急问，powerpc-.....-g++交叉编译的时候不支持c++标准库，该怎么办？？

oubu2000

如题，谢谢！！！！

T-bagwell

你指的C++标准库是什么意思？

oubu2000

比如说cout函数，vector库函数什么的，谢谢，是不是g＋＋版本太低的原因啊

T-bagwell

能说说你怎么编译的c++的库的吗？
板子上有c++的库没？

提示的错误是什么样的呢？

oubu2000

我写了一个c++的函数，其中包含cout和vector，编译通不过，说是找不到这两个函数，所以我觉得是不是因为板子上的g＋＋编译器版本太低，所以没有把c＋＋标准库包含进去，如果是这样的话，请问你知不知道在那里下载高版本的g++编译器啊，非常感谢！！！


另外，我的power pc还不支持浮点运算，在编译内核时加入什么才能叫它支持呢？？？？

T-bagwell

跟编译器没关系吧？
你这样吧

uname -a
arm-linux-gcc -v
arm-linux-g++ -v
编译你的程序的例子，包括参数
cat /etc/ld.so.conf

都贴出来

oubu2000

非常感谢！！！

程序cc.cpp：
#include <iostream>
using namespace std;
int main()
{
  cout<<"hello world\n"<<endl;
return 0;
}

# uname -a

很着急，但是不知道该怎么办，谢谢帮忙。

字面上看是lib的问题
实际上就不知道了
我用的都是好好的，呵呵
