cross-platform

问题 I am bit confused with the terms of cross platform and cross compiler. Let me be first clear about the cross platform. When people talk about cross platform it means the architecture of the CPU, i.e, X86 and X64 ? or the OS i.e windows 32 bit or Windows 64 (server or desktop)? UNIX doesn't have different flavours like 64 bit or 32 bit. Why so? .NET and java is cross compiler language, what it means? When the program is compiled in .NET, we have to choose the option like X86, X64 or Any CPU.

This is not surprising, as the dll/so files of external dependencies are not placed in the output directory( bin in visualization below). One of the dependencies that are

问题 I'm creating an app using xamarin Forms (multiplatform), I'm using a Navigation page, but I want to change the arrow ("<-") to text ("back") Do you know how could i do it?
