Supported Compilers

Boost is tested on a wide range of compilers and platforms. Since Boost libraries rely on modern C++ features not available in all compilers, not all Boost libraries will work with every compiler. The following compilers and platforms have been extensively tested with Boost, although many other compilers and platforms will work as well. For more information, see the regression test results.

New for this release: Support for building with the newest STLport-5.0 was added. The support includes building with MinGW Runtime 3.8 plus STLport-5.0 improved to support wide character operations. Apple GCC 4.0, HP Tru64 C++, and Microsoft Visual C++ 8.0 are supported platforms. We have added an experimental autoconf-like configure script for Unix-like systems: run configure --help for more information.

  • Apple GCC 3.3, 4.0 on Mac OS X.
  • Borland C++ 5.6.4 on Windows.
  • GNU C++ 2.95.3 (with and without STLport), 3.2.x., 3.3.x, 3.4.x, 4.0.x on Windows, Linux and Solaris.
  • HP C++ for Tru64 UNIX 7.1.
  • Intel C++ 8.1, 9.0 on Windows, Linux.
  • Metrowerks CodeWarrior 8.3, 9.4, 9.5 on Mac OS X and Windows.
  • Microsoft Visual C++ 6.0 (sp5, with and without STLport), 7.0, 7.1, 8.0. Note: Boost does not support the non-standard "Safe" C++ Library shipping with Visual C++ 8.0, which may result in many spurious warnings from Boost headers and other standards-conforming C++ code. To suppress these warnings, define the macro _SCL_SECURE_NO_DEPRECATE.

Important - New Toolset Names

The names of some the Boost.Build toolsets have been changed to remove the "." (dot) character and to fix some other naming inconsistencies. For example, vc7.1 toolset was renamed to become vc-7_1. Please refer to the Supported Toolsets section of the installation guide for the complete list of the current toolset names. This change was made as a part of the effort to make the Boost distribution compatible with ISO 9660 level 2 requirements.

1.31.0 (26 Jan 2004)

New License

A unified Boost Software License has been developed and will gradually replace the individual licenses for most Boost libraries. The new license offers better legal protection for both users and developers, and should speed user's legal reviews of Boost libraries. Dave Abrahams led the Boost effort to develop better licensing. The legal team was led by Diane Cabell, Director, Clinical Programs, Berkman Center for Internet & Society, Harvard Law School. Devin Smith, attorney, Nixon Peabody LLP, wrote the Boost License. Eva Chan, Harvard Law School, contributed analysis of issues and drafts of various legal documents.

Note: Many of the Boost libraries are still using earlier licenses, though all conform to the Boost License Requirements. After this release we will begin an effort to move toward uniform use of the new license.

Minor fixes to smart_ptr.hpp and cast documentation.

1.10.3 (30 Dec 1999)

Minor fixes to the compose library examples, operators documentation, operators.hpp, cast documentation, cast.hpp, config.hpp, and smart_ptr.hpp. This is the first release with a version number. The version numbering scheme is xxx.yyy.zzz.

xxx = Major version
yyy = New library or feature added
zzz = Bug fixes only

14 Dec 1999

Operators.hpp documentation improved.

13 Dec 1999

Added iterator operators and helpers to header operators.hpp, together with an iterator test program. This header is maturing into something really useful for building arithmetic or iterator user-defined types, so look it over even if you browsed one of the earlier versions.

11 Dec 1999

Added next() and prior() to header utility.hpp.

8 Dec 1999

Minor improvements to the smart pointer library: operator ==, operator !=, and specializations for std::swap and std::less now provided.

18 Nov 1999

Minor improvements made to the Operator templates.

15 Nov 1999

Operator templates have been added to the utility library.

11 Oct 1999

Minor smart pointer library and config.hpp changes to improve portability.

26 Sep 1999

Minor updates to several libraries:

  • polymorphic_downcast<> in the utility library cast.hpp header now works for multiple inheritance cases.
  • shared_ptr<> and shared_array<> swap() functions added in the smart pointer library.
  • timer.hpp elapsed_max() and elapsed_min() functions added to the timer library.
  • integer library bin_ubin.hpp changes to eliminate compiler warning messages.
  • config.hpp minor changes to aid library developers. No impact on library users.

3 Sep 1999

The cast functions in the utility library were considerably simplified.

1 Sep 1999

The cast functions initially in utility.hpp have been moved to cast.hpp, still in the utility library.

1 Sep 1999

The category "Experimental" has been added to the library page. The integer library is the first entry.

...And the remainder are lost to the mists of time (for now, anyway)....
