By default, code compiled in MinGW’s GCC will compile to a native Windows X86 target, including. MinGW does not have a Unix emulation layer like Cygwin. It does not attempt to emulate or provide comprehensive compatibility with Unix, but instead it provides the minimum necessary environment to use GCC (the GNU compiler) and a small number of other tools on Windows. MinGW is simply a Windows port of the GNU compiler tools, such as GCC, Make, Bash, and so on. It consists of two parts: A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing substantial Linux API functionality and a collection of tools which provide Linux look and feel. If you distribute it along with the Cygwin runtime library (cygwin1.dll), you have to compile with its open source license.Ĭygwin applications by principle are not considered a “Native Win32 application” because it relies on the Cygwin POSIX Emulation DLL or cygwin1.dll for Posix functions and does not use win32 functions directly.įrom Cygwin’s website: Cygwin is a Linux-like environment for Windows. You can compile codes in Cygwin, and it will run on Cygwin. Your application can use Unix feature such as pipes, Unix-style file and directory access, and so forth, and it can be compiled with Cygwin which will act as a compatibility layer around your application, so that many of those Unix-specific paradigms can continue to be used. CygwinĬygwin makes porting Unix-based applications to Windows much easier, by emulating many of the small details that Unix-based operating systems provide, and are documented by the POSIX standards. This blog shows some differences among three alteratives to compile open source codes in Windows.
