VC++,与 wxWidgets 的链接错误,x64
我正在使用 wxWidgets 2.8 在 Windows 7 x64 上编译 VC++ 10 应用程序。这就是我的错误。该代码是使用wxFormBuilder 生成的。
更新:我也尝试在32位机器上运行它,仍然遇到同样的问题。
我不知道我错过了哪些 wxwidgets 库,或者我做错了什么设置。在调试和发布模式下都尝试过。
如果有人能指出一些提示,我真的很感激!关注这个问题有一段时间了。

我的编译设置:
- 将 Wchat_t 视为内置类型:是
- 多线程调试 DLL
I'm compiling a VC++ 10 application on Windows 7 x64 with wxWidgets 2.8. And this is the errors I have. The code is generated using wxFormBuilder.
Update: I try to run it on 32-bit machine as well, still having the same problem.
I have no idea which wxwidgets libraries I'm missing out, or what settings did I do it wrong. Tried both in Debug and Release mode.
I'd really appreciate if someone could point to some hints! Been looking at this problem for a while.

你是如何构建 wxWidgets 的?我的理解是,您必须更改随 wxWidgets 分发的 Visual Studio 项目文件,以便它以 64 位模式构建。除非您的目标是 32 位模式。因此,请确保您的应用程序和 wxWidgets 的目标架构相同(即两者都应该是 32 位或 64 位)。
另外,最后我看到,wxWidgets 2.8不支持x64,如果你想针对x64,你需要升级到wxWidgets 2.9。
您还可以查看以下链接:http://wiki.wxwidgets.org/Supporting_x64_and_Win32_within_one_solution

我找到了解决我自己问题的方法。只要在这里发帖以防有人遇到它。
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
之前)I found the solution to my own problem. Just post here in case anyone faces it.
It's not about x64 or x32, neither about wxWidgets. I just need to add these 2 lines in header (before
#include <wx/wx.h>
)
