warnings

问题 When you run any rake task with cucumber installed on a machine that doesn't have ANSICON installed, you get the following message: *** WARNING: You must use ANSICON 1.31 or higher (http://adoxa.110mb.com/ansicon) to get coloured output on Windows When running locally I like using ANSICON, but when used within the build server I don't care about that - and I don't want to see that warning there. Is there a way to get rid of it? 回答1: You can actually remove the warning itself. I do not like

问题 I'm seeing numerous mentions on the web of a -Wformat=2 option to Clang, sometimes alongside the already-known -Wformat (the one that Xcode lists as “Typecheck calls to printf / scanf , although it covers many more string-formatting APIs now). Does this do anything at all? If it does, what, if anything, does it do differently from -Wformat ? Is it useful to have both, or is either one a superset of the other? 回答1: If it does, what, if anything, does it do differently from -Wformat? It's

问题 i've activated warnings with doxygen WARNINGS = YES WARN_IF_UNDOCUMENTED = YES WARN_IF_DOC_ERROR = YES WARN_NO_PARAMDOC = YES But undocumented methods like this one: void AnimationManager::setAnimationTimeStep( double timeStep ) { ... } Do not throw any warning during doxygen generation. Is there any way to display warning in this situation ? Same problem with undocumented return , for example /** * @brief brief description */ bool AnimationManager::hasAnimationTimeStep( ) { ... } Does not

问题 I'm having trouble finding any information regarding the following warning when linking a dynamic library: In function `MyClass::myfunc()': MyClass.cpp:(.text+0x14e4): warning: memset used with constant zero length parameter; this could be due to transposed parameters Here is an excerpt of myfunc : void MyClass::myfunc() { vector<Variable*>::const_iterator it; for (it = m_vars.begin(); it != m_vars.end(); ++it) { if ((*it)->recordme) { MyRecord* r = new MyRecord(*it); initMyRecord(*r); m

问题 I keep getting this error about 20 times in my wordpress blog about the same line of code. Here is the line of code that keeps getting the error. if ( preg_match( '/' . $id_base . '-([0-9]+)$/', $widget_id, $matches ) ) $number = max($number, $matches[1]); What could be wrong? 回答1: Your regex will break if the string $id_base has a / in it as you are using / as the regex delimiter. To fix this use preg_quote on $id_base as: if (preg_match('/'. preg_quote($id_base,'/').'-([0-9]+)$/', .....) {

问题 Suppose that you have a bunch of projects in your Eclipse workspace. Some are Java projects, some may be CDT projects, others may come from third party plugins such as TeXlipse or EPIC. You strive long and hard to produce quality code, yet in one specific project you have a couple of warnings, through no fault of your own - warnings that propagate up the chain to your working set and poke you in the eye. Is there a general way in Eclipse 3.7 to tell the IDE that it should ignore (and be quiet

问题 Using eclipse 4.2 with Java 7 and trying to implement the following method of the List interface i got a warning. public <T> T[] toArray(T[] a) { return a; } The warning says : The type parameter T is hiding the type T Why ? How can i get rid of it ? 回答1: The List interface is also generic. Make sure that you are not also using T for the generic type in your class. Note that in http://docs.oracle.com/javase/6/docs/api/java/util/List.html, they use "E" for the class generic parameter and "T"

问题 Is it possible to treat warnings as errors in a Makfile (and thus exit before Makefile proceeds) Furthermore, is it possible to filter out which warning yields an error? My use case: I want to use --warn-undefined-variables in combination with this so that Makefile will exit when a variable is undefined, which is a very common source of error. Obviously I don't want to manually check for each variable as this is error-prone/tedious. I couldn't find anything on this, but it's a pretty
