使用B. Stroustrup的编程文本和关于pg 50的'hello world'程序会产生错误.我有"std_lib_facilities.h"包含文件的问题.
运行后(以root身份)'gcc hworld1.cpp'输出为 -
In file included from /usr/include/c++/4.4/ext/hash_map:60,
from std_lib_facilities.h:34,
from hworld1.cpp:1:

任何建议如何修复文件,也许注释掉哈希部分？
兴奋到最后有时间开始,但这似乎比第一个故障排除任务大一点.我试过使用iostream作为包含.我在Ubuntu 11.04上运行它.也许我需要更新gcc或使用g ++.不知道是什么可以让我轻松过去.我用'使用... std'和...做了一些事情,作为我不记得的合适的名字(哎呀).任何人都知道权利包括.
这是代码 -
#include "std_lib_facilities.h"
int main()
{
cout<<"hiya people\n";
return 0;
}
