Hello,
I am currently in the process of developping a Tizen Native Service which depends on a portable homemade C++ library. This library includes iostream in some of it's debug capabilities.
However, I am unable to build even the smallest program in Tizen Studio which includes both thread and iostream:
Take this sample program:
#include <tizen.h>
#include <service_app.h>
#include "service.h"
#include <iostream>
bool service_app_create(void *data)
{
// Todo: add your code here.
return true;
}
void service_app_terminate(void *data)
{
// Todo: add your code here.
return;
}
void service_app_control(app_control_h app_control, void *data)
{
// Todo: add your code here.
return;
}
int main(int argc, char* argv[])
{
char ad[50] = {0,};
service_app_lifecycle_callback_s event_callback;
app_event_handler_h handlers[5] = {NULL, };
event_callback.create = service_app_create;
event_callback.terminate = service_app_terminate;
event_callback.app_control = service_app_control;
return service_app_main(argc, argv, &event_callback, ad);
}
When using the wearable 2.3.2 arm GCC-4.9 tool chain, I get the following error when the linker is invoked:

This issue was encountered with Tizen Studio 1.2 with the wear-2.3.2 package. I cannot find which library is supposed to provide the clock_gettime symbol, but it does not seem to be included in the system libs.
This same program works without any issue when using the gcc 4.6 tool chain, but I find it strange that I cannot use the latest version of the libs for my project.
