急：error LNK2001: unresolved external symbol _rindex

[daisy_cheung]

我将一些C程序从linux移植到windows，windows下缺少头文件strings.h，我就将Linux底下的该文件及相关文件拷贝过来，在使用visual studio 2005编译的时候出现类似这样的错误：

error LNK2001: unresolved external symbol _rindex

还有
Warning 12 warning C4996: 'sprintf' was declared deprecated e:\users\ddzhang\grapes\windows\tools\tools\src\gen_args.c 46
Warning 13 warning C4996: 'fopen' was declared deprecated e:\users\ddzhang\grapes\windows\tools\tools\src\gen_args.c 48
Warning 14 warning C4996: 'strcpy' was declared deprecated e:\users\ddzhang\grapes\windows\tools\tools\src\gen_args.c 51

会是什么原因呢？

strings.h的文件内容为：

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。

[daisy_cheung]

现在也是计划通过预编译方式来移植，先找出linux下strings.h所涉及函数的windows下的对应函数，然后再用预条件编译来做，有些晕。
你这里说的“对string进行重载，使其成员和linux下的保持一致”是什么意思？^_^

[lionc650]

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

[daisy_cheung]

明白了，谢谢。解决问题去了！

[lionc650]

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

[daisy_cheung]

在那个linux程序里面Include了string.h和strings.h两个，我对比了一下linux下的string.h和vc的string.h是不同的，那我得改写两个文件呀？另外strings.h还include了其他的一些linux下的.h文件，这写文件都得重写吗？

[悠悠长风]

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。

[daisy_cheung]

复制过来也是借着一种侥幸的心里。我第一次做移植，而且时间比较赶，能不能更详细些。

太复杂了，问题还是没能解决，能不能有更多的请教，加我的msn:[e-mail]
