`

i found solution problem. included <net/if.h> before other includes suggested. doesnt solve problem. still same error.

my ../../include/processors/chat/forging.h:9 looks below

`

 9  #include "processors/chat/ms_chat.h" 10  #include <string> 11  // chat 12  #include <vector> 13  #include <gtcpp/mtlock.h> 14  #include <map> 15  // 16  #include "env/genericmapper.h" 17 18  using namespace std; 

`

then /rtcigp/run/pd/ace/6.0.7_x86/64opt/include/ace/os_include/net/os_if.h:28 looks follows

`

27  #if !defined (ace_lacks_net_if_h) 28  #  include /**/ <net/if.h> 29  #  if defined (ace_has_net_if_dl_h) 30  #    include /**/ <net/if_dl.h> 31  #  endif /* ace_has_net_if_dl_h */ 

`

the peculiar thing code compiles without fuss in solaris cc. problem pops out when compile gcc.

am missing here? should there changes made in code when changing gcc cc. or bug in gcc compiler has been fixed in later versions?
