Getting "Unable to open symbol file xxx. Error (9): Bad file descriptor" when using ndk-stack from NDK R6

[cmarkle]

Trying the new ndk-stack tool in NDK R6... When I run it I get "Unable
to open symbol file libs/armeabi/libfaspapijni.so. Error (9): Bad file
descriptor" on each line related to my libxxx.so file. As in:

$ cat out7 | /Users/xxx/Devel/android/android-ndk-r6/ndk-stack -sym
libs/armeabi

Stack frame #04 pc 00010dac /system/lib/libc.so

I tried both absolute an relative paths for the -sym argument and it
failed the same way for both cases.

libs/armeabi has the lib in it:

$ ls -l libs/armeabi/
total 6712
-rwxr-xr-x 1 xxx staff 3433724 Jul 26 09:35 libfaspapijni.so

and if I "strings" the lib, it's readable.

Any thoughts about what I might be doing wrong here? Thanks in
advance!

The error message is misleading. It really should say that it could not find any symbols in the library files

That's because you are pointing to libs/armeabi/ which contains +stripped+ binaries.

You should instead point to obj/local/armeabi/ which contains the same libraries with all symbols.

Hope this helps.

Actually, I get the same error even when pointing to obj/local:

> ndk-stack -sym ./obj/local/armeabi -dump stack-dump.txt

You are so right.... Thanks
