提升1.48 海湾合作委员会 4.2.4 AIX 5.3 PowerPC

我有一个 C 应用程序，被告知要移植到 C++，现在我需要使用正则表达式。因此，自从圣诞节以来，我一直在学习 C++（实际上我真的很喜欢它，已经好几周没见到妻子了）。因此，我必须使用 GCC 将应用程序移植到 AIX 5.3。我只对正则表达式使用 boost。我有一个简单的测试示例，可以编译并运行良好，但是在编译时我收到这些警告。任何人都可以建议a）忽略它们是否安全b）如果不是那么我做错了什么c）有人认为浓咖啡和深夜是学习C ++的好计划吗？

这是示例：＃包括 #include

bool isPluginPresent(const std::string& s)
{
    static const boost::regex e("^(Plugin|area-Hub-Plugin):\s*(.*arealdap.+)$", boost::regex::perl|boost::regex::icase);
  return boost::regex_match(s, e);
}

#include <iostream>
using namespace std;

int main()
{
    string s[6] = { "Pluuuugin: c:\\program files\\nextid.dll", 
                    "Plugin: c:\\program files\\areahub.dll",
                "AREA-Hub-Plugin: c:\\program files\\arealdap.so",
                          "AREA-Hub-Plugin: c:\\program files\\someother.so", 
                  "Hello World: I really should go to bed",
                "Plugin:            c:\\program files\\arealdap.so",};
   int i;
   for(i = 0; i < 6; ++i)
   {
       cout << "isPluginPresent " << s[i] << " returned " << isPluginPresent(s[i]) << endl;
   }

   return 0;
}

编译时使用 g++ -I /home/smurff/boost_1_48_0 -lpthreads example.cpp -o example /usr/local/lib/libboost_regex.a

警告是一大堆这样的：

ld: 0711-224 警告: 重复的符号: .non-虚拟重击boost::exception_detail::error_info_injector::~error_info_injector()

感谢您的宝贵时间丹尼

Boost 1.48
GCC 4.2.4
AIX 5.3 PowerPC

I have a C app that I have been told to port to C++ and I now have a need to use regex. So since XMAS I have been learning C++ (And actually really loving it, not seen the wife in weeks tbh). So, I have to port an app over to AIX 5.3 using GCC. I am only using boost for the regex. I have a simple test example that compiles and runs fine, but when compiling I get these warnings. Can anyone advise on a) are they safe to ignore b)If not then what am I doing wrong c) Does anyone thing that strong coffee and late nights is a good plan for learning C++?

Here is the example:
#include
#include

bool isPluginPresent(const std::string& s)
{
    static const boost::regex e("^(Plugin|area-Hub-Plugin):\s*(.*arealdap.+)$", boost::regex::perl|boost::regex::icase);
  return boost::regex_match(s, e);
}

#include <iostream>
using namespace std;

int main()
{
    string s[6] = { "Pluuuugin: c:\\program files\\nextid.dll", 
                    "Plugin: c:\\program files\\areahub.dll",
                "AREA-Hub-Plugin: c:\\program files\\arealdap.so",
                          "AREA-Hub-Plugin: c:\\program files\\someother.so", 
                  "Hello World: I really should go to bed",
                "Plugin:            c:\\program files\\arealdap.so",};
   int i;
   for(i = 0; i < 6; ++i)
   {
       cout << "isPluginPresent " << s[i] << " returned " << isPluginPresent(s[i]) << endl;
   }

   return 0;
}

Compiled with
g++ -I /home/smurff/boost_1_48_0 -lpthreads example.cpp -o example /usr/local/lib/libboost_regex.a

And the warnings are a whole bunch like this:

ld: 0711-224 WARNING: Duplicate symbol: .non-virtual thunk to boost::exception_detail::error_info_injector::~error_info_injector()

Thanks for your time
Danny
