我认为想解决问题可以通过 重新将linux下的string的调用,包括成员函数等重新替换成window下的,如果window中的string类没有的话就要自己实现或者改代码。
不知道能不能通过typedef或者预编译方式来移植,或者对string进行重载,使其成员和linux下的保持一致,这样应该可以少做工作,不过可行度未知。

我的意思是如果你按照linux的方式重写string类的话,就不需要该里面的代码了,只需要在前面用typedef下就行了。不过感觉这个应该比较麻烦
|
只拷头文件当然没用了,还得有库啊,而且vc.net也有string的库啊,可以把相关的string处理修改下就行了
|
这种头文件怎么能直接复制呢??这可是两个不同的平台啊
移植程序决不能这样做的。
