The GCC compilers in /mingw32/bin and /mingw64/bin produce native Windows executables targeting the 32-bit or 64-bit versions of Windows respectively. That environment is mainly for running programs from the Linux world (like bash) which need POSIX commands and cannot be easily ported to a native Windows environment. That DLL is basically a fork of Cygwin, and it provides emulation of POSIX commands not normally available on Windows. The GCC compiler in /usr/bin produces executables that use msys-2.0.dll as a runtime dependency. What's the difference between /usr/bin and /mingw64/bin MSYS2 (in this guide) is actively maintained and provides an up-to-date GCC toolchain as well as many others, is the prefered choice. Please DO NOT follow this guide on Vscode's official tutorial, because the Mingw-w64 project provides an out-dated GCC toolchain. MSYS2 is a collection of tools and libraries providing you with an easy-to-use environment for building, installing and running native Windows software.īut basically, we use its implementation of MingW(Minimalist GNU for Windows), which is a collection of common developing tools seen on GNU/Linux operating systems. Don't be confused by the directory C:\msys64\clang64. Note: Clang and GCC is installed to the same directory, eg. The header files of libc++ will be stored at C:\msys64\mingw64\include\c++\v1. When invoking clang++, add the flag -stdlib=libc++. Optional): If you want to get clang's implementation of the C++ standard library (ie.
Open any shell such as cmd and type in clang -version and you shall see the following: Now search for environment variable and open itĬlick Environment Variables, find Path in System variables, double click to open the setting.Ĭlick New and copy C:\msys64\mingw64\bin to the new entry.Ĭlick OK to close all windows.

If you also want to install clang, skip this part and go directly to Install Clang, because GCC is a dependency of Clang (on MSYS2) and will be automatically installed when you install clang. Just launch the installer and keep clicking "Next" Install GCC This guide will cover the installation of GCC, Clang and MSVC.

I will admit, that most C++ programming books do NOT actually tell you how to set things up.Īnd I think that's hilarious, because how are you supposed to program without a working development environment?Īlthough some books do mention it, they usually target Unix operating systems. I know a lot of you are having troubles of getting it to work on Windows and complaining a shiton. The definitive guide of setting up C/C++ development environment on Windows
