11 Mar 2020 by Richard MacCutchan
The message is quite clear. You are trying to use a macro (I assume) that does not exist. Check the documentation at GtkLabel: GTK+ 3 Reference Manual[^] for the correct syntax.
11 Mar 2020 by markkuk
You can change the contents of a label with the gtk_label_set_text()[^] function and set up a callback function that gets called each second with g_timeout_add_seconds()[^]. Your callback function should read the temperature using the tempRead()...

11 Mar 2020 by CPallini
Have a look at this page Asynchronous GUI Update in GTK[^], see gdk_threads_add_timeout example. Note you may use sprintf[^] (just like you've used printf) to set the buffer that, in turn, will be used to update the label.
10 Mar 2020 by Richard MacCutchan
In your main program loop you should sample the temperature at fixed intervals, or use some event handler to capture changes. Whenever a new temperature value is captured you pass that to the GTK function to updtate the display.
