问题 As the question states, what exactly are the implications of having the 'implicit declaration of function' warning? We just cranked up the warning flags on gcc and found quite a few instances of these warnings and I'm curious what type of problems this may have caused prior to fixing them? Also, why is this a warning and not an error. How is gcc even able to successfully link this executable? As you can see in the example below, the executable functions as expected. Take the following two

问题 Take this little example code: struct Test{ operator int() const{ return 0; } }; Test test(){ return Test(); } int main(){ int arr[10]; arr[test()] = 5; } Compiling under Visual Studio 2010 with /W4 generates said warning. Interestingly, if I add but a simple default constructor, the warning suddenly vanishes. Also, it only works in that constellation. If I remove the function call or don't return a user-defined type, the warning disappears. Also, as expected, GCC doesn't produce such a

问题 This question already has answers here : Webstorm 7 cannot recognize node API methods (5 answers) Closed 1 year ago . Trying to fix WebStorm v11.0.4 warnings in JavaScript. Lots of unresolved variable or type errors for custom types in SailsJS application, such as this one: I already enabled Node.js in WebStorm. Also, don't know if it is linked, but cannot see "Node Globals" as a library to enable (see pictures below). Now, I'm clearly not a JavaScript pro. There is a file called DataService

A warning which doesn't show up in the R CMD check results: 1 warning or 0 warnings?

问题 I'm building an R package under Windows 10 with RStudio 1.0.136 and get a warning about qpdf (see How to build qpdf on Windows? for more details about this issue). But and the end of the checks, the number of warnings is shown to be 0. So I wonder if there is one or no warning that has to be solved before I can submit the package to CRAN? Here is the last part of the checks: ... checking for unstated dependencies in examples ... OK WARNING 'qpdf' is needed for checks on size reduction of PDFs

How to define (non-method) functions in header libraries

问题 When writing a header library (like Boost), can one define free-floating (non-method) functions without (1) bloating the generated binary and (2) incurring "unused" warnings? When I define a function in a header that's included by multiple source files which in turn is linked into the same binary, the linker complains about redefinitions. One way around this is to make the functions static, but this reproduces the code in each translation unit (BTW, can linkers safely dereplicate these?).
