How to let cocos2dx eclipse android project
to set breakpoint to in eclipse windows platform?
I only can use log to print, but it is hard to debug.

Set breakpoint in your C++ class
Select project ~~> Right Click~~> Debug as ->Android native application.

*Note: Make sure you have setup correct NDK path in Android Preferences in Eclipse.

I already add native support.

My project setting is use Eclipse Builders to run
C:-ndk-r8e\ndk-build.cmd to build source code,
I don’t have add any C++ source code into Eclipse Project,
it use Android.mk to set LOCAL_SRC_FILES := hellocpp/main.cpp …/…/Classes/AppDelegate.cpp …/…/Classes/GameData.cpp Cocos2dx source code and My Classes folder is not in proj.android folder.
If I want to debug AppDelegate.cpp or cocos2dx source code, how to add this source code into Eclipse project.

And my main.cpp show many error about unresolved inclusion.

First you need to resolve errors related to Includes.

Go to Project properties -> C/C++ General -> Path and symbols -> Includes -> Add
then add paths like

E:/cocos2dx/cocos2d-x-2.1.5/cocos2dx/include E:/cocos2dx/cocos2d-x-2.1.5/extensions E:/cocos2dx/cocos2d-x-2.1.5/cocos2dx

This will resolves all issues related to include. And also disable Syntax and semantic errors
from C/C++ General -> Code Analysis -> Un-check Syntax and Semantic Errors

If you want to add Classes to your eclipse workspace then just create a folder and in advanced option link it to your classes folder.

Clean your project and go to Project -> Properties -> C/C++ Build -> Builder Settings
Now change Build command : ndk-build.cmd NDK_DEBUG=1 APP_ABI=armeabi

Here you need to set correct CPU architecture for APP_ABI. If you are using an Intel based device then you can set APP_ABI=x86 etc.

Hope this will help you.

I can run debug now,
I set breakpoint
But the call stack is only
XXXProject (1) [Android Native Application]
app_process
gdb
and have a gdb error below:

warning: Could not load shared library symbols for 77 libraries, e.g. /system/bin/linker.
Use the “info sharedlibrary” command to see the complete listing.
Do you need “set solib-search-path” or “set sysroot”?
warning: Unable to find dynamic linker breakpoint function.
GDB will retry eventurally. Meanwhile, it is likely
that GDB is unable to debug shared library initializers
or resolve pending breakpoints after dlopen().

yayaigo · October 15, 2013, 12:32pm

Anybody know how to fix the warning?
Maybe this warning cause my breakpoint is not avalible.
