Hi,
I know there are gcc flags that can turn all warnings into errors.
However, what I'm looking for right now is something to turn a
specific warning into an error while leaving other warnings alone:
warning: cannot pass objects of non-POD type 'class MyClass' through
'...'; call will abort at runtime
Translation: "I have no idea what to do, but I'll compile it anyway."
IMHO this really should be an error and not a warning - is there any
way to get this behavior?
I asked about this once before and never got an answer. If you are
looking to fix all of the current warnings you have for this, then do
a full build after cleaning, select the Errors & Warnings group in the
project window (I'm using the default layout), then use the Search
field to filter the warnings. I don't know of a way to guard against
adding this type of code in the future by elevating it to an error.
I had this "warning" turn up in a kext. In that case, "abort at
runtime" translates to "panic the system". :) Wasted a good day or
two finding that one. This was way back in the Project Builder days,
and I had since all but forgotten about it. Then when I was working
on Universal Binary conversion, at some point someone else re-enabled
the code that was crashing (ironically, it was just a debug printf
that was passing a non-POD type as one of the varargs!). This
"warning" was lost in the morass of other warnings, which yes I
legitimately need to clean up, but that was lower priority than just
getting the Intel build working... so I spent another good day or two
tracking down the same bug.
Jim
