valgrind

Google代码自带valgrind工具： xxx@u138-103:~/aosp/external/valgrind$ 

xxx@u138-103:~/aosp make -j64 valgrind           //即可生成valgrind

xxx@u138-103:~/aosp/external/valgrind$  mm     //生成相关的库文件   目录为： out/target/product/generic_arm64/system/lib64/valgrind/

adb push valgrind  /system/bin/

另外将out/target/product/generic_arm64/system/lib64/valgrind/中的库文件push到/system/lib64/valgrind （也可以是其它目录）中

并且export VALGRIND_LIB=/system/lib64/valgrind  

测试的程序：

// hello.c
#include <stdio.h>
#include <stdlib.h>
int main() {
  printf("aaaaaaaa\n");
  char *p = malloc(100);
  printf("bbbbbbb\n");
  return 0;
}        

 

#Android.mk
LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := hello
LOCAL_SRC_FILES := hello.c

include $(BUILD_EXECUTABLE)

 

kn:/system/lib64/valgrind # export VALGRIND_LIB=/system/lib64/valgrind
