GCC Logo The GCC developers have announced the availability of version 4.5 of the GNU Compiler Collection. The major release includes several changes and new features over the previous 4.4.x branch in addition to a number of bug fixes.

GCC 4.5 features improved experimental support for the upcoming ISO C++ standard, C++0x, including support for raw strings, lambda expressions and explicit type conversion operators. An experimental profile mode has also been added to the libstdc++ runtime library. Other improvements have been made to the optimiser and integration with the MPC library allows GCC to more accurately evaluate complex arithmetic during optimisation. The developers also note that GCC now requires the MPC library in order to build.

New target platforms include among others the ARM Cortex-M0 and Cortex-A5 processors and the ARM v7E-M architecture and MIPS 1004K processors. Support for a number of older platforms, such as older versions of Tru64 Unix, Irix and Solaris 7, has been discontinued.

More details about the release can be found in the change log. GCC 4.5 is available to download from one of the GCC mirror sites. Version requirements can be found on the prerequisites page. The GNU Compiler Collection is released under version 3 of the GNU General Public License (GPLv3).
