I've created a Qt-based network library for use with applications that are not running a Qt event loop, and which are not necessarily otherwise Qt applications. This was made possible by creating a QCoreApplication instance in a thread per the answer from Is it possible to create local event loops without calling QApplication::exec()? This works perfectly, but it makes Qt upset (I presume it's worried that I'll try to manipulate a GUI outside of the main thread which wouldn't work, but I'm not), and so it prints a warning: WARNING: QApplication was not created in main() thread . I'd like to

I have some code for testing that i added upfront the rest of the code, so the rest would never be reached in the test. Since i have warning level 4 set, this results in an c4702: unreachable-code warning I tried disabling like this: //do something return 0; /*-------------------------------------------------------------------------*/ #pragma warning(disable: 4702) //real code but the compiler still moans. And because i have set to treat every warning as an error, this won't compile... I am using Visual Studio 2012 Premium... Any help would be gladly appreciated. You maybe just need to place

I tried modifying the php.ini file (error_reporting = E_ALL & ~E_DEPRECATED), but with no result. There's an older TYPO3 project which I would like to examine, and all these warnings are really annoying.. Thanks in advance. I'm not sure if this will work on your version of Typo3 but try setting the following options in the typo3conf/localconf.php or via the Install Tool. $TYPO3_CONF_VARS['SYS']['displayErrors'] = '0'; // or '-1' to see other errors $TYPO3_CONF_VARS['SYS']['errorHandlerErrors'] = 22519; // E_ALL ^ E_DEPRECATED ^ E_NOTICE (everything except deprecated-msgs and notices) $TYPO3

In porting a large piece of C++ code from Visual Studio (2008) to Xcode (4.4+), I encounter lines such as: UNUSED_ALWAYS(someVar); the UNUSED_ALWAYS(x) (through UNUSED(x) ) macro expands to x which seems to silence Visual C++ just fine. It's not enough for Clang however. With Clang, I usually use the #pragma unused x directive. The UNUSED_ALWAYS and UNUSED macros are defined in an artificial windows.h header which I control that contains a number of utilities to help Xcode compile Windows stuff. Is there a way to define UNUSED(x) to expand to #pragma unused x ? I tried this, which Clang fails

I'm trying to raise a DeprecationWarning , with a code snippet based on the example shown in the docs. http://docs.python.org/2/library/warnings.html#warnings.warn Official def deprecation(message): warnings.warn(message, DeprecationWarning, stacklevel=2) Mine import warnings warnings.warn("This is a warnings.", DeprecationWarning, stacklevel=2) is None # returns True I've tried removing the stacklevel argument, setting it to negative, 0, 2 and 20000. The warning is always silently swallowed. It doesn't issue a warning or raise an exception. It just ignores the line and returns None . The docs

I'm getting the user's location through Location location = LocationServices.FusedLocationApi.getLastLocation( mGoogleApiClient); This line of code is inside a method and before calling this method I do check for Android run time permissions. Only if the permission is available from the user then I call this method. Code is working perfectly. The problem is that Android Studio still shows an error on this line not recognising that I've already checked before calling this function. Call requires permission which may be rejected by user: code should explicitly check to see if permission is

I am defining some functions to be used as callbacks and not all of them use all their parameters. How can I mark unused parameters so that the compiler won't give me warnings about them? bashor With the @Suppress annotation You can suppress any diagnostics on any declaration or expression. Examples: Suppress warning on parameter: fun foo(a: Int, @Suppress("UNUSED_PARAMETER") b: Int) = a Suppress all UNUSED_PARAMETER warnings inside declaration @Suppress("UNUSED_PARAMETER") fun foo(a: Int, b: Int) { fun bar(c: Int) {} } @Suppress("UNUSED_PARAMETER") class Baz { fun foo(a: Int, b: Int) { fun
