再次感谢诺基亚论坛的 beover1984 提供帮助�Q?br>
【参考文章】：http://www.symbian.net.cn/blog/post/5.html

声明�Q�虽然上面的【参考文章】标题是 Use HookLogger to trace memroy leak in S60 3rd SDK �Q�但 S60 �W�二版也适用�Q?br>
需要说明的�?EPOCROOT 是在 Windows �pȝ��变量中改的且前后都要�?#8220;/”(不是 Windows 下用�?#8220;\”)

也可以不用系�l�变量而直接��用下面的 perl 代码替换 HookEUSER.pl 的内�?nbsp;, �q�把�W?3行改��Z��?SDK 路径�Q�注意无盘符�Q�：

�q�样你只要安装完 HookLogger �q�按照上面的�Ҏ��更新 HookEUSER.pl�Q�再按照【参考文章】运行程序就行了�?br>�E�序的��用很��单，�q�里不再赘述�?br>定位到内存泄露的地方后剩下的事就交给你了~~
