A free, open-source, portable and extensible C/C++ IDE. Old Bloodshed versions are buggy and ship with a very outdated GCC compiler. Do yourself a favor: don't use the old versions. See "info" for alternatives.

Between 2011 and 2015, Orwell, a developer independent from Bloodshed (the original developers of Dev-C++), released improved and updated versions of Dev-C++. Therefore, it is not recommended to stick with the old Bloodshed Dev-C++ versions. Consider upgrading to for example:

  • Orwell Dev-C++ is free, open-source, ships with a 64bit compiler including less outdated resources like the Windows 7 API, and can be made fully portable with zero effort. However, it's not actively maintained and has no support for the last 3 C++ standards (14/17/20)

  • Embarcadero Dev-C++ is a modern fork of Bloodshed Dev-C++ and Orwell Dev-C++.

  • Microsoft offers a freeware version of their excellent Visual Studio IDE.

  • NetBeans, free, open-source, cross-platform IDE (see "C and C++ Development")

  • Qt Creator is a free, open-source, cross-platform IDE for building C++ applications.

  • Code::Blocks is often hailed as the obvious replacement for Dev-C++. It is free, open-source, cross-platform, and can be extended with plugins.

  • Eclipse is also a free, open-source, cross-platform IDE with pretty robust C++ support.

And of course, countless others are available.

So do yourself and everyone else a favor: Don't use the unmaintained Dev-C++, and certainly not the ancient Bloodshed Dev-C++.
