First, you should definitely contact sales@gnat.com regarding possible support for this configuration. GNATWorks, the VxWorks version of GNAT (*) Professional supports a number of targets and it is most certainly practical to port it to the SPARC card that you mention. Whether it is practical for you to do the port on your own is of course another matter. As for file names and preprocessing, I think you will find that it is much easier than you think. Certainly there is no need to change file names, and we have a number of customers who have ported very large systems (millions of lines of code, including preprocessed code) from VADS to GNAT very rapidly, e.g. within a few weeks, with our help. Robert Dewar Ada Core Technologies (*) A version of GNATWorks has recently sucessfully completed validation testing with version 2.1 of the ACVC suite. This is the first 100% validation of a VxWorks Ada 95 combination, including all the annexes, and most notably, passing 100% of the real time annex tests. -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
