舉報(bào) 分類：
c/c++（11）
1、從http://sourceware.org/pthreads-win32/下載pthread 的windows安裝包，我下的是pthread-w32-2-9-1-release.zip，其他版本也可以。解壓到pthread-w32-2-9-1-release。
2、打開vs2010，項(xiàng)目->屬性->配置屬性->VC++目錄，包含目錄里添加inlude路徑，如下圖所示，如果剛下載的壓縮包放在D盤，則在包含目錄那一欄添加：D:\pthread-w32-2-9-1-release\Pre-built.2\include;在庫目錄那一欄添加：D:\pthrea-w32-2-9-1-release\Pre-built2\lib
3、在鏈接器—>輸入，附加依賴項(xiàng)一欄添加
pthreadVC2.lib;pthreadVCE2.lib;pthreadVSE2.lib;如下圖所示。所有設(shè)置完成后點(diǎn)確定。
4、打開pthread-w32-2-9-1-release\Pre-built.2\lib\X86，將里面三個(gè)*.lib文件復(fù)制到你所建立的工程目錄中去，這樣就設(shè)置好了，大功告成。
如下一個(gè)簡(jiǎn)單的程序?qū)嵗?div style="height:15px;">
[cpp]
view plain copy#include<stdio.h>
#include<stdlib.h>
#include<pthread.h>
#define NUM_THREADS 4
typedef struct{
int threadId;
}threadParm_t;
void *threadFunc(void *parm)
{
threadParm_t *p=(threadParm_t *)parm;
fprintf(stdout,"Hello world from thread%d\n",p->threadId);
pthread_exit((void *)&(p->threadId));
return 0;
}
int main(int argc,char *argv[])
{
int i;
int *res;
res=(int *)malloc(sizeof(int));
pthread_t thread[NUM_THREADS];
threadParm_t threadParm[NUM_THREADS];
for(i=0;i<NUM_THREADS;i++)
{
threadParm[i].threadId=i;
pthread_create(&thread[i],NULL,threadFunc,(void *)&threadParm[i]);
}
for(i=0;i<NUM_THREADS;i++)
{
pthread_join(thread[i],(void **)&res);
fprintf(stdout,"Thread %d has exited.\n",*res);
}
system("pause");
return 0;
}
運(yùn)行程序得到如下結(jié)果。
如果運(yùn)行時(shí)，提示缺少“pthreadVC2.dll”，將pthread目錄下的pthreadVC2.dll文件拷貝到C:\Windows\System32（32位系統(tǒng)）中即可
