Is there a way of using libraries built in Linux on Windows, without porting and rebuilding them?
The short answer is "No". Although there is a way of doing that vice-versa (via WINE).
That would require loading ELF binaries. Extending the loader in Windows seems to be difficult if not impossible, going by the answers to this question:
Is it possible to replace Loader of an OS? Any way to obtain the control over Loader?

I'm starting to work on my master thesis at the moment and I have a (maybe) specific question...
I want to stay on windows OS and run a Linux VM via VirtualBox combined with Vagrant. No Problem. I like the feature to reset the VM via vagrant easily.
The next target is using features like auto-completing or similar while developing in C++. This would help me to work with unknown includes/libraries.
Is it possible to access the filesystem/compiler of the VM while using an IDE (like clion) installed on windows? Without explicit loading of the gui und running the IDE on it? Kinda like working with cygwin? I don't want to use cygwin because it doesn't support c++11 standard (or is there a way???)
Maybe you know an alternative way. I would be glad for all hints solving my problem.
I don't know much about cygwin, though I would be surprised if they cannot get recent versions of gcc. But for certain, you can use MSYS2 to get very recent versions of gcc and many other linux packages, which will support C++11.
It's a matter of opinion how best to do cross-platform development, but an alternative worth mentioning is to use cmake for your project. When you want to code in windows, it can make MSVC 2015 project files for you -- when you want to compile in linux, it can find the dependencies and generate a makefile for you to use. IIUC, cmake is the most widely used cross-platform build system right now, besides gnu make itself. (I'm pretty sure it's more popular than "autotools" nowadays, and its definitely more popular than scons.) The advantage is that you avoid the need to maintain multiple platform-specific project files that essentially say the same thing with different formatting.
I was wondering if it's possible somehow to use windows.pas on OS X with Lazarus?
I need to use special library in my project, and one of key-files uses windows.pas :( Any ideas?
Windows.pas only works on Windows. You will have to edit the library to put an IFDEF around it in the uses clause, and then provide alternatives for any functionality that is then broken. Or contact the library author and see if there is already a non-Windows version available.
You certainly cannot use Windows.pas under OSX. Because Windows.pas exposes the functionality of the Win32 library.
If you need to execute Win32 code on OSX pretty much your only option is Wine.
A more plausible solution is that you find an alternative to this "special" library to which you refer.
Windows.pas is mostly a wrapper around different DLLs contained in the Windows operating system. As it is unlikely that you will find those DLLs in OSX I guess you are out of luck.
You could check the library's source code and try to identify the constants, procedures and functions that are used in windows.pas. If it is not too much code you could try to modify the library so that it uses corresponding Carbon functions instead.
While the various answers are correct, and the vast bulk of unit windows is not portable, some functionality IS abstracted. Structures like interlockedincrement, Rect and ColorRef, and some message related functionality. Have a look at types and lcltype and the system unit interface of FPC.
A lot of Delphi code still uses Windows for that functionality, while e.g. unit types already exists since D6.
Some other things are abstracted, but not using the same (windows unit) calls. Better explain what exactly you need in a separate post.
Is there an open source program for Windows that offers the same functionality as Linux' /lib/ld‑linux.so.2?
You might want to look at the ReactOS project.
They should have everything to load DLLs, and it is open-source.
The loader is a core part of the OS on Windows; there's no open-source alternative I'm aware of, and I'm not sure it'd be possible to do it correctly in any case - you have to handle the minefield of assumptions that kernel32/ntdll have regarding address space layout, support SxS, ASLR, hotpatching, and more.
Open-source linkers are common (e.g., gnu tools), but I gather that's not what you're after.
The Enhanced Dynamic Linking Library for MinGW under MS-Windows may be helpful. Take a look especially at the bottom for the edll solution.
You mean using dynamic libraries? In Windows that's automatic when you use LoadLibrary on a .DLL.
I want to make an easy to deploy Windows application and was was wondering which programming systems can create totally self contained Windows .exe files?
As a plus, if the same can be done with MacOSX and Linux from the same source this would be a bonus. I took a look at Realbasic but they have since abandoned the single .exe concept.
update: i am looking for something that can run from Windows XP up to Windows 7, no matter what version of .NET is installed. Is this even possible?
Delphi compiles to one executable, and generates native windows executables. So no dependencies to any kind of framework. If you use Free Pascal (fpc) and the Lazarus IDE, you could even develop for Linux and Apple from the same source.
If your using external dll's this would become a bit more tricky, but you could pack them up in your resource file and still maintain the one exe property.
Update 2020: since #Vassilis & #Marco van der Voort commented on this, I would like to update my old andswer and add that go is a very good way to make self-contained executables. Even crossplatform compilation is realy simple.
You can certainly do this with C/C++. Technically the runtime libraries are required, but they should already be installed on any windows, mac or linux system.
With .NET you can compile to an EXE, but of course the .NET framework is required. For newer versions of windows it should be installed by default, but on older versions (XP or older?) it may or may not be there. And of course you couldn't expect mono to be there by default on linux or mac either.
For Windows the following languages are viable:
C (MS, gcc)
C++ (MS, g++, Digital Mars)
D (Digital Mars)
Delphi (Embarcadero??? how do you spell that? just trips off the tongue doesn't it?)
Fortran (Intel, Salford Software)
Visual Basic 6 (MS)
Lua (you'll need a special tool to do it, but it is doable)
C#, VB.Net, F#, J#, etc (assuming that you don't mind using .Net technology)
You can use Tcl/tk. The technology you should research is a "starpack", which combines a runtime executable (a starkit) with a platform-specific runtime (a "tclkit") to create a single-file executable. It's remarkable in the fact that it's not just compiled code, but an entire self-contained virtual filesystem that can include images, sound, data, etc.
This same technology works for many platforms from the same code base. The only thing that is different is the platform-specific runtime. You can even "cross compile" in that you can copy the runtime for multiple platforms onto your dev box and then build starpacks for each platform without having to actually be on each platform.
Tcl can do this, especially through producing starpacks. They can be produced for all platforms from the same code. Note that this also includes all the necessary runtime libraries (except for things like the C library, but you don't want to make that static under normal circumstances).
JavaFX 2.2 supports that. It allows creation of self-contained applications targeting Windows, Mac OS, and Linux.
Please follow this link for more information: http://docs.oracle.com/javafx/2/deployment/self-contained-packaging.htm.
I would recommend taking a look at AutoIt. It is an easy-to-use scripting language that will compile into an exe, so there are no runtimes needed. This would be for windows only though.
http://www.autoitscript.com/autoit3/index.shtml
From the website:
AutoIt v3 is a freeware BASIC-like
scripting language designed for
automating the Windows GUI and general
scripting. ... AutoIt is also very small,
self-contained and will run on all
versions of Windows out-of-the-box
with no annoying "runtimes" required!
c/c++
purebasic
delphi
vb6
i hope this help :)
Here's a good source for a number of basic-like programming languages that build small stand-alone EXEs. Some are cross-platform for Windows and Linux:
www.basic.mindteq.com
You can use Liberty Basic which is easy and cheap, you can easily make stand alone programs for windows but not possible to transfer to MacOS or Linux.
You can do this for Windows with .NET languages using ILMerge
ILMerge is a utility for merging multiple .NET assemblies into a single .NET assembly. It works on executables and DLLs alike and comes with several options for controlling the processing and format of the output. See the accompanying documentation for details.
However:
Currently, ILMerge works only on Windows-based platforms. It does not yet support Rotor or Mono.
QBasic can :-)
I wrote a few command line tools using it!
I want to know how I can develop GUI applications(32 Bits) without using Delphi language(Object Pascsl), only by using FPC with Lazarus installed(Pascal). Thanks.
Use a widget set directly. Look at e.g. the examples in packages/gtk2 for unix, or the windows win32api usage demo. (demo\win32 in the FPC win32 installation)
But not using lazarus makes you lose platform independance, and a lot of ease.
Looking how lazarus does it, is still a possibility.
A second option is https://github.com/mse-org/mseide-msegui
You can also use FPC Qt4 Binding.
Take a look at built in LCL, and external fpGUI and mseGUI.
