I double checked our head file inclusion --- they are exactly as warpmac.c / ackmac.c. Is it possible that we are missing critical steps in software platform setting?
Thanks.

Does your hardware platform include a UART core? If you used one of our reference designs or Base System Builder, it will be an instance of the opb_uartlite core named RS232, visible in System Assembly View. If you're sure you have that, double check that the UART is selected as the STDIN/STDOUT in the Software Platform Settings.
If that doesn't help, please post the content of your MSS file. This is the text file that specifies all of the software platform settings. You can open it under the Project tab in XPS.

Thanks. Compilation passed.
I missed the step to set STDIN/STDOUT in Software Platform Settings
It would be great if WARP team can draft a simple tutorial on software platform settings and post it on the website. I think this will be very helpful for beginning users.

Hey zrcao, I keep a user guide I've written on XPS/EDK/Xilkernel for WARP here:
http://warp.rice.edu/trac/wiki/ppc_prog_overview
There's a bit on software platform settings here:
http://warp.rice.edu/trac/wiki/ppc_prog … Essentials
It seems to not be linked on the main page anymore. I'll see what's up with that.

OK. The link to the XPS-user guides is up again on the main page
The link itself for the software guide is here:
http://warp.rice.edu/trac/wiki/SoftwareUsersGuides
There's still a lot of useful software-tidbits floating around the rest of the site though -- particularly in the FAQs...
