    text
    copied!<p>I received this warning from <code>ld</code> whe I was buliding my program:</p> <blockquote> <p>ld: warning: direct access in global constructors keyed to <code>_ZN12_GLOBAL__N_143ensure_log_is_created_before_maing_l_filterEto</code> global weak symbol vtable for <code>cs::ObjectFactoryAliasInstantiation&lt;cs::DefaultCommandDispatcher&gt;</code> means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings.</p> </blockquote> <p>The code witch refer the error is this:</p> <pre><code>class ObjectFactory { public : ObjectFactory(const char *alias):sAlias(alias){}; std::string sAlias; virtual void* createInstance() = 0; }; template &lt;class T&gt; class ObjectFactoryAliasInstantiation : public ObjectFactory{ public: ObjectFactoryAliasInstantiation(const char *alias):ObjectFactory(alias){}; void* createInstance() { return (void*)new T(&amp;sAlias); }; };` </code></pre> <p>and this:</p> <pre><code> /* Class for register the dispatcher for the command */ class CommandDispatcherRegister { public: CommandDispatcherRegister(ObjectFactory *commandFactory); }; /* Macro for help the Command Dispatcher classes registration */ #define REGISTER_AND_DEFINE_COMMAND_DISPATCHER_CLASS(CMD_CLASS_NAME) class CMD_CLASS_NAME;\ static const CommandDispatcherRegister CMD_CLASS_NAME ## CommandDispatcherRegister(new ObjectFactoryAliasInstantiation&lt;CMD_CLASS_NAME&gt;(#CMD_CLASS_NAME));\ class CMD_CLASS_NAME : public CommandDispatcher\ </code></pre> <p>end this:</p> <pre><code> REGISTER_AND_DEFINE_COMMAND_DISPATCHER_CLASS(DefaultCommandDispatcher) { bool deinitialized; </code></pre>
