Crosstool-NG 1.5.0 released, with new features!

Crosstool-NG, the successor of Crosstool, is a tool that automates the complicated process of building a cross-compilation toolchain. It provides a nice menuconfig interface to fine tune the configuration of the toolchain, before creating the toolchain automatically by retrieving, extracting, patching, configuring, compiling and installing the different components in the right order, with the right arguments and configuration.

Yann E. Morin, the maintainer of Crosstool-NG has just announced the release of Crosstool-NG 1.5.0, with the following new features:

  • Support for gcc 4.4
  • Experimental support for canadian-cross toolchains. Canadian-cross toolchains are toolchains that are built on machine A, to run on machine B and generate code for machine C, while usual cross-compilation toolchain are built on machine A, to run on machine A and generate code for machine B
  • Experimental support for AVR32, with support for operation as MMU-less, thanks to the newlib C library

In addition to these important features, bugs have been fixed and improvements have been made. Yann also switched the development of Crosstool-NG from Subversion to Mercurial, in order to ease community participation in the improvement of Crosstool-NG.

By the way, if you are interested in Crosstool-NG, don’t miss Yann E. Morin’s talk at the Embedded Linux Conference Europe 2009. See the program for details.
