I use cocos2d-x to develop a game, after it runs perfectly in iOs, I turn around to android platform.
But it run somewhere in android, and I only receive some error log like this:
08-26 10:49:23.823: A/libc(2884): Fatal signal 11 (SIGSEGV) at 0x0000000c (code=1), thread 2917 (Thread-285)
With this, I can't fix the crash log.
So my question is how can I check the stack of crash log?
And in SO, there are some similar questions, but with none useful answer to me.
Using ndk-stack to read crash logs
I find the perfect answer in http://www.cocos2d-x.org/boards/6/topics/20437.
The solution is:
When you get errors like this on the LogCat, they are saved on $PROJECT_PATH/obj/local/armeabi where $PROJECT_PATH is the path to your cocos2d-x android project. To symbolicate the messages to something understandable, you can use the ndk-stack tool.
Open up the Terminal (or Cygwin, not sure though) and type in
cd $ANDROID_NDK
adb logcat | ./ndk-stack -sym $PROJECT_PATH/obj/local/armeabi
where:
$ANDROID_NDK is the path to your android NDK
$PROJECT_PATH is the path to your cocos2d-x android project
And I try it, and get the following stack-trace:
