I would like to compile a c++ program in cygwin (on windows) and then run it on a Linux machine.. The reason I don't want to just compile it on Linux is missing libraries, and a huge mess (including restricted access) to install these.
I was hoping I could just compile it, then copy the programname.exe-file to my linux folder and then run ./programname. But that doesn't work. Is there any way to do this?
Short answer is: You can't.
Longer answer: You can, but then you have to set up a cross-compiler that generates native Linux binaries. Or use an environment such as WINE in Linux.
The reason you can't just copy an executable file from Windows, even when compiled with GCC, is that the file have a specific format that is not seen as executable on Linux.

I compiled and ran a C++ program using Eclipse on my MacBook Pro. I now need to convert the Unix executable to a windows executable. How do I go about this? Specifally, how do I get this code to run on a Windows machine from the command prompt?
The only way you can get the unix executable to run on a Windows system is using a virtual machine (Something like VMWare or VirtualBox). This isn't REALLY running it on Windows, of course, it's setting up a UNIX system on Windows and running it on that UNIX system.
The executables (and the needed runtime environment) are vastly different between the two systems, you can't just run executables from one on the other.
Your only other option is to setup Eclipse on your Windows system and compile the application there.
You cannot "convert" an executable, you need to recompile for your target system. If you are using a GCC toolchain that is set up for Eclipse and there is no Mac specific code, it should be as easy as moving the project over, setting it up in Eclipse, and recompiling it. If that is too much of a hassle, you can consider setting up a Makefile and using MingW or Cygwin, or even Visual Studio if you'd like. If there is Mac specific code, then you need to look up the appropriate Windows documentation, or use something cross-platform like GTK+ or Qt.
I currently have MinGW for Windows and would like to develop for Linux(I have read that I need Headers), where would I get Linux headers and set up to compile both Windows and Linux programs with MinGW code::blocks.
Note: I have researched but could not find anything from Windows to Linux only Linux to Windows.
I do not exactly see what you mean by "develop", but if you want to work in an environment that produces binaries for some Linux system, you can not really "develop" because you cannot really run / debug them on Windows (when using cross-compilation).
On the other hand, if you want to develop code that compiles on Linux, you are already there. Since you are developing using MinGW, you are pretty much guaranteed that your code will compile under Linux with corresponding version of GCC. To produce a binary for the Linux distribution of choice, you can use VM, speed should not matter since you are not probably going to do it often.
I have an application written in C++ using wxWidgets. How can I compile it for Linux and Unix os like Debian, FreeBSD, CentOS, in Windows?
Thanks!
Not entirely sure if I understood the question, but I think you are asking if you can compile an application for linux using a compiler in the windows environment.
My short answer: No, but.
The but: You may be able to use Cygwin in windows, however I think there is an easier way. If you are uncomfortable with setting up your computer to have multiple partitions and installing linux on at least one of these partitions, you can use VirtualBox, VMWare, or similar virtualization software to "install" linux on your windows machine. From there you can set up build environments and such. As for how, I would leave your windows build as is, but then in create a Makefile for Linux (or use CMake to replace both your windows-specific builder (the vsproj if using visual studio, etc) and linux-specific builder (make)) so that your source will compile both on windows and linux without having to modify the actual code or project.
i would recommend to use CMake as build system
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/
