You seem to be saying that the code you are showing doesn’t actually produce the compiler error that you are having a problem with. So we can only guess. Here are some possibilities: You could have forgot to include problemclass.h from the file where you are using ProblemClass. You could have misspelled the name of … Read more
Generic functions in TypeScript act as a function representing every possible specification of its generic type parameters, since it’s the caller of the function that specifies the type parameter, not the implementer: type GenericFunction = <T>(x: T) => T; const cantDoThis: GenericFunction = (x: string) => x.toUpperCase(); // error! // doesn’t work for every T … Read more
I’ve been facing the same issue with java 8 (ubuntu 16.04), trying to compile using mvn command line. I verified my $JAVA_HOME, java -version and mvn -version. Everything seems to be okay pointing to /usr/lib/jvm/java-8-openjdk-amd64. It appears that java-8-openjdk-amd64 is not completly installed by default and only contains the JRE (despite its name “jdk”). Re-installing … Read more
Seeing from your G++ version, you need to update it badly. C++11 has only been available since G++ 4.3. The most recent version is 4.7. In versions pre-G++ 4.7, you’ll have to use -std=c++0x, for more recent versions you can use -std=c++11.
As Selman22 said, you are overriding the default object.Equals method, which accepts an object obj and not a safe compile time type. In order for that to happen, make your type implement IEquatable<Box>: public class Box : IEquatable<Box> { double height, length, breadth; public static bool operator ==(Box obj1, Box obj2) { if (ReferenceEquals(obj1, obj2)) … Read more
make_unique is an upcoming C++14 feature and thus might not be available on your compiler, even if it is C++11 compliant. You can however easily roll your own implementation: template<typename T, typename… Args> std::unique_ptr<T> make_unique(Args&&… args) { return std::unique_ptr<T>(new T(std::forward<Args>(args)…)); } (FYI, here is the final version of make_unique that was voted into C++14. This … Read more
Use #include <windows.h> instead of #include <windef.h>. From the windows.h wikipedia page: There are a number of child header files that are automatically included with windows.h. Many of these files cannot simply be included by themselves (they are not self-contained), because of dependencies. windef.h is one of the files automatically included with windows.h.
Starting from Visual Studio 2017 another solution to keep using the AssemblyInfo.cs file is to turn off automatic assembly info generation like this: <Project Sdk=”Microsoft.NET.Sdk”> <PropertyGroup> <GenerateAssemblyInfo>false</GenerateAssemblyInfo> </PropertyGroup> </Project> I personally find it very useful for projects which need to support both .NET Framework and .NET Standard.
Add Another “}” at end of your code you missed one 2.There is another error in your code if((value = “true”)) is not a proper way to check string equality and has syntax error it should be if(value.equals(“true”))
Assuming the question is about Go, e.g. var _ foo.RequiredInterface = myType{} // or &myType{} or [&]myType if scalar as a TLD will check that for you at compile time.
