MFC 静态链接未解析的外部符号

Question

我正在尝试使用 Use of MFC:Use MFC in a Static Library 构建自定义版本的 GyazoWin，这会导致大量参考错误。

如何安抚 Visual Studio，以便我可以使用静态链接库进行构建？

更新

我设法将 user32 添加到链接库中（我认为），现在我的错误数量只有 1/3。谁能告诉我现在缺少什么库？

Answer 1

对于来自平台库的功能：

1. 使用您喜欢的搜索引擎搜索函数的名称（例如“GetStockObject”）。

2. 在 MSDN 上查找该函数的文档（例如 GetStockObject）。它通常是最好的结果之一。

3. 在文档中的“要求”下，找到“库”条目。那是您必须链接到的库才能使用该函数（对于GetStockObject，它是 gdi32.lib）。

4. 重复直到解决所有错误。
