所以我试图用Visual Studio Code中的c ++创建一个Windows桌面应用程序,并使用MinGW作为我的编译器。我在名为src的文件夹中有一个名为test.cpp的文件:
#ifndef UNICODE
#define UNICODE
#endif
#include <windows.h>
int wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PWSTR lpCmdLine,
int nCmdShow){
const wchar_t name[] = L"Test";
WNDCLASS wc = {};
//wc.lpfnWndProc = WindowProc;
wc.hInstance = hInstance;
wc.lpszClassName = name;
RegisterClass(&wc);
HWND hWnd = CreateWindowEx(
0,
name,
L"Window",
WS_BORDER,
CW_USEDEFAULT,
CW_USEDEFAULT,
1200,
720,
0,
0,
hInstance,
0);
if(hWnd == NULL){
return 0;
}
ShowWindow(hWnd, nCmdShow);
}
但是当我编译时,我得到了这个错误:
> Executing task: g++ -g test.cpp -o test.exe <
c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../libmingw32.a(main.o):(.text.startup+0xa0): undefined reference to `WinMain@16'
collect2.exe: error: ld returned 1 exit status
The terminal process terminated with exit code: 1
我还在.vscode文件夹中有tasks.json和launch.json:
tasks.json
"version": "2.0.0",
"tasks": [
{
"label": "test",
"type": "shell",
"command": "g++",
"options": {
"cwd": "${workspaceFolder}/src"
},
"args": [
"-g", "test.cpp", "-o", "test.exe"
],
"group": {
"kind": "build",
"isDefault": true
}
}
]
Launch.json
"version": "0.2.0",
"configurations": [
{
"name": "(Windows) Launch",
"type": "cppvsdbg",
"request": "launch",
"program": "${workspaceFolder}/src/test.exe",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}/src",
"environment": [],
"externalConsole": true,
"preLaunchTask": "test"
}
]
问题是,当我使用main函数构建一个文件时,它编译得很好,但是当wWinMain完成时发生错误并且我不知道如何修复它。如果有人可以帮助我,我真的很感激。
WinMain @ 16通常在您尝试编译某些文件时出现,这些文件不包含main()/WinMain()
函数(程序的起点)。在你的情况下,不包括带有main()/WinMain()
函数的源文件导致你的麻烦。
