不用搞4.7.1了. 已经出4.7.2了....
现在编译gcc请准备gmp/mpc/mpfr/cloog/ppl这几个库.另外,还请注意版本,太新或太旧也不行.

libmpc.so就是mpc这库.你看下版本,配置之类的吧.
现在的gcc已经很好编译了.不像以前.经常出问题...

我知道是什么问题了，给LD_LIBRARY_PATH赋值时少了/lib段

我刚编译了4.7.2了，只是运行还不太正常，不太清楚是哪儿的问题，还需要再深入一下

运行不正常?是什么状况?
我分别编译了x86-linux/win32下针对4个不同target的版本,没见有什么问题啊

比如一面这段程序：

#include <iostream>

#include<thread>

using namespace std;

void thread_fun()

{

	for (int i = 0 ; i < 100 ; ++i)

	{

		cout<<i<<endl;

	}

}

int main()

{

	thread t(thread_fun);

	t.join();

	return 0;

}

应该是没什么问题的吧？

在gcc-4.7.2下编译也没问题，在运行时出错：
terminate called after throwing an instance of 'std::system_error'
  what():  Operation not permitted
我以前没怎么在LINUX下写过程序，不太清楚这是为什么，还请各位指教

顺便说一下，我是照着
http://www.oschina.net/question/12_49423
做的，只是红薯没说要export LD_LIBRARY_PATH

在使用g++里还需要LD_LIBRARY_PATH指明mpc库的位置？

引用 7 楼  的回复:

比如一面这段程序：
C/C++ code

#include <iostream>
#include<thread>
using namespace std;
void thread_fun()
{
    for (int i = 0 ; i < 100 ; ++i)
    {
        cout<<i<<endl;
    }
}
int main()
{
    thread ……

google了下，发现：What is wrong with this use of std::thread?
