c++ - VC++，与 wxWidgets 链接错误，x64

Question

我正在使用 wxWidgets 2.8 在 Windows 7 x64 上编译一个 VC++ 10 应用程序。这就是我的错误。代码是使用 wxFormBuilder 生成的。

更新:我也尝试在 32 位机器上运行它，仍然有同样的问题。

我不知道我错过了哪些 wxwidgets 库，或者我做错了什么设置。在 Debug 和 Release 模式下都尝试过。

如果有人能指出一些提示，我将不胜感激!关注这个问题有一段时间了。

我正在链接的库(64 位 wxwidgets 库)

wxbase28.lib
wxmsw28_core.lib
wxmsw28_richtext.lib
wxmsw28_html.lib
wxmsw28_gl.lib
wxmsw28_adv.lib
comctl32.lib
Rpcrt4.lib

我的编译设置:

• 将 Wchat_t 视为内置类型:是
• 多线程调试 DLL

我找到了解决我自己问题的方法。只需张贴在这里以防有人遇到它。

这与 x64 或 x32 无关，也与 wxWidgets 无关。我只需要在标题中添加这两行(在 #include <wx/wx.h> 之前)

#define __WXMSW__
#define WXUSINGDLL
