC 4.8 and the DWARF4.

Jonathan Wakely's post here was helpful in diagnosing the problem : http://stackoverflow.com/questions/12595631/debugging-with-gdb-on-a-program-with-no-optimization-but-still-there-is-no-symbo

Adding -gdwarf-2 seems to allow me to see local variables

Hello, could you elebrate how did you add -gdwarf-2 to the NDK build? Thanks!

Thanks dude, It works.
I was encountering this problem right after switching GCC 4.6 to 4.8.
