我有这个奇怪的问题,每当我#include "SDL/SDL.h"
,我的Windows套接字程序都不会执行。它可以编译但运行时不会执行任何操作。当我删除#include "SDL/SDL.h"
标题,编译并运行时,它会再次开始工作??。
我正在尝试使SDL和我的原始套接字程序都能正常工作,但我不明白这是错误的。
//#include "SDL/SDL.h"
#define _WIN32_WINNT 0x501
#include <iostream>
#include <windows.h>
#include <winsock2.h>
#include <ws2tcpip.h>
#include <string.h>
#include <ws2tcpip.h>
#define MAXLEN 80
using namespace std;
const int winsockVersion = 2;
int main( int argc, char* args[] ) {
WSADATA wsadata;
if ( (WSAStartup(MAKEWORD(2,0),&wsadata)) == 0){
cout<<"-[ WSAStartup Initialized. ]" << endl;
char PORT[MAXLEN];
char SERVER[MAXLEN];
cout <<"Server: ";
cin>>SERVER;
cout <<"Port: ";
cin>>PORT;
struct addrinfo hints, *res;
int sockfd;
memset(&hints,0,sizeof hints);
hints.ai_family = AF_UNSPEC;
hints.ai_socktype = SOCK_STREAM;
if (getaddrinfo(SERVER,PORT,&hints,&res) != 0){
cout<<"-Getaddrinfo unsuccessful." << endl;
}
if ( (sockfd = socket(res->ai_family,res->ai_socktype,res->ai_protocol)) == -1 ){
cout<<"-Unable to create socket." << endl;
}
if ( (connect(sockfd,res->ai_addr,res->ai_addrlen)) != -1 ){
cout<<"-[ Connection Established. ]" << endl;
}
cout<<"-[ Client connecting to: ]" << res->ai_addr << endl;
while(true){
string text_buff;
cout<<"Send: ";
getline(cin,text_buff);
if( (send(sockfd,text_buff.c_str(),text_buff.length()+1,0)) != -1 ){
cout<<"-----------------------------------> Data sent!." << endl;
}
if ( text_buff == "quit" ){
break;
}
}
}else{
cout<<"-WSAStartup Initialization failed." << endl;
if(WSACleanup()!=0){
cout<<"-WSACleanup Successful." << endl;
}else{
cout<<"-WSACleanup Failed." << endl;
}
}
return 0;
}
使用
进行编译g++ -o draft.exe draft.cpp -I"C:\compilers and libs\Libs\SDL\SDL devep\SDL-1.2.15\include" -L"C:\compilers and libs\Libs\SDL\SDL devep\SDL-1.2.15\lib" -lmingw32 -lSDLmain -lSDL -lws2_32
答案 0 :(得分:1)
据我所知,SDL用一些愚蠢的#define main
技巧重写了主要功能,它就像那样拦截程序主。
因此,可能根本没有调用main。
如果我没记错,你的主要功能(参数)应该完全 int main(int argc, char *argv[])
。
