RISC OS Open are pleased to announce the immediate availability of release 25 if the Desktop Development Environment (DDE25). The DDE is the definitive set of tools you need to author applications for RISC OS, and indeed to build the operating system itself.
A considerable effort has been made to bring the DDE, C/C++, and Toolbox manuals back up to date. The Toolbox manual was last edited in 1994, so has some 20 years of catch up!
The examples provided are now clearer, and make extensive use of the shared makefile scheme, which drastically simplifies building the most common of application and module arrangements.
The tools themselves come with comprehensive change logs with fine level detail of bug fixes, but some of the highlights include:
- CC – the code generator can now optimise specifically for the ARM11 core, as featured on the Raspberry Pi platform, and accepts the #warning preprocessor directive to emit a throwback message
- ObjAsm – support for optional ARMv7 extensions and ARMv8 opcodes, plus stricter checking and more accurate warning reporting
- Linker – can now produce ‘Utility’ binaries directly from C object files
- DDT – the debugger now works reliably on Cortex-A platforms such as the BeagleBoard
Many of the new features and bug fixes are in direct response to
developer feedback so please keep it up!
Developers who have purchased a copy of DDE24 or refreshed their copy in the last 6 months will automatically receive an upgrade free of charge to their registered email address. These will be sent out over the next 7 days.
ROOL will also be attending the London show on Saturday 25th October 2014 where you can buy your copy for the special show price of £48 (inc VAT). It is also possible to refresh your copy for £24 (inc VAT) and the update will be delivered digitally after the show finishes.
The full DDE25 costs £50 (inc VAT) and can be delivered either on a fun ROOL branded memory stick in the post, or via download.
If you can’t make the show and wish to refresh your copy, simply email your developer number as described on the store page to qualify for £25 (inc VAT) half price upgrade.
If you have a copy of DDE as found on the NutPi product, this can be upgraded for just £12.50 (inc VAT) by sending your NutPi serial number, found by running the !PiSerial application, to the store email address. The NutPi version is almost identical to the full version, except that the tools only run on a Raspberry Pi – however the code they generate is suitable for any RISC OS computer.
