4.10 Release Notes

Open Ideas are are: RTEMS410Ideas?

This page lists the changes and improvements that are planned and/or have been made to the RTEMS development source since the 4.9 release branch was made. As usual, there will be submissions that are not expected and incorporated as ready into the 4.10 releases. In keeping with project history, the feature set of the 4.10 release series will be largely be driven by user submissions and requests.

<blockquote> Any snapshots made during this development effort are numbered 4.9.99.x. </blockquote>

<blockquote> The RTEMS project provides built tools sets that are available for download. For Linux the RPM package formater is support and avaliable from the APT/Yum Repository. For Windows MinGW Executable Installers are available. </blockquote>

If any changes or enhancements are missing in this list, feel free to add them. After all, that's why this is a Wiki.

Tool Improvements

  • TBD
  • Thanks again to Ralf, it is possible to provide target specific versions of the development tools. This is important when GCC drops support for an old architecture or we are avoiding target specific bugs in a particular tool version. Nominally, most RTEMS targets will use the same tools and they have been upgraded to the following versions:
    • autoconf 2.63
    • automake 1.10.1
    • binutils 2.19 (expected)
    • gcc 4.4.x (expected) for C/C++ with newlib 1.16.0
    • gdb 6.8

The latest patch for each tools is in rtems/contrib/crossrpms/patches.
