emerge python * configure has detected that the sem_open function is broken.

* ERROR: dev-lang/python-2.7.5-r3::gentoo failed (configure phase):

* Broken sem_open function (bug 496328)

* die "Broken sem_open function (bug 496328)"

以上3条提示错误，你这个应该是应用程序的编程阶段或者测试。错误处修改，或者上下路逻辑检查

简单一点的,r,t分别产生两组随机数，你往后加参数即可：

#include<stdlib.h>

#include<stdio.h>

int main(void){

int r=srandom((int)time(0))

int t=srandom((int)time(0))

printf("%d %d\n",r,t)

return 0

}
