【问题描述】:
我一直在编写一个模板结构,在让它工作后,我决定在其他项目中使用它。该模板包含两个文件。 ListOctree.cpp 和 ListOctree.h。 虽然它们自己编译和运行都很好(我可以运行结构自检)。
在另一个项目中使用它们时,ListOctree.cpp/.h 都在 ./Util 目录中,但 Visual Studio 似乎找到了 .h 文件(我可以在项目的任何地方使用 .h 声明),似乎找不到 .cpp 源文件,其中声明了 .h 上声明的所有代码。
这些文件是项目的一部分。 ists 树是这样的:
program.cpp <-- includes "Util/ListOctree.h"
/Util
ListOctree.cpp
ListOctree.h
ListOctree 中的所有类和函数都属于 Util 命名空间。
Visual C++ 抛出的错误是: 错误 LNK2019: símbolo externo "public: __thiscall Util::ListOctree::ListOctree(int)" (...) sin resolver ...
大约。用英语: 错误 LNK2019:外部符号“public:__thiscall Util::ListOctree::ListOctree(int)”(...) 未解析 ...
重建解决方案时,Util/ListOctree.cpp 被编译为 .obj 文件,但似乎无法将其链接在一起
我也可以发布 .h 文件,但我觉得现在发布太长了。
附件:我在哪里以及如何使用 .h 文件
#include "Util/ListOctree.h"
//...
void main (){
//...
ListOctree<int>* a = new ListOctree<int>(8);
//...
}
