I have work with my application, and now, after a correct build I cannot connect to LPCLink, the console write :

No symbol "new" in current context.
set remotetimeout 60000
set mem inaccessible-by-default off
mon ondisconnect nochange
mi_cmd_var_create: unable to create variable object
mi_cmd_var_create: unable to create variable object
Note: automatically using hardware breakpoints for read-only addresses.

Please help me

There is nothing wrong in what you have posted. These are all normal messages. Why do you think you can't connect?

Again, I don't see anything wrong in the messages.

I notice from the log that you are debugging an LPC1758. Therefore, I conclude that you are trying to debug one of your own boards. Can you confirm that is what you are doing? If so, have you correctly wired up the SWD debug signals on the target board?

Yes I work withoy problem with LPCLINK and my board from about two week !
Now, I cannot start the debug, if I open mannualy the debug windows, the play button it isn't enabled, like in the attached jpg file.
I have checked the connection between lpclink and board, and tried to use a simple example program, but does not work!
It is possible that I have inadvertently changed a parameter that is causing this problem?

Thanks for helping

There is no 'play' button because the application hasn't hit the first breakpoint. My guess is that it has hit an exception somewhere in the startup code. To find out what it is doing, just hit the 'Pause' button - it will show what code it is executing.

To find out where it is going wrong, you need to change the initial breakpoint to the reset handler (ResetISR by default) and then single step through the code. See this for details:
http://lpcxpresso.code-red-tech.com/LPCXpresso/node/48

Just to re-iterate, there is nothing wrong with LPC-Link or the debugger. It is your code that is causing this.
