    <p>I am trying to experiment the C++11 threads in a way that it accepts a member function of a class as a parameter into the thread constructor as shown in the first code snippet below on line 20 that is marked . The class definition is given in the 2nd code snippet. When this code is compiled, I am getting a bunch of errors shown in the 3rd snippet. Can anyone tell me what I am doing wrong? Thanks.</p> <p><strong>SNIPPET 1: Thread initialization (main_app.cpp)</strong></p> <pre><code>#include &lt;thread&gt; #include "ServiceRegistrar.hpp" #define SERVER_TYPE 100065 #define SERVER_INST_LOWER 1 #define SERVER_INST_UPPER 2 #define TIMEOUT 500000 int main() { ServiceRegistrar sr1(SERVER_TYPE, TIMEOUT, SERVER_INST_LOWER, SERVER_INST_LOWER); /*LINE 20 is the following*/ std::thread t(&amp;ServiceRegistrar::subscribe2TopologyServer, sr1); t.join(); sr1.publishForSRs(); } </code></pre> <p><strong>SNIPPET 2: Class definition</strong></p> <pre><code>class ServiceRegistrar { public: ServiceRegistrar(int serverType, int serverTimeOut, int serverInstanceLower, int serverInstanceUpper) : mServerType(serverType), mServerTimeOut(serverTimeOut), mServerInstanceLower(serverInstanceLower), mServerInstanceUpper(serverInstanceUpper) { } void subscribe2TopologyServer(); void publishForSRs(); void publishForServices(); private: int mServerType; int mServerTimeOut; int mServerInstanceLower; int mServerInstanceUpper; }; </code></pre> <p><strong>SNIPPET 3: Compilation output</strong></p> <pre><code> $ g++ -g -c -Wall -std=c++11 main_app.cpp -pthread In file included from /usr/include/c++/4.7/ratio:38:0, from /usr/include/c++/4.7/chrono:38, from /usr/include/c++/4.7/thread:38, from main_app.cpp:8: /usr/include/c++/4.7/type_traits: In instantiation of ‘struct std::_Result_of_impl&lt;false, false, std::_Mem_fn&lt;void (ServiceRegistrar::*)()&gt;, ServiceRegistrar&gt;’: /usr/include/c++/4.7/type_traits:1857:12: required from ‘class std::result_of&lt;std::_Mem_fn&lt;void (ServiceRegistrar::*)()&gt;(ServiceRegistrar)&gt;’ /usr/include/c++/4.7/functional:1563:61: required from ‘struct std::_Bind_simple&lt;std::_Mem_fn&lt;void (ServiceRegistrar::*)()&gt;(ServiceRegistrar)&gt;’ /usr/include/c++/4.7/thread:133:9: required from ‘std::thread::thread(_Callable&amp;&amp;, _Args&amp;&amp; ...)

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.
