valgrind for android 编译安装

下载最新源码

1、配置configure脚本，由于是在linux服务器上编译的，/目录下没有权限，因此将prefix指定为自己目录下安装，

这样的话，一定要记得valgrind在手机放置的目录，必须和prefix指定的目录一致。

配置脚本build.sh见下，路径记得要改成自己的。

export NDKROOT=~/android-ndk-r8bexport HWKIND=generic#export VALGRIND_LIB=/data/local/valgrind/lib/valgrind/# Set up toolchain paths.## For ARMexport AR=$NDKROOT/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-arexport LD=$NDKROOT/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-ldexport CC=$NDKROOT/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc# for ARMCPPFLAGS="--sysroot=$NDKROOT/platforms/android-14/arch-arm -DANDROID_HARDWARE_$HWKIND" \   CFLAGS="--sysroot=$NDKROOT/platforms/android-14/arch-arm" \   ./configure --prefix=/home/myname/valgrind-3.9.0/valgrind-3.9.0/Inst \   --host=armv7-unknown-linux --target=armv7-linux-androideabi \   --with-tmpdir=/sdcard# note: on android emulator, android-14 platform was also tested and works.# It is not clear what this platform nr really is.

2、配置、编译、安装

./build.sh

make

make install

3、在prefix指定的目录下可以看到安装好的Inst，将其拷贝到手机侧，切记：一定要和prefix定义的路径一致，对应我现在定义的prefix，需要将Inst拷贝到

/home/myname/valgrind-3.9.0/valgrind-3.9.0/。

4、测试valgrind。进入手机侧/home/myname/valgrind-3.9.0/valgrind-3.9.0/Inst/bin，执行./valgrind ls，提示没有权限，ls -l可以看出根组其他用户都没有执行权限，chmod 777 valgrind；进入/home/myname/valgrind-3.9.0/valgrind-3.9.0/Inst/lib/valgrind，chmod 777 *，将所有文件权限修改。再执行./valgrind ls，出现如下画面。一切OK，开始使用valgrind吧。

注意事项：

1、手机侧放置valgrind的路径一定要和prefix定义一致，否则会出现如下错误

failed to start tool 'memcheck' for platform 'arm-linux': No such file or directory"。参见参考1。

2、如果使用cygwin模拟linux环境编译，configure中的kernel=`uname -r`检测内核时返回的是cgywin的版本号，

需要参考2进行修改。
