Official Tools CD available for online purchase

Posted by Steve Revill Thu, 30 Apr 2009 20:25:00 GMT

Some time ago, RISC OS Open took over the official set of C/C++ Development Tools for RISC OS. We are pleased to announce that these can now be purchased for £50 (plus £1 p&p, plus VAT) from our sale page here.

There are already some minor updates and fixes to our latest build of the Tools, including:

  • fix to divide by zero error in modsqz
  • fix to buffer overrun in the link tool
  • minor changes to the C compiler, cc
  • the decaof tool now supports a significant number of ARM v6 an v7 instructions

We hope to continue to add to and improve the Tools for as long as they are the only sensible way to build the published RISC OS sources.
