GCCe（release） 编译的时候出现的问题
发布: 2010-4-15 17:47 | 作者: fys85 | 来源: DevDiv 移动开发社区
在模拟器环境先编译的时候没有错误，换到GCCE (release )的时候出现了
note: neither the destructor nor the class-specific operator delete will be called, even if they are declared when the class is defined.[..//..//..//Symbian//9.1//S60_3rd_MR//EPOC32//include/e32base.inl]
不知道这样的错误是怎么回事？怎么解决？请高手帮忙！

上面是写好的一个TAB控件，在一个VIEW里面NEW 一个控件的对象，在GCCE（release）环境下编译就可以看到编译的错误了，很是不解...

void SetIconArray(CArrayPtr<CGulIcon>* aIconArray) // takes the ownership
{
if(iIconArray != NULL)
{
iIconArray->ResetAndDestroy();
}
iIconArray=aIconArray;
}这个函数的IconArray->ResetAndDestroy();这一句

Symbian 编译的诡异问题出得多了之后，我找到一个成功概率极其高的解决办法：把 SDK 的 epoc32 目录下的 BUILD 目录整个删除，然后再编译，十有八九可以搞定。
