solaris菜鸟求教boost thread问题~~
尝试用boost::thread写了一个多线程的测试，大概内容如下：

C/C++ code

#include <boost/thread/thread.hpp>#include <boost/bind.hpp>#include <iostream>using namespace std;void wait(int seconds)   {       boost::this_thread::sleep(boost::posix_time::seconds(seconds));   } class A2{    DEFINE_SINGLETON(A2)     //定义为单件模式；public:    A2()    {        t = 0;        bStop = false;    }public:    void dis()    {        bStop = false;        while(t < 5)        {            cout<<"A2 display running..."<<endl;            wait(1);            ++t;        }        cout<<"A2 displaying is stopped"<<endl;        bStop = true;    }    bool stop()    {        return bStop;    }private:    bool bStop;    int t;};class A1{    DEFINE_SINGLETON(A1)public:    A1()    {        i = 0;        j = 0;        a = 'a';        bEnd = false;    }    void disp()    {        cout<<"i = "<<i<<endl;        i++;        cout<<"After, i = "<<i<<endl;        cout<<endl;        cout<<endl;        cout<<"a is "<<a<<endl;        a = a+1;        cout<<"After, a is "<<a<<endl;    }    void stay()    {        bEnd = false;        while(false == A2::getInstRef().stop())        {            cout<<"***"<<endl;            wait(1);        }        cout<<"thread B stopped by A2 display"<<endl;        cout<<endl;        bEnd = true;    }    bool stay_end()    {        return bEnd;    }private:    int i;    int j;    bool bEnd;    char a;};

main函数那边是这样写的：

C/C++ code

#include <boost/shared_ptr.hpp>int main(int argc, char* argv[]){    int iEnd;    boost::shared_ptr<boost::thread> testA(new boost::thread(boost::bind(&A2::dis, A2::getInstPtr())));    boost::shared_ptr<boost::thread> testB(new boost::thread(boost::bind(&A1::stay, A1::getInstPtr())));    cout<<endl;    //    boost::shared_ptr<boost::thread> testB(boost::bind(&A2::dis, A2::getInstPtr()));    cin>>iEnd;      return 0;}

这个测试大概就是A1中的函数一直运行，希望通过A2中的函数的变化去控制A1中的函数的执行。我想尝试的东西是在单件模式下线程之间的控制。



这样写好后在windows下编译可以通过没有问题。

可是拿到solaris下用sunstudio编译则无法通过，显示的错误如下：
"boost/exception_ptr.hpp", line 111: Warning: Function boost::exception_ptr::~exception_ptr() can throw only the exceptions thrown by the function boost::exception_detail::exception_ptr_base::~exception_ptr_base() it overrides.

这个错误是什么意思呢？是thread里面的析构函数出问题了吗？第一次编译的时候说不支持多线程，让我在工程属性里加上 -mt，我加上以后就报这个错误了，研究了老半天还是云里雾里的，网上也没找到关于这个问题的介绍。有没有哪些高人给小弟指点一二？

非常感谢~~！

不懂，但是帮你顶一下！
