Hi,
I want to disable compiler warning C4482 (nonstandard extension used:
enum 'enum' used in qualified name)

I can disable the warning using this,

#pragma warning(push)
#pragma warning(disable : 4482)

//My code here

#pragma warning(pop)


But this is just for a single file. How can I disable this error at the
project level?? I guess there are some compiler switch for it.


Secondly, will this have any effect on the project?

Regards,
Ashutosh

/wd4482 on the compiler command line will disable that warning. Try typing
cl /? at a "visual studio" command prompt to see all the compiler command
line options.

Other than suppressing the warning, no.

-cd

Hello Ashutosh,

Suppose that you are using Visual Studio 2005 to build the VC project. In
order to disable some warning message in the project level, the steps are
as follows:

1. Right click on the project in Solution Explorer, and select "Property"
2. Go to "Configuration Properties" | "C/C++" | "Advanced" | "Disable
Specific Warnings"
3. In the "Disable Specific Warnings" dialog, input the warning ID. The ID
is just numeric part, in our case, it's 4482.
4. Click OK, and re-compile the project.

The setting is saved in your vcproj file:

<Tool
Name="VCCLCompilerTool"
Optimization="0"
PreprocessorDefinitions="WIN32;_DEBUG;_WINDOWS;_USRDLL;TESTDLL_EXPORTS"
MinimalRebuild="true"
BasicRuntimeChecks="3"
RuntimeLibrary="3"
UsePrecompiledHeader="2"
WarningLevel="3"
Detect64BitPortabilityProblems="true"
DebugInformationFormat="4"
DisableSpecificWarnings="4482"
/>

This setting won't have any effect but removing 4822 from warning lists
from the project.

Please have a try and let me know whether this works for you.

Fix the code:

enum foo { bar };
// wrong
foo f = foo::bar;
// correct
foo f = bar;

Enumeration constants 'leak' into the surrounding namespace. If you don't
want that, enclose the enumeration itself in a namespace:

namespace foo {
enum type { bar };
}
foo::type f = foo::bar;

Disabling or ignoring warning doesn't directly affect the outcome, but in
general warnings are a sign of low code quality. Your code above is simply
not portable to other compilers that don't support this extension.

Fix it, it's broken.
