如何在Windows Vista上编译为Linux / Unix编写的C源代码(给出代码)

我有一个c源代码,由其他作者在linux / unix环境中编写.
当我在windows vista环境中编译它时,它给了我错误.我正在使用Bloodshed Dev C v 4.9.请帮忙.

解决方法:

在这里,我们得到了很好的编译器. mingw32-gcc编译器(这是DevCpp内置编译器)只是给出了一些这样的错误

error: dependent-name ` T::int' is parsed as a non-type, but instantiation yields a type

它不会将map< T,int> :: iterator作为一个类型,因为那取决于模板,你需要使用typename关键字作为依赖名称

因此,使用typename map< T,int> :: iterator

我已经完成了测试编译here.有源main.cpp文件和编译的.exe文件和一个数据文件.

看起来你从这里得到了这些代码

http://www.chasen.org/~taku/software/prefixspan/

它的GPL v2,您可能还需要将这些许可证添加到您的代码中.

编辑：添加固定代码供以后参考
