By default it installs the headers /usr/local/include/cjson and the libraries to /usr/local/lib. It also installs files for pkg-config to make it easier to detect and use an existing installation of CMake. And it installs CMake config files, that can be used by other CMake based p...

In a C# 2008 application I am getting the error message "Object reference not set to an instance of an object." The line of code that is causing this to occur is the following: public eDataContext() : base(ConfigurationManager.ConnectionStrings["DEVConnectionString"].ConnectionString,...
The concept of a function object is also introduced and illustrated. Function objects allow us to provide alternative semantics for operators used with the generic algorithms, such as the equality or the less-than operator. The algorithms themselves are detailed, with an illustration of their use,...
When declarations in an Objective-C header file refer to a Swift class or protocol that comes from the same target, importing the generated header creates a cyclical reference. To avoid this, use a forward declaration of the Swift class or protocol to reference it in an Objective-C interface...
