I recently revised our notes on how to port open-source code to VOS and OpenVOS. This new revision is about 30% longer and contains much more detailed information. Working with my colleague Richard Boylan, we have attempted to pull together into one central location the collected wisdom of each Stratus software engineer that has ported open-source code. Even if you have ported code before, I think you will find the document helpful. If you have never ported code to VOS, reading these notes can save you a lot of time and energy.
Please see http://ftp.stratus.com/pub/vos/posix/Porting_Open-Source_Code.pdf.
If you have questions or comments about this area, please post them in the OpenVOS forum.
