compiler-warnings

I've got some code that uses type-punning to avoid having to call a member "object"'s constructor and destructor unless/until it's actually necessary to use the object. It works fine, but under g++ 4.4.3, I get this dreaded compiler warning: jaf@jeremy-desktop:~$ g++ -O3 -Wall puns.cpp puns.cpp: In instantiation of ‘Lightweight<Heavyweight>’: puns.cpp:68: instantiated from here puns.cpp:12: warning: ignoring attributes applied to ‘Heavyweight’ after definition puns.cpp: In destructor ‘Lightweight<T>::~Lightweight() [with T = Heavyweight]’: puns.cpp:68: instantiated from here puns.cpp:20:

apologies in advance if i use poor terminology. when i compile a C++ app under gdb and use printf() it gives me awesome warnings relating to the consistency of the format string and the arguments passed in. eg, this code: printf("%s %s", "foo"); results in a compiler warning "too few arguments for format", which is super-useful. it will also give warnings about format string type vs. argument type. it must have inspected the format string and compared that against the supplied argument types. - is this sort of compile-time introspection something which can be added to ordinary source code, or

Can someone help me to turn off warnings in Xcode 4 that I'm getting from subprojects? I have three subprojects, with a lot of warnings. The subprojects are provide by my customer's R&D studio. I would like to turn off the warnings there, to put all my efforts and attention on warnings in my own code. Is this possibile in Xcode 4? If you're using Xcode 4.2 or later, you can use LLVM compiler setting Inhibit All Warnings in Warning Polices for every subproject you have: A partial solution only: If your subprojects build libraries or bundles that do not have to recompile at every run, you can

For command-line builds, I would like to treat warnings (for example "Constructing instance containing abstract method") as errors. I have not found a dcc32 command line option for this purpose in Delphi 2009. Is there a way, for example using dcc32.cfg, to do this? David Heffernan Like this: dcc32 -W^^CONSTRUCTING_ABSTRACT MyProject.dpr For example, with this program: program MyProject; type TMyClass = class procedure X; virtual; abstract; end; begin TMyClass.Create; end. And here's the output: >dcc32 MyProject.dpr Embarcadero Delphi for Win32 compiler version 24.0 Copyright (c) 1983,2012

When I compile my project with compiler warnings (JDK 1.5) I get a bunch of bad path element warnings: Warning:: [path] bad path element "C:\Users\User\MyJava\common\lib\junit.jar": no such file or directory Warning:: [path] bad path element "C:\Users\User\MyJava\common\lib\jdom.jar": no such file or directory Warning:: [path] bad path element "C:\Users\User\MyJava\common\lib\xerces.jar": no such file or directory Warning:: [path] bad path element "C:\Users\User\MyJava\common\lib\xml-apis.jar": no such file or directory and many more. This is using IDEA 8.1.3. I can't find anywhere in IDEA's

I'm working on a large collaborative C++ project that is both developed and run on various flavors of Linux, OS X and Windows. We compile across these platforms with GCC, Visual Studio C++ and the Intel C++ compiler. As more and more people start developing code for the project, we're starting to see weird errors in compilation and runtime that are specific to particular compilers on particular operating systems. An example of this is implicit inclusion of headers that certain OS/compiler pairs seem to find for you, accidentally overloading a function from a base class in a derived class. My
