warnings

问题 Hi I have iMac with OS X Yosemite version 10.10.3 and I've installed the last Xcode 6.3 beta 2 with Swift 1.2 and when I try to Run the App I receive: Check dependencies Unable to determine compiler to use - the abstract compiler specification is missing from this Xcode installation. and everytime when I open my project with Xcode I receive a warning: warning: no rule to process file '/Users/Bogdan-iMac/Desktop/My App/My App/My_App.xcdatamodel' of type wrapper for architecture x86_64 and I

问题 I have two classes, GenericList and SpecificList , where SpecificList inherits from GenericList . GenericList implements IEnumerable<GenericItem> and SpecificList implements IEnumerable<SpecificItem> . SpecificItem inherits from GenericItem . I have to implement GetEnumerator in both GenericList and SpecificList since they implement IEnumerable<T> . In GenericList , it's easy enough, I just return the enumerator for the underlying List<T> : public IEnumerator<GenericItem> GetEnumerator() {

问题 I've got this formula that generates the correct data: var avgWeeklyDeliveriesCell = (Range)_xlSheetDelPerf.Cells[curDelPerfRow, AVG_WEEKLY_DELIVERIES_COLUMN]; avgWeeklyDeliveriesCell.Value2 = string.Format("=ROUND(AVERAGE(C{0}:I{0}), 2)", curDelPerfRow); The problem is that it overthinks/micro-manages matters, and wonders if an adjacent cell (the one to the left, I presume, "Total Orders") should be included in the formula. Specifically, if I click on the green triangle, a "!" glyph pops out

问题 In my code I have a lot of variable <<= 1; sentences where variable is of type uint16_t. The compiler is spitting a warning saying conversion to 'uint16_t' from 'int' may alter its value [-Wconversion] How can I resolve it? I could use a long-form notation like variable = (uint16_t)(variable << 1) - but I'd like to keep the short notation. 回答1: Based upon my reading of the standard, you can not get away from this warning for this reason: uint16_t foo; foo <<= 1; is equivalent to uint16_t foo;

问题 I am using Eclipse Juno for a Java project. I have activated different warnings in my workspace settings. Furthermore I use Checkstyle with a defined rule set for each project. The problem I am facing now is that Eclipse shows warnings (not sure, if Checkstyle or Java warnings) and does not update the warnings anymore, when I change code. E.g. I have warnings in empty lines referring to code in other lines. I already tried the following things: Refresh with F5 Building the projects Project

问题 I am trying to compile my project with an open source library GDCM on Visual C++ 2010 on Windows 7 64 bits. I have included required .lib files (gdcmDSED.lib and gdcmMSFF.lib) in my project, however, the compiler complains back more than 100 unresolved external errors. But I see some patterns in the errors. Here: 1>gdcmDSED.lib(gdcmSequenceOfItems.obj) : warning LNK4049: locally defined symbol ??1?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAE@XZ (public: __thiscall std:

问题 How can I see a warning again without restarting python. Now I see them only once. Consider this code for example: import pandas as pd pd.Series([1]) / 0 I get RuntimeWarning: divide by zero encountered in true_divide But when I run it again it executes silently. How can I see the warning again without restarting python? I have tried to do del __warningregistry__ but that doesn't help. Seems like only some types of warnings are stored there. For example if I do: def f(): X = pd.DataFrame(dict

问题 Given: if ($variable = get_variable('variable')) { // ... } The *$variable = get_variable('variable')* throws an 'Assignment in condition' warning in Zend Studio. I understand what the warning means, but does anyone know what the rationale behind it is? Is it merely coding conventions, a matter of readability, etc.? 回答1: This is a very common warning issued by IDEs/compilers in most languages that allow this construct: since = (assignment) and == (comparison) are very similar, and comparison

问题 I created a class FormInfo = class (TComponent) private FLeftValue : Integer; FTopValue : Integer; FHeightValue : Integer; FWidthValue : Integer; public constructor Create( AOwner : TComponent; leftvalue : integer; topvalue : integer; heightvalue : integer; widthvalue : integer); protected procedure GetChildren(Proc: TGetChildProc; Root: TComponent); override; function GetChildOwner: TComponent; override; //procedure SetParentComponent(Value : TComponent); override; published property

问题 This is the first time that I met the following warning "Warning 21: this statement never returns (or has an unsound type.)" and I don't have an idea how to fix it. let display_committers_stats response = match response##readyState with | XmlHttpRequest.DONE -> begin match response##status with | 200 -> Js_client_ui.create_menu_tabs "GitSearchTabs"; let l = Json_parser.get_commits (Js.to_string response##responseText) in let values = Json_parser.group_commits_by_user l |> List.map (fun
