NDK分析显示＆QUOT;。所以没有符号＆QUOT; [英] NDK profiling showing ".so has no symbols"

问题描述

我做NDK分析了使用Android的NDK廓-3.1我的项目。我在Android.mk中所做的更改如下...

I am doing NDK profiling for my project using android-ndk-profiler-3.1. I have made changes in Android.mk as follows...

LOCAL_PATH := $(call my-dir)
 -include android-ndk-profiler.mk
include $(CLEAR_VARS)

# Module name -------------------------------------------------------
LOCAL_CFLAGS += -O3 
TARGET_ARCH_ABI :=armeabi
LOCAL_CFLAGS := -pg
LOCAL_STATIC_LIBRARIES := andprof
LOCAL_LDLIBS += -llog
LOCAL_MODULE := libitv

include $(BUILD_SHARED_LIBRARY)

Application.mk如下：......

Application.mk is as follows...

APP_ABI := armeabi
APP_PLATFORM := android-10

我呼吁monstartup（itv.so）;在本地code和moncleanup的开始（）函数;功能的停止方法。而且是gmon.out文件被创建successfully.And以后，我贴在是gmon.out
D:\\android\\android-ndk-r6-windows\\android-ndk-r6\\toolchains\\arm-linux-androideabi-4.4.3\\$p$pbuilt\\windows\\bin 。目录

I have called monstartup("itv.so"); function in the beginning of the native code and moncleanup(); function in the stop method. And gmon.out file is created successfully.And then I have pasted gmon.out in D:\android\android-ndk-r6-windows\android-ndk-r6\toolchains\arm-linux-androideabi-4.4.3\prebuilt\windows\bin directory.

但是，当我想读是gmon.out使用下面的命令......

But when I am trying to read gmon.out using the following command...

D:\android\android-ndk-r6-windows\android-ndk-r6\toolchains\arm-linux-androideab
i-4.4.3\prebuilt\windows\bin>arm-linux-androideabi-gprof D:\InternetTV_FD_Canvas
\libs\armeabi\libitv.so > out.txt

这是错误...显示

arm-linux-androideabi-gprof: file `D:\InternetTV_FD_Canvas\libs\armeabi\libitv.so'
 has no symbols

我不能够做出来的，为什么这个错误来了连我都做了一切正常。

任何人都可以请帮助我。

Can anybody please help me.

任何帮助将AP preciated。

Any help will be appreciated.

先谢谢了。

推荐答案

NDK的构建过程将创建2库，其中一个符号，一个没有剥离。您安装的剥离，符号库少你的APK，但你需要使用剥开版本使用gprof。如果你运行：

The NDK build process creates 2 libraries, one with symbols and one stripped without. You install the stripped, symbol-less library in your APK, but you need to use the unstripped version with gprof. If you run:

arm-linux-androideabi-gprof D:\InternetTV_FD_Canvas\obj\local\armeabi\libitv.so

...那么，应该是正确的库。

... then that should be the correct library.
