Common SDL project for Visual C++ cross platform development - c++

I'm attempting to use Visual C++ cross platform features to write an SDL 2 app for Windows, Windows Universal, iOS, Android and Linux. I have one project for each platform now I want to abstract the SDL stuff to a common project that each platform project will reference with each project supplying the appropriate SDL libs for the platform through the linker.
Is there a project type in VS that actually allows me to do this? I was hoping the shared items project would do the trick, but I doubt thats the one. There does appear to be some form of shared library for iOS and Android, but it doesn't look like that extends to Linux and Win32.
Thanks,

To make a successful cross-platform application with SDL2, you should, in first place, use a compiler that's available on both platform. Because, you will need to compile a binary for each platform. SDL2 seems to support IOS and Android out of the box, but I don't know how deployment is done for the mobile OS. You can still use Visual Studio with CMake or a Makefile and use another compiler instead of Visual C++ to support a cross-platform build, like g++ (mingw32 on windows) or Clang.

Qt - C++ Graphical application in visual studio

I want to create graphical application (drawing and moving squares and so) using C++. I was suggested to use Qt library for this. I am windows user and I use Visual Studio 2013 for developing C++ (console) apps. So I typed Qt download into google hoping to find some package of DLLs, libs, headers or something like that so I could include headers and link libraries with my code. But all I found was IDE Qt Creator (which I do not want) and Qt Visual Studio plugin (which I downloaded, but it still requires whole IDE to work). So my question is - How can I develop graphical application (no forms, just "canvas" to draw on with some mouse/keyboard support) using Qt library, C++ language and Visual Studio IDE, without requirement of downloading tons of GBs for IDE or plugins I do not want, with insurance that application would be easily deployable on most common operating systems.
The reason I do not want Qt creator IDE is simple -- There is a chance for this to be semester project and will be reviewed by teacher without any extra IDEs. (I'll send him just VS project/generated Makefile and Qt libraries with headers)
Thanks for clarification.
The short answer is: you cannot. You need Qt SDK, which comes with Qt Creator.
Qt comes with qmake build system and it does not require any IDE to compile and run the application. You can write in any IDE you want and compile anywhere, where Qt SDK and compiler is available.
If you want to provide the application to your teacher, he must have Qt SDK too to compile it. There is no way around this. And better test the application in the target environment. Writing portable applications is not a trivial task - if you hardcode paths like C:\QtSDK\path\to\something, there is little chance to run it under Linux without any changes.
If you cannot expect any SDK on a teacher's computer, you have few options:
convince her to install necessary tools
ask her what tools are permitted and stick with them
bring your own computer for final evaluation

Platform for c++ cross compile application

Currently, we are using MS Visual Studio and .NET to develop out applications on Window. We are in the process of porting the application to other OS (Linux, Android...etc) and want to get rid of MS Visual Studio and .NET stuff (they have been a pain to work with).
Is there any good development platform that you would recommend?
Thanks,
ABS
I would port the Visual Studio's solution/project files to CMake (in the downloads list you can get binaries for Windows and Linux), which allows you to generate project files for different platforms, allowing cross-toolset development. Eg:
On Windows, running CMake would detect Visual Studio and would generate solution and project files accordingly.
On Linux: running CMake would find, for instance, gcc or g++ and would generate makefiles accordingly.
I have not tried it, but for android's NDK there's this: android-cmake
[UPDATE Information on gcc/make for windows]
If you want to drop Visual Studio completely, you can try to set up the gcc/make toolchain for Windows with MinGW - Minimalist GNU for Windows, and port your solution/project files to makefiles.
Moving from Windows to other OS'es may shock you at first, but with time you'll get used to it: You do not need a "platform" or "IDE" per se.
What you will need, is cmake, gcc/g++, a decent text editor and perhaps a debugger frontend.
Optionally you may find ctags useful, Doxygen, an svn repo and a profiler (such as Valgrind/KCachegrind).
I am unaware of how exactly you can port .net stuff to C/C++ (other than re-writing from scratch).
Linux and OSX have many similarities, so porting from one to another should not be that hard. Android is a different story, although C++ for android has become a possibility.
The closest thing to what you are looking for, would probably be Eclipse or Netbeans, but again, the simpler you keep those things, the better IMHO.
As to getting rid of .NET, If your .NET code base is not in managed C++ in its entirety, I would try out Mono/Xamarin with Xamarin Studio IDE first before embarking on a full port of .NET code base to standardized C++.

Compile A MSVC++2010 Project So It Can Run On Ubuntu

I have a MSVC++ 2010 project. All the libraries it's using are cross platform (SDL, OpenGL and FLTK).
Obviously, all I have to do right now is press the debug button and it will compile a nice old .exe for me which can now run on Windows, as long as the DLL files are with it.
I had thought before that if you use cross platform libraries, then the generated .exe would run fine on Ubuntu too. I recently found out that this is not possible, and that the program must be compiled in a special way to run on a certain platform.
Is it possible to compile my project in this magical way with MSVC++ 2010 so that it can run on a Ubuntu computer? If so, then could you please answer my question with some clear steps as to what I should do to compile it this way, keeping in mind I'm new to how all this cross platform stuff works?
EDIT:
If I cannot compile a MSVC++ 2010 project for Ubuntu, is there an IDE I could use that could compile the project for both Windows and Ubuntu?
Thanks.
I suggest you use QT. http://qt.digia.com/
It's probably the best cross platform IDE that can let you compile for Windows, Mac and Linux(ubuntu) systems.
Nope, not possible. While the binary code corresponding to the program can be portable, that's not enough. Executable formats on various file systems are different and not compatible. The executable format is essentially a packaging of the binary data and wrapping it with a header that the target file system understands. In order to produce executables for Ubuntu, the linker must support it. MSVC++ doesn't support Linux formats.

Can a single eclipse C++ project link different libraries differently for different platforms?

I have a C++ eclipse project that I would like to easily compile In Windows and OSX.
The project is currently using an automatically generated makefile.
The libraries that I need vary depending on the platform.
In osx I'm using the CoreMidi, CoreAudio, and CoreFoundation frameworks.
In Windows I'm using the winmm.lib and multithreaded libraries.
What's the simplest way to link different libraries/frameworks depending on the current platform?
I'm currently using the gcc toolchain on OSX. Should I start using the cross compile toolchain?
Should I have two projects. One for working in windows, and one for osx, checking them both in to version control?
Should I write a custom makefile instead of using the automatically generated option that has different g++ arguments depending on the platform?
I personally had the same goal for a project and came to the conclusion the Qt framework was the best thing for me. It handles multiple languages, unicode strings, XML, network communications, native looking user interfaces, console applications: it can do an AWFUL lot.
However, as Paul pointed out, you really have to plan it from the start.
Qt does a good job of abstracting the platform away (in a module called QtCore) allowing you to write vanilla C++ code, or you can chose to include some Qt C++ language extensions which a Qt helper application called the moc (meta object compiler) creates vanilla C++ from, which can then be compiled by most common C++ compilers.
It also has a nifty cross-platform makefile generator called qmake which works on project files to create normal make files for the platform its running on.
Off the top of my head at least Windows XP & 7, OSX 10.4, 10.5, 10.6 are supported currently. But note that OSX Lion is (as of writing) not officially supported but I suspect it will be in the next release.
Based on your description, I am not sure you can easily make it cross-platform. Even without using third-party library, you have to provide separate code for osx and windows. Most of time, they design the system as cross-platform first. It's really hard to make an existing project on single-platform to cross-one. If you have the cross-platform requirement, you'd better design in that way first and rewrite from scratch.
Even though Eclipse can run fine on both OS X and Windows, it is not designed to be used in this way.
The best way to do it is to use separate IDE projects for each platform. This this is the easiest way to have unique compilation settings for multiple platforms.
Yes, you can use two eclipse projects. Alternatively, it's not unusual to have a X-Code project for OSX, and a Visual Studio Project for MS Windows.

Cross-platform C++ IDE that also supports Objective-C?

I have a few projects where most of the code is written in platform-agnostic C++, with a relatively thin platform abstraction layer for each supported platform. For most platforms this abstraction layer is also written in C++, but for iOS and OSX it also contains some Objective-C code. For this reason, I have Xcode projects for the iOS / OSX builds, and Visual Studio projects for Windows, but I'm a bit tired of having to maintain multiple project files.
It would be so nice to only have one cross-platform IDE, one project file for that IDE, then just add all source files to that, and make some of them included in the build only in certain configurations. But for that I'd need an IDE that runs on multiple platforms (Windows, OSX, preferably linux too), and supports not only C++, but Objective-C source files as well. Is there such a thing?
You can try QtCreator. It's a cross-platform IDE developed for Qt but it supports Objective-c too:
