On windows Server 2012 I have installed Visual Studio 2015. Now I have to build Visual Studio C++ 6 based working project in VC++ 2015 but it show various errors and warnings like:

I didn't see any option in configuration manager for VC++6.

I think there may be some other configuration options but don't know much about that. Let me know if any one can help for it.

Further, I have to re-use code and build application using VS Studio 2015 cross platform IDE for android and IOS phones

So how to upgrade VC++6 code that should be compatible to latest version of VC++.

No magic bullet.

That comment from @zeromus sums it up pretty well. You are skipping three major C++ language revisions and seven major Visual Studio releases. VS6 had a C++ compiler that was rather notoriously buggy and non-standard conforming, the end of line for the then-current codebase. VS2002 was a drastic rewrite. That happened again in VS2015, a total rewrite of the front-end to get it to conform with the C++11 and C++14 standards.

for android and IOS phones

You then don't use the MSVC++ compiler at all. VS2015 includes Clang to get that job done, its driver is alpha quality right now and does a pretty shoddy job of mapping project properties onto Clang compile options. One of the first obstacles you are bound to run into is that it does not support pre-compiled headers yet. And of course you'll have to get rid of any Window-isms in your code, you can't include any SDK headers.

No magic bullet, you'll have to start at the top of the Error List. If you get stuck then click the Ask Question button and ask about the specific code fragment that does not compile and quote the exact error message.

Select project in Solution explorer, right click - Properties. C/C++ > Preprocessor.

Repeat this step for all configurations / all platforms, by changing configuration (Debug / Release) / platform (x86 / x64) from top dropboxes, and saving configuration for each configuration / platform.

Edit preprocessor definitions. Add following define '_CRT_SECURE_NO_WARNINGS' - it will disable function compatibility warning.
