making a cross platform program
« on: October 26, 2014, 11:27:13 am »
Hello guys!
I've started learning about making games lately and I choose SFML and c++ for that.
Currently I'm using visual studio 2010. I built a win32 application and it works fine.
The problem is, I don't want to show the console screen together with the sfml window.
Furthermore, I searched a lot in the web but I couldn't find an answer to how compiling the project so the final executable will work in different OS's like Linux.
I hope you can help me with that or give me a reference to some information on thar .
Thank you, Alex.

Go to your project settings -> Linker -> System and set SubSystem to Windows. Also you cannot compile for a different OS. You will need to install Unix and compile your source code on that for it to work on Unix, same with MacOS and Android and whatever else you want to run it on.

Not exactly. Although VMs with native environments are much easier to work with, you can also cross-compile. Cross-compiling is also the easiest for mobile platforms (compiling on a phone is not straight-forward ;)).

I'll be honest and say that I'm not sure what you mean. I know that with Visual Studio you can compile for Windows on 32 and 64 bit (If your OS is 64 bit) but I wasnt aware you could cross compile from a single OS. Of course VMs are a good way to compile on another OS but nothing compares to a real OS installation.

In my experience, unless you have to (like for some embedded targets) cross-compiling is usually a pain in the neck you don't want. A native OS install (in a VM or otherwise) with a local native tool-chain is just so much easier to work with.

You can build a Windows executable from Linux if you install the whole cross-compilation toolchain (cross-compiler and cross-compiled libraries). The same is also available to compile Linux executables from Windows. I don't think it's as easy (or even possible) for OS X.

As I said, for Android, iOS and other mobile platforms, cross-compiling is the easiest solution. Compiling natively on a mobile platform requires some hacks (for example, to compile on an iPhone you must jailbreak it, then install gcc with Cydia and use SSH to run things directly on the phone).

Sounds like a real hassle. This is probably another topic but is using something like NDK considered to be cross compiling? Since you are compiling from MacOS/Windows for Android.

Laurent, how do I cross compile?
My target OS's are linux, windows and mac (Less important), not phones.
Do I have to compile it on the target OS to make an executable for it?

It's complicated, you'd better find a good tutorial ;)

Okay, thanks.
What's the best IDE working on the different OS's that requires the fewest changes for compiling?

There isnt really any "best" IDE, its really personal preference. Code between IDEs is virtually the same except for any platform specific code. Visual Studio is Windows only, Code::Blocks is Windows, Linux and Mac (I think), and there is also CLion as well.

The IDE doesn't matter. With a proper build system, like SCons, CMake, QMake or plain make, the IDE you use and the OS you build on is mostly irrelevant.

What matters is the code you write. If you write it using notepad, emacs, vi, visual studio or something else does not matter.

That's right, but how do I build a visual studio solution for example on linux OS?

Take the source and compile it on Linux.
