Hello,
I'm trying to debug native code in a shared library but I am having some issues with 'No source available for "class::function() at 0x00000000" ' errors, and I can not get a stack trace when using bt in the gdb console. I'm using ADT v22 and the NDK plugin. For my setup I have a C++ Project projA which contains a set of static libraries, my main project projB, and a native C++ project libA. Now, libA adds the static libraries from projA into it's .so with an Android.mk\ like this:
And projB adds the libA.so with an Android/.mk like this:

LOCAL_CFLAGS += -I$(PROJECT_INCLUDES)

And projB adds the libA.so with an Android/.mk like this:
include $(CLEAR_VARS)
LOCAL_MODULE := STEP_Wrapper-prebuilt
LOCAL_SRC_FILES := ../libA/obj/local/armeabi/libstepwrapper.so
include $(PREBUILT_SHARED_LIBRARY)
I ran the nm command on the .o's contained in projA's static libraries and it looks like the debugging symbols are present. I also ran file on libA.so and it says it's non-stripped. Is there something else I'm missing so I can properly debug my native code?LOCAL_MODULE := STEP_Wrapper-prebuilt

I meant that I ran the nm command on the static libraries and it looks like the debugging symbols are present. And I also ran file on the .o's from the static libraries and libA.so and it says it's non-stripped.

I'm
not sure, I'm executing native debugging through Eclipse, not the
command line. I right click my project and hit "Debug as -> Android
Native Application". This is the message I get in the CDT Global Build
Console in Eclipse:

What is the ndk-gdb command you are using? It's tricky to point it to the correct place. And even then, I find it more miss than hit, esp. after a crash.

Anyone have a general idea of how to debug native libraries? If someone needs more info please tell me.

Hi,
If you have AndroidManifest.xml which caontains android:debuggable="true" and you have built your project with NDK_DEBUG=1 then in principle you should be able to run ndk-gdb.
What is the output when you run ndk-gdb from the directory where the jni sub-directory is located?

I'm hoping to get this working under Eclipse with the NDK plugin though. The error I got then is in a previous post in case it helps.

Well, I tried to make Eclipse working with ndk-gdb but it does not work out of the box as it is a script and Eclipse assumes talking to the gdb directly.
I can debug in Eclipse using ARM EABI gdb on a rooted device with a gdbserver started on the device and attached to the process I want to debug.
It seems you can debug with ndk-gdb now using command line though.
What you need also is to configure gdb.setup or .gdbinit to let know gdb where are the non-stripped versions of the libraries, something like:
set solib-search-path ./obj/local/armeabi
directory /path/to/the/ndk8d/platforms/android-8/arch-arm/usr/include jni/armeabi /path/to/the/ndk8d/sources/cxx-stl/system
file ./obj/local/armeabi-v7a/app_process
target remote :5039
also make sure you have your non-stripped libraries linked or copied into the directory mentioned above ./obj/local/armeabi .
Hope this helps

I noticed in the obj/local/armeabi directory there is a gdb.setup file which I used to configure gdb on the command line. The gdb.setup file contains:

The libs are stripped... So you either need to use the unstripped version in $(OUT)/obj/... Or add the cflags -g to your modules.
You'll still need to point gdb to the source code directory and connect everything to gdb-server.

I saw that message also about app_process having no debugging symbols. I am using the .so found in libA's /obj directory. Where should I add the -g flag though, if libA's Android.mk or in projB's?

You can see how I'm including the headers on the path and how I'm grabbing the static libraries to add to the shared library. I was looking at the ndk/docs/PREBUILTS and various forum threads and I noticed that there were suggestions to use LOCAL_C_INCLUDES instead of LOCAL_CFLAGS because the former let gdb know about the library's header paths. I also heard using LOCAL_EXPORT_C_INCLUDES would allow my projB, who's make file I already posted, to add those header files to the search path too. But when I do use them, and not the LOCAL_CFLAGS, I get errors that so and so header couldn't be found.LOCAL_SRC_FILES := $(FILE_LIST:$(LOCAL_PATH)/%=%)
