How does one disable the warning "warning: converting to 'int' from
'float'".
I know I could cast, but there are too many. :(
Just cast. If it's your intention to convert a float to an int, you
should
have a cast there to show that; otherwise the code isn't clear.
I agree. But adding thousands of casts really doesn't appeal to me.
It's an old codebase.
(Having not seen your code, of course, this is all very general
advice.
Maybe it doesn't apply to you for some reason, or maybe you really
have
your heart set on turning off this warning rather than changing the
code.)
So is it really impossible to turn off this warning? gcc has so many
options! But none for this one? :( I don't want to have to
disable all
warnings.
I'm assuming that this is C++ code (or ObjC++ code), since I can't see
where this warning would come from otherwise, in which case a quick
review of the GCC code reveals that there is indeed no way to disable
this warning (short of changing the file gcc/cp/call.c, that is).
It should be relatively easy to add an option to GCC to control this
warning if you *really* need to disable it. Otherwise you could adopt
the approach I saw a while back, which was to always run the compiler
through a Perl script that filtered out unwanted warnings. (I can't
say I'm a huge fan of that, but it might be a good option for you, which
is why I mention it).
