    <p>Boost 1.48 GCC 4.2.4 AIX 5.3 PowerPC</p> <p>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++?</p> <p>Here is the example: #include #include </p> <pre><code>bool isPluginPresent(const std::string&amp; 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 &lt;iostream&gt; 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 &lt; 6; ++i) { cout &lt;&lt; "isPluginPresent " &lt;&lt; s[i] &lt;&lt; " returned " &lt;&lt; isPluginPresent(s[i]) &lt;&lt; endl; } return 0; } </code></pre> <p>Compiled with g++ -I /home/smurff/boost_1_48_0 -lpthreads example.cpp -o example /usr/local/lib/libboost_regex.a</p> <p>And the warnings are a whole bunch like this:</p> <p>ld: 0711-224 WARNING: Duplicate symbol: .non-virtual thunk to boost::exception_detail::error_info_injector::~error_info_injector()</p> <p>Thanks for your time Danny</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
