C:B wxwidgets 项目的编译器问题

Question

这是新手的问题：当我创建一个 wxWidgets 框架项目时，在我需要在函数中添加#include 时，我有这样的编译错误：

C:\wxWidgets-2.9.4\include\wx\msw\winundef.h||In function 'HWND__* CreateDialog(HINSTANCE, LPCTSTR, HWND, DLGPROC)':|
C:\wxWidgets-2.9.4\include\wx\msw\winundef.h|39|error: cannot convert 'LPCTSTR {aka const char*}' to 'LPCWSTR {aka const wchar_t*}' for argument '2' to 'HWND__* CreateDialogParamW(HINSTANCE, LPCWSTR, HWND, DLGPROC, LPARAM)'|

P:\c++\codeblocks\UDP SOCKET COM\Communication.cpp||In function 'void ConnectUDP()':|
P:\c++\codeblocks\UDP SOCKET COM\Communication.cpp|7|warning: unused variable 's' [-Wunused-variable]|
||=== Build finished: 7 errors, 1 warnings (0 minutes, 1 seconds) ===|

代码如下：

#include <winsock2.h>
#include <wx/msgdlg.h> 
#include <wx/string.h>

void ConnectUDP(){

SOCKET s;
int result;

WSADATA wsaData;
//initialize winsock
result = WSAStartup(MAKEWORD(2,2), &wsaData);
if(result != NO_ERROR){
    wxMessageBox("WSAStartup failed with error: " + wxString::Format(wxT("%i"),result));
}
}

这只发生在 c:b，我对 wxdev 或 vs2015 没有问题

您似乎在 wxWidgets 的 UNICODE 设置与您自己的代码之间存在不匹配，即您只需要在项目选项中定义 UNICODE。

也帮自己一个忙，停止使用 4 年前的开发版本，转而使用 3.1.0 或至少 3.0（目前最新的是 3.0.2）。
