hey all, I'm trying to build my own broker using C++ language ( g++-4.7.real (Debian 4.7.1-2) 4.7.1, nagios 3.4.1 ). Something goes wrong when g++ compiles the commandsmember structure in objects.h : /* COMMANDSMEMBER structure */ typedef struct commandsmember_struct { char *command; #ifdef NSCORE command *command_ptr; #endif struct commandsmember_struct *next; } commandsmember; ../include/objects.h:180:2: error: ‘command’ does not name a type. I think it is C++'s rule C++11 3.3.10/1: "A name can be hidden by an explicit declaration of that same name in a nested declarative region or derived class." So I came with that patch which seems to be the best way to get both gcc and g++ happy. --- <a href="http://objects.h.org">objects.h.org</a> 2012-08-12 17:46:35.000000000 +0200 +++ objects.h 2012-08-12 18:00:24.000000000 +0200 @@ -177,7 +177,7 @@ typedef struct commandsmember_struct { char *command; #ifdef NSCORE - command *command_ptr; + struct command_ptr *command_ptr; #endif struct commandsmember_struct *next; } commandsmember; jfr
