The MinC project (MinC Is Not Cygwin) develops a minimalist kernel (takes up 285Kb) and a toolkit based on MinGW, allowing for the re-compilation and execution of standard OpenBSD utilities in Windows, similar to how the Cygwin package enables the use of GNU utilities in Windows. The project's code is written in C and distributed under the BSD license. It supports operation in versions of Windows from Windows XP to Windows 11.
After installing MinC, the user obtains an environment simulating OpenBSD operation in Windows, providing performance close to native execution. This is accomplished with the help of the libtrace and libposix libraries, which translate the necessary functions and system calls for OpenBSD applications into a format compatible with Windows. Standard libraries libc, libdl, libsocket, and libutil from OpenBSD are provided for program compilation.
The environment corresponds to the OpenBSD 6.1 release and includes the following sets of programs:
- Standard utilities such as ls, du, ps, df, find, grep, awk, mkdir, chmod, chown, wc, top, and diff.
- Text editors vi and nano, as well as programs like less and hexedit.
- Archivers unzip, gzip, bzip2, and xz.
- Network utilities route, ifconfig, ping, ftp, ssh, scp, telnet, wget, curl, lynx, mutt, and BitchX.
- Development tools: vim, git, ImageMagick.
- While not included in the package yet, server applications such as Apache httpd, Sendmail, and sshd will be added soon.
Among the advanced features is support for integration with the Visual Studio Code editor to use MinC as a terminal. A graphical installer has been prepared to allow the selection of additional application sets apart from the basic system environment. MinC works correctly with antivirus packages such as Windows Defender and Kaspersky Anti-Virus.
