Question

我一直试图在过去几个小时内调试此错误，但无济于事使用以下批处理文件构建程序时，

    REM Build process for text editor
@echo off
pushd build
cl /Zi /MDd /IC:\Users\Giovanni\dev_lib\SDL2-2.0.4\include /I"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include" /I"C:\Program Files (x86)\Windows Kits\8.1\Include\shared" ..\*.c /link /NODEFAULTLIB:msvcrt.lib /ENTRY:mainCRTStartup /SUBSYSTEM:console /LIBPATH:C:\Users\Giovanni\dev_lib\SDL2-2.0.4\lib\x64 /LIBPATH:C:\Users\Giovanni\dev_lib\SDL2_image-2.0.1\lib\x64 SDL2.lib SDL2main.lib SDL2_image.lib /out:text_editor.exe
popd

我在CMD中收到以下错误消息：

Microsoft (R) C/C++ Optimizing Compiler Version 18.00.31101 for x86

main.c
..\main.c(36) : error C2143: syntax error : missing ')' before 'type'

我的全班都在这里：

#include <assert.h>
#include <stdio.h>
#include <SDL.h>

#define BOOL u32
#define TRUE 1
#define FALSE 0

#define SCREEN_WIDTH 1024
#define SCREEN_HEIGHT 576

typedef Uint32 u32;
typedef Uint64 u64;
typedef Sint32 i32;
typedef Sint64 i64;

int main (int argc, char *argv[]) {

    SDL_Init(SDL_INIT_VIDEO);

    SDL_Window *win = SDL_CreateWindow("Text Editor",
                                        SDL_WINDOWPOS_UNDEFINED, 
                                        SDL_WINDOWPOS_UNDEFINED, 
                                        SCREEN_WIDTH, SCREEN_HEIGHT, 0);
    assert(win);

    SDL_Renderer *renderer = SDL_CreateRenderer(win, 0, SDL_RENDERER_SOFTWARE);
    assert(renderer);

    SDL_Texture *screen = SDL_CreateTexture(renderer, 
                                            SDL_PIXELFORMAT_RGB888, 
                                            SDL_TEXTUREACCESS_STREAMING, 
                                            SCREEN_WIDTH, SCREEN_HEIGHT);
    assert(screen);

    u32 *screen_pixels = (u32*) calloc(SCREEN_WIDTH * SCREEN_HEIGHT, sizeOf(u32));
    assert(screen_pixels);

    SDL_Delay(3000);

}

（它只有40行）

如果你能解释我做错了什么（我是C的新手），那将非常有帮助！谢谢！

Answer 1

该消息表明错误在第36行。

..\main.c(36) : error C2143:

我相信这是第36行：

 u32 *screen_pixels = (u32*) calloc(SCREEN_WIDTH * SCREEN_HEIGHT,sizeOf(u32));

你看到有任何错别字吗？你能识别每一个变量并在该行上进行调用吗？

sizeof与sizeOf
不同

Answer 2

我没有运行Windows，但这看起来很奇怪：

u32 *screen_pixels = (u32*) calloc(SCREEN_WIDTH * SCREEN_HEIGHT, sizeOf(u32));

您是否尝试过sizeof没有资金O？

错误c2143：语法错误：'type'之前缺少'）'
