- The Microsoft Visual C++ 2010 Express Edition. It also allows you to build applications that target the Common Language Runtime (CLR). You should read their license for yourself to make sure. MFC, ATL and the Windows headers/libraries are not included with this version. To create Windows programs, you will need to download the Microsoft Platform SDK as well (for the Windows headers and import libraries).
- HP-GCC comprises the GNU C compiler targeted at the ARM processor of ARM-based HP calculators (like the HP49g+), HP specific libraries, a tool (ELF2HP) that converts the gcc produced binary to the appropriate format for the HP calculator, and an emulator (ARM Toolbox/ARM Launcher) that lets you execute ARM programs on your computer. At present, only a Windows version is available, but the site says that Linux and Mac OS X versions are "on the way".
- Ultimate++ a C++ cross-platform and Open Source rapid application development suite focused on programmers productivity. It includes a set of libraries (GUI, SQL, etc..), and an integrated development environment.

- Intel Compiler, a Intel® compilers. Compatible with the tools developers use, Intel compilers plug into popular development environments and feature source and binary compatibility with widely-used compilers. Every compiler purchase includes one year of Intel® Premier Support, providing updates, technical support and expertise for the Intel® architecture. [Intel CPUs ONLY]
- Comeau C/C++ Compiler. It is closest to the C++ Standard. Available for purchase Comeau C/C++ supports Core C++03 language enhancements for all major and minor features of C++ and C, including export.
Misc. C++ Tools 
Free or with a free version 
- Doxygen is a documentation system for C++, C, and other programming languages.
- Valgrind, a system for debugging and profiling applications at runtime. The system runs on nearly any x86 linux (sorry, no amd64 yet). It can detect memory leaks, illegal memory access, double deletes, cache misses, code coverage and much, much more.
- Microsoft Visual C++ Toolkit 2003, This is a free optimizing compiler provided by Microsoft that developers can use to develop and compile applications in C or C++. It is the same compiler that ships with the professional edition of Visual Studio. It ships with the standard library and sample code.
- ccbuild, a C++ source scanning build utility for code distributed over directories. Like a dynamic Makefile, ccbuild finds all programs in the current directory (containing "int main") and builds them. For this, it reads the C++ sources and looks at all local and global includes. All C++ files surrounding local includes are considered objects for the main program. The global includes lead to extra compiler arguments using a configuration file. Next to running g++ it can create simple Makefiles, A-A-P files, and graph dependencies using DOT (Graphviz) graphs. (Linux only)
Free or with free usable versions 
- The Boost web site. Boost is a large collection of high-quality libraries for C++, some of which are likely to be included in future C++ standards.
- The WFC (Win32 Foundation Classes) site.
- The WTL site.
- Blitz++ is a C++ class library for scientific computing which provides performance on par with Fortran 77/90. It uses template techniques to achieve high performance. The current versions provide dense arrays and vectors, random number generators, and small vectors and matrices. Blitz++ is distributed freely under an open source license, and contributions to the library are welcomed.
- STLFilt is a STL Error Message Decryptor for C++. It simplifies and/or reformats long-winded C++ error and warning messages, with a focus on STL-related diagnostics.
- GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers. There is no practical limit to the precision except the ones implied by the available memory in the machine GMP runs on.
- Crypto++ Library is a free C++ class library of cryptographic schemes.
- Allegro is a game programming library for C/C++ developers distributed freely, supporting the following platforms: DOS, Unix (Linux, FreeBSD, Irix, Solaris, Darwin), Windows, QNX, BeOS and MacOS X. It provides many functions for graphics, sounds, player input (keyboard, mouse and joystick) and timers. It also provides fixed and floating point mathematical functions, 3d functions, file management functions, compressed datafile and a GUI.
- FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X. FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL® and its built-in GLUT emulation. FLTK is designed to be small and modular enough to be statically linked, but works fine as a shared library. FLTK also includes an excellent UI builder called FLUID that can be used to create applications in minutes.
- Simple DirectMedia Layer is a cross-platform multimedia library for C/C++. It provides low-level acces to 2D frame-buffer and hardware accelerated 3D graphics(using OpenGL), audio, threads, timers,user input and event handling. Other features are available through "plug-in libraries". Linux, Windows, BeOS, MacOS Classic, MacOS X, FreeBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX are supported and there's some unofficial support for other platforms. SDL is available under the GNU LGPL license.
- SDKs for older platforms and from third parties. Includes a redistributable that contains the MFC library's for Windows CE 1, 2, HPC Pro, Palm-Size PC 1.2, HPC2000 and a limited number from Windows CE 4.0.
- Qt (pronounced "cute"), a multi-platform API that contains a UI toolkit as well as a core library. It is extremely modular, but to use it effectively, you should use at least UI+Core.
- Loki is a C++ library which demonstrates and encourages the use of generic programming and design patterns. It was written to accompany the book entitled "Modern C++ Design." The library includes a parametrized smart pointer class, generalized functors, a multi-threading abstraction, and some help for important patterns. Open source released under the MIT license.
- TinyThread++, a light weight, portable C++ thread library that implements a subset of the C++0x standard, including the thread, mutex and condition_variable classes. Open source, released under the zlib/libpng License.
- Poco C++ Libraries. Written in modern, standard ANSI C++, using the C++ Standard Library. Modular design, very few external dependencies, builds out-of-the-box. Good mix of "classic" object-oriented design with modern C++. Clean, easy-to-understand code, consistent coding style, comprehensive test suite.
