Hi list,

I am pretty sure I know what is the problem. After reading the installation manual (http://www.xilinx.com/cgi-bin/SW_Docs_Redirect/sw_docs_redirect?ver=12.4&locale=en&topic=release+notes), I found out that I did not appropriately set the environment variables. It should be done with the command 'source settings32.(c)sh' when in your XILINX installation directory (explained on the page 25 of the manual).

However, in addition to this, the license has to be set up. Since I have to point to a license found on a server, this corresponds to the chapter 'Client Machines Pointing to a Floating License' in the manual (page 50). However, this is what is written in the manual for setting the floating licenses in linux:

"Note: For Linux operating systems, licensing environment variables cannot be set using the Xilinx
License Configuration Manager (XLCM). The environment variable fields are read only, and they are
grayed out and there are no “Set” buttons. The environment variable must be set using the
appropriate shell and commands."

Can anyone help me with this?

Thank you in advance for your reply!


P.S. As a student, I am not allowed to create a WebCase in order to get help from a Xilinx engineer, so I do not have whom other to ask.

The current error output:

This is wandering very far away from the core topic of Gnu Radio, and into "help with Xilinx Tools".  You *may* find people on this list who
  can help you, just by pure blind luck, or maybe not.

From the looks of it, and I'm no TCL expert, it looks like it was unable to create the "build" directory--I'd check the permissions on the directories
  leading up to ...top/USRP2/build .  Did you perhaps unpack them as "root", and now you're trying to "do stuff" as your ordinary user, so the
  directories are owned by root, so they're not writable to you?
