I am pretty much new to embedded device programming world so pardon my ignorance if any.
I am cross compiling a C++ program on arm architecture with eclipse on ubuntu.
Then i have to burn the code and see the output with the device that has a linux kernel in it.
Then i came across a tutorial about cross compiling C++ program on arm architecture with eclipse on Windows. So my question is, Can i run this program (from windows) on my embedded device which has a linux kernel in it????
Thanks

If you are using a cross compiler, then the answer is yes. It should produce a linux libraries and executive file. You might need to adjust the files parameters (like set permissions and execute flag).
Yes.
eclipse is a great tool, especially when coupled with gcc. You can definitely use a ready-built compiler to extend eclipse as long as that compiler is available for Windows.
Here is a link to some documentation on how to change the toolchain in an eclipse project -

I have a C++ module on windows which I want to compile such that I get a dynamic library for linux *.so.
Does a cross-compiler exist that can help me out?
Several comments mentioned using Windows Subsystem for Linux. I would personally recommend this as it is far easier than trying to use a cross-compiler. It also comes with the added benefit that you can test your code in the same environment in which you compile it.
https://learn.microsoft.com/en-us/windows/wsl/about is a great resource for getting started with WSL.
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.
I make this program in C++ using Code::Blocks on Ubuntu. I need to turn it into a Windows executable binary (.exe file), but I don't know how to do this. Is it possible?
If you meant, compiling an executable for Windows on Linux you might find some pointers on how to do that here.
Both the MinGW32 distribution of GCC and Wine should be available for your distribution.
MinGW has instructions and winegcc wraps a similar compiler that comes with the Wine distribution.
I've used both to compile both applications and libraries for Windows.
You could read here on how to compile wxWidget applications on Linux for Windows using Code::Blocks.
This is a fairly unusual question. What you're asking is that you want to develop on Ubuntu, but the target platform is Windows?
My guess is that you have an assignment to turn in. My belief is that you should go to a lab and compile it and make sure it's working.
However, doing some research, you should try mingw at http://www.mingw.org/
I have the source code for some very simple command line programs. I was considering the option of compiling them on a Linux machine (they were deveoped here) so they can be used on Windows. If I am not wrong this is called Cross-compiling. I have never tried it, but reading yesterday some information, it seems to be kind of complicated or not successful. I would like to hear about your opinions, and how could I port a simple "hello world" program, which compiles on Linux with g++.
Thanks
Look into mingw, a suite of tools for building Win32 applications in Linux. If the programs don't depend on any Linux-specific functionality not supported by mingw, you should be fine.
Note that cross-compilation is not the same thing as cross-platform. With cross compilation, you compile the code to a Windows executable on the Linux box, then transfer the executable to a Windows box. With cross-platform, you transfer the source code to the Windows box and compile to a Windows executable using a Windows compiler.
The former is quite difficult (but not impossible), the latter is very easy, using a compiler such as MinGW, a others have mentioned.
I cross-compile on a daily basis. But I don't set up cross-compilers on a daily basis. It can be tricky, but it's certainly possible.
As long as you use standard C++ your code will be cross-platform. You can also use cross-platform libraries like STL, boost, Poco, Qt, etc...
Only when you start to use platform specific code you lose portability. For example including <windows.h> will make your code only compilable on Windows. (There are techniques around this like the #ifdef macro. This enables certain code portions only on one platform.)
So a simple hello world program should work on Linux, Mac, Windows or any other platform. You don't need anything special for this.
Note:
Some may mention Cygwin or mingw32. I'll briefly explain what they are:
Cygwin allows you to compile Linux applications using gcc/g++ on a Windows machine.
Mingw32 allows you to compile Windows applications using gcc/g++ on a Windows machine.
Edit:
If you want to setup a system for cross-compilation, then I recommend that you have a look at cmake.
Yes. We are currently compiling a 250 kloc app, running Qt with daily builds. It's working prefectly everyday, although I've to admit it is not distributed outside the company, but only used internal. For official releases, Visual Studio is prefered.
Compiled using mingw standard packages on Debian.
How can a cross compilation setup be achieved to allow compiling Cell Linux programs on a Windows PC using the cygwin toolchain? The cygwin tools provide a GNU compiler to use in building the cross compiler, and associated tools for the build process e.g. rpm, cpio, make, flex, bison and so on.
I am moderately confident this is possible, but unaware of anyone who has actually done this. It has already been done for x86 Linux, but I wish to use Windows, without requiring the use and overhead of a virtual machine running an entire 2nd operating system.
The Cell Linux toolchain is a patched GNU toolchain, with C and C++ compilers for the PPU and SPU processors, and associated binutils. The sources for the Cell Linux SDK for Cell Linux can be found here. The source RPMS here have build scripts for use with the rpmbuild tool on Linux.
The specific question is: how can a set of Cell Linux GNU compilers for the PPU and SPU processors be built, on Windows, using Cygwin.
I've never done it, so I can't give you step by step instructions, but I can give you a general idea.
The instructions you linked will serve as a pretty good outline, but there will be definite changes.
For the host PC, you can install gcc and other build tools from MinGW or cygwin. That will give you the windows native parts of your toolchain.
Then you'll need to download the sources for the cell portions of the toolchain and compile them (with the appropriate options, --target, etc.) using the build environment you just installed.
Then you download and compile the sources for libspe2, and you're done.
But I'll warn you - it sounds easier than it is. Be prepared to spend a lot of time on it.
Since you can already do this on Linux x86, why don't you just install Linux a virtual machine? Also, what might be even easier, is to install Portable Ubuntu for Windows. It runs Linux alongside Windows using coLinux. Although this may not be optimal, it is probably much easier than trying to compile everything on Windows.
the ps2dev toolchain can easily be set up under cygwin
http://ps2dev.org/ps3/Tools/Toolchain
You should be able to build a canadian cross compiler on Linux that runs on windows and creates code for PS3. Have a look at the excellent crosstools from Dan Kegel.
Did you check if the Cell/PS3 devtools for windows/cygwin work for you?
A set of tools compiled to run on Windows via Cygwin can now be found on Sourceforge.
Mike Acton has a long, detailed article on cross-compiling for PS3 Linux on his Cell Performance blog.
It may be a bit out of date, but the bits on setting up the toolchain and various SDKs might prove handy.
