Valgrind 如何在arm上使用

zjf30366

程序在arm上跑，但有内存泄漏，由于工程有些大，单纯查代码很难找到，于是想用Valgrind 来查找内存在哪里泄漏的。
但问题是在Linux上编译Valgrind 的时候提示 no arm。
Valgrind 使用的是3.6.1，虚拟机安装的Linux系统的是2.6.23
在Valgrind 目录执行./configure --host=arm-linux ，提示以下错误

是否有哪位大牛用过valgrind在arm上检测内存泄漏，改如何生成这个程序呢，求解。

who can help me？

交叉编译总会遇到这样那样的问题是需要手动去调整和修改的
像楼主这个问题只需要调整configure脚本就可以了
具体应该在检查host_os变量里加入匹配arm条件就行了，如原有的armv7*)改成armv7*|arm)

valgrind移植是怎么弄的 方便透漏吗？我查了很多资料都没看到，请问你们是从哪里查到的资料 能告诉我吗

这样搞还是不行

按上面的修改configure文件。肯定可以匹配arm目标平台的armv7*|arm)
