android开发----6.valgrind在android下的使用

1. 编译方法 
参考valgrind-3.12.0下面的README.android
1.1 32位下的编译
cong@msi:/work/valgrind/valgrind-3.12.0$ cat build.sh

export NDKROOT=/work/bak/android/android-ndk-r10d/
export HWKIND=generic
export AR=$NDKROOT/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-ar
export LD=$NDKROOT/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-ld
export CC=$NDKROOT/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc
export RANLIB=$NDKROOT/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-ranlib
export STRIP=$NDKROOT/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-strip
export CPPFLAGS="--sysroot=$NDKROOT/platforms/android-21/arch-arm -DANDROID_HARDWARE_$HWKIND -DVGPV_arm64_linux_android=1"
export CFLAGS="--sysroot=$NDKROOT/platforms/android-21/arch-arm"
export LIBS="-L$NDKROOT/platforms/android-14/arch-arm/usr/lib"
./configure --host=armv7-unknown-linux --target=arm-linux-androideabi --prefix=/data/local/Inst --with-tmpdir=/sdcard

1.2 执行脚本build.sh
cong@msi:/work/valgrind/valgrind-3.12.0$ ./build.sh

Maximum build arch: arm
         Primary build arch: arm
       Secondary build arch:
                   Build OS: linux
       Primary build target: ARM_LINUX
     Secondary build target:
           Platform variant: android
      Primary -DVGPV string: -DVGPV_arm_linux_android=1
         Default supp files: exp-sgcheck.supp xfree-3.supp xfree-4.supp bionic.supp

1.3 64位下的编译

cong@msi:/work/valgrind/valgrind-3.12.0$ cat build.sh
export NDKROOT=/work/bak/android/android-ndk-r10d/
export HWKIND=generic
export AR=$NDKROOT/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64/bin/aarch64-linux-android-ar
export LD=$NDKROOT/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64/bin/aarch64-linux-android-ld
export CC=$NDKROOT/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64/bin/aarch64-linux-android-gcc
export RANLIB=$NDKROOT/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64/bin/aarch64-linux-android-ranlib
export STRIP=$NDKROOT/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64/bin/aarch64-linux-android-strip
export CPPFLAGS="--sysroot=$NDKROOT/platforms/android-21/arch-arm64 -DANDROID_HARDWARE_$HWKIND -DVGPV_arm64_linux_android=1"
export CFLAGS="--sysroot=$NDKROOT/platforms/android-21/arch-arm64"
export LIBS="-L$NDKROOT/platforms/android-14/arch-arm/usr/lib"
./configure --host=aarch64-unknown-linux --target=aarch64-linux-androideabi --prefix=/system/bin/Inst --with-tmpdir=/sdcard

1.4 执行脚本build.sh

Maximum build arch: arm64
         Primary build arch: arm64
       Secondary build arch:
                   Build OS: linux
       Primary build target: ARM64_LINUX
     Secondary build target:
           Platform variant: android
      Primary -DVGPV string: -DVGPV_arm64_linux_android=1
         Default supp files: exp-sgcheck.supp xfree-3.supp xfree-4.supp bionic.supp

2. 编译及安装
2.1 编译
cong@msi:/work/valgrind/valgrind-3.12.0$ make -j8  
cong@msi:/work/valgrind/valgrind-3.12.0$ make -j8 install DESTDIR=`pwd`/Inst 
2.2 将valgrind的可执行文件导入手机
cong@msi:/work/valgrind/valgrind-3.12.0$ adb push Inst / -->文件比较多,打包再导入会更好一点

3. valgrind执行脚本并导入手机
3.1 valgrind 的执行脚本

cong@msi:/work/valgrind/valgrind-3.12.0$ cat val.sh -->编辑执行脚本
#!/system/bin/sh
VGPARAMS='--error-limit=no --kernel-variant=android-gpu-adreno510'
export TMDIR=/data/data/com.qileyx.ddz.vivo/
export VALGRIND_LIB=/system/bin/Inst/lib/valgrind/      -->如果出现memcheck找不到的提示,需要加这个
exec /system/bin/Inst/bin/valgrind $VGPARAMS $*

3.2 脚本的导入
cong@msi:/work/valgrind/valgrind-3.12.0$ adb push ./val.sh  /system/bin/Inst/ -->push到/system/bin/Inst下


cong@msi:/work/valgrind/valgrind-3.12.0$ adb shell chmod 777 /system/bin/Inst/val.sh -->增加可执行权限
cong@msi:/work/valgrind/valgrind-3.12.0$ adb shell ls -l /system/bin/Inst/val.sh     -->查看可执行权限
-rwxrwxrwx root     root          138 2017-03-18 10:38 val.sh


4. 在手机上运行apk
export VALGRIND_LIB=/system/bin/Inst/lib/valgrind/


adb shell am force-stop com.example.hellojni    -->关闭进程
adb shell setprop wrap.com.example.hellojni "logwrapper /system/bin/Inst/val.sh"   -->加入wrapper
adb shell am start -a android.intent.action.MAIN -n com.example.hellojni/.HelloJni  -->启动进程


adb shell am force-stop com.example.hellojava 
adb shell setprop wrap.com.example.hellojava "logwrapper /system/bin/Inst/val.sh"
adb shell am start -a android.intent.action.MAIN -n com.example.hellojava/.HelloJava

5. 问题 
先在/system/bin/Inst/bin/valgrind 运行没有问题后再写脚本

5.1 运行时报错
I/val.sh  (11189): valgrind: failed to start tool 'memcheck' for platform 'arm64-linux': No such file or directory
这需要export VALGRIND_LIB=/system/bin/Inst/lib/valgrind/


5.2 关于版本
cong@msi:/work/valgrind/valgrind-3.12.0$ file top   -->这个top文件是从手机里面导出来的
top: ELF 64-bit LSB  shared object, ARM aarch64, version 1 (SYSV), dynamically linked (uses shared libs), stripped
cong@msi:/work/valgrind/valgrind-3.12.0$ file Inst/data/local/Inst/bin//valgrind
Inst/data/local/Inst/bin//valgrind: ELF 32-bit LSB  executable, ARM, EABI5 version 1 (SYSV), statically linked, not stripped


重新用64位的ndk编译之后的file结果:
cong@msi:/work/valgrind/valgrind-3.12.0$ file Inst/data/local/Inst/bin//valgrind
Inst/data/local/Inst/bin//valgrind: ELF 64-bit LSB  executable, ARM aarch64, version 1 (SYSV), statically linked, not stripped

6. 最后有一个问题 valgrind 检查native的程序时正常,但是检查apk的程序时失败
Error reading pid form wrapped process, child may have died. --->没有解决这个问题, 如果有大牛知道了,麻烦告诉我一下,谢谢.
