Making the 'delete' warnings in gcc into errors

Question

I want to make the following warnings in gcc into errors, however, I failed to find any documentation on which switches control them, including the -fdiagnostics-show-option switch.

The warnings are:

deleteing void * is undefined

and

possible problem detected in invocation of delete operator:
'p' has incomplete type

Answer 1

The [enabled by default] part of the warnings (that you didn't show) indicates that there is no specific warning flag controlling them, so nothing you can use to say -Wno-xxx or -Werror=xxx

With GCC 4.9 you can use -Werror=delete-incomplete to control the second one

Answer 2

您可以使用-Werror标记进行编译，以将警告视为错误。
