wine commit id fb6b1c91bbf412f5eba260ae52ee38176fd693d4 by Paul Gofman <pgofman@codeweavers.com>

NOTE: This implementation is disabled for ReactOS, and we keep
our own. See the comment block in the code for the reasons why.

+ Adaptations for ReactOS-specific code.

In particular, great care has been taken to keep the `pkill_list`
functionality (read: fix) introduced in PR #2403 (commit 97e7efc020).
The current problem with Wine's code is that if many processes (more
than one) with the same image name are running, then:

   taskkill /im theimagename.exe

would only terminate *one* of the corresponding processes, instead of
all processes having this same image name (as on Windows).
The `pkill_list` array contains all the PIDs of these processes. This
replaces the single `pid` initialized by `get_task_pid`.

What is ReactOS?

ReactOS™ is an Open Source effort to develop a quality operating system that is compatible with applications and drivers written for the Microsoft® Windows™ NT family of operating systems (NT4, 2000, XP, 2003, Vista, 7).

The ReactOS project, although currently focused on Windows Server 2003 compatibility, is always keeping an eye toward compatibility with Windows Vista and future Windows NT releases.

The code of ReactOS is licensed under GNU GPL 2.0.

Product quality warning

ReactOS is currently an Alpha quality operating system. This means that ReactOS is under heavy development and you have to be ready to encounter some problems. Different things may not work well and it can corrupt the data present on your hard disk. It is HIGHLY recommended to test ReactOS on a virtual machine or on a computer with no sensitive or critical data!

Building

Build rosbewin.badge rosbeunix.badge coverity.badge

To build the system it is strongly advised to use the ReactOS Build Environment (RosBE). Up-to-date versions for Windows and for Unix/GNU-Linux are available from our download page at: "Build Environment".

Alternatively one can use Microsoft Visual C++ (MSVC) version 2019+. Building with MSVC is covered here: "Visual Studio or Microsoft Visual C++".

See "Building ReactOS" article for more details.

Binaries

To build ReactOS you must run the configure script in the directory you want to have your build files. Choose configure.cmd or configure.sh depending on your system. Then run ninja <modulename> to build a module you want or just ninja to build all modules.

Bootable images

To build a bootable CD image run ninja bootcd from the build directory. This will create a CD image with a filename bootcd.iso.

You can always download fresh binary builds of bootable images from the "Daily builds" page.

Installing

By default, ReactOS currently can only be installed on a machine that has a FAT16 or FAT32 partition as the active (bootable) partition. The partition on which ReactOS is to be installed (which may or may not be the bootable partition) must also be formatted as FAT16 or FAT32. ReactOS Setup can format the partitions if needed.

Starting with 0.4.10, ReactOS can be installed using the BtrFS file system. But consider this as an experimental feature and thus regressions not triggered on FAT setup may be observed.

To install ReactOS from the bootable CD distribution, extract the archive contents. Then burn the CD image, boot from it, and follow the instructions.

See "Installing ReactOS" Wiki page or INSTALL for more details.

Testing

If you discover a bug in ReactOS search on JIRA first - it might be reported already. If not report the bug providing logs and as much information as possible.

See "File Bugs" for a guide.

NOTE: The bug tracker is not for discussions. Please use our official chat or our forum.

More information

ReactOS is a Free and Open Source operating system based on the Windows architecture, providing support for existing applications and drivers, and an alternative to the current dominant consumer operating system.

It is not another wrapper built on Linux, like WINE. It does not attempt or plan to compete with WINE; in fact, the user-mode part of ReactOS is almost entirely WINE-based and our two teams have cooperated closely in the past.

ReactOS is also not "yet another OS". It does not attempt to be a third player like any other alternative OS out there. People are not meant to uninstall Linux and use ReactOS instead; ReactOS is a replacement for Windows users who want a Windows replacement that behaves just like Windows.

More information is available at: reactos.org.

Also see the media/doc subdirectory for some sparse notes.

Who is responsible

Active devs are listed as members of GitHub organization. See also the CREDITS file for others.

Code mirrors

The main development is done on GitHub. We have an alternative mirror in case GitHub is down.

There is also an obsolete SVN archive repository that is kept for historical purposes.
