This is an excellent project I'm really excited to see it happen.  To avoid 
repeating what Gedare has said below I'll focus on just the waf branch.  This is 
a project I've been working on for 4 years to replace the RTEMS build system 
using the waf build system:

  https://code.google.com/p/waf/

You can read the release announcement that has all the details related to this 
work:

  https://lists.rtems.org/pipermail/devel/2015-February/009837.html

While writing this I abstracted the build to allow for any compiler to be used.  
Work to support Clang has been added in the build system but is not complete.  
I'm happy to finish up this work to speed up your project.  There are still 
source changes that will have to be made in order to get RTEMS building and 
running under Clang.

At the moment RTEMS lacks an x86_64 BSP that would help us standardise compiling 
across several compilers.  For now it should be no problem to choose one or two 
different architectures that both GCC and Clang support.

As for the Eclipse plugin this will work nearly out of the box with waf.  The 
main focus would be integrating the options for using waf with Eclipse which 
should be a more general contribution to the waf project versus anything RTEMS 
specific -- that is not a problem for this project however you will need Java 
experience to work with Eclipse and minor Python experience.  I am happy to help 
with anything waf-related.

Please feel free to give the waf branch a test and familiarise yourself with it.


Amar.
