“No symbol table info available”

今天在用Code::Block時遇到了"No symbol table info available",不知道為什麼錯了，然後就上官網看debuger的說明。

它上面有這麼一段話：

 

In the Debug menu, under "Debugging windows", select "Watches". You can use this window to examine the function arguments and local variables. Alas, this turns out to not be very useful, because our program is actually stopped inside the operator>> function, and we don't have access to the local variables inside there. (Hence the message "No symbol table info available.).

• It appears to be zero, which tells us that the crash occurred on the attempt to read the very first word.

 

In the editor window, though, double-click or drag your mouse to highlight "numWords". Right-click on that and select "Watch 'numWords'". The current value of numWords appears in the Watches window.
