Compiling error with unsigned and int

Question

I'm using Eclipse and xCode to develop in C++.

The problem is in Eclipse I used the following statement:

unsigned asdf = -1;

In eclipse it worked fine, but in xcode is not letting you compile. How can I specify in Eclipses's settings to not let me compile if there is something like this?

Ops, sorry. It doesn't let you compile. – user3468999 Aug 28 '14 at 10:07 — user3468999, Aug 28 '14 at 10:07

I believe this warning is -Wsign-conversion being used by Xcode. Obviously you are compiling under Eclipse without this warning. This is a good warning (most are) so the better solution is to fix the code and up the warnings in Eclipse to match Xcode.

I am not near my Mac at the moment so I cannot show you a screenshot of Xcode, however you should be able to find this warning and disable it in your project settings, if you don't wish to fix the code.

That is what I want. Match the warnings. But I don't know where is it in Eclipse. – user3468999 Aug 28 '14 at 13:05

The error should be the fact that you don't declare what the type of variable, try

unsigned int asdf = -1;

No, that's not the issue. – trojanfoe Aug 28 '14 at 12:23
