Finally got GNU Radio compiled and working with the USRP so I am out of the wood for now.
I installed it in the 'standard' location, unfortunately I could do that only as the root and I can only run GnuRadio as root. I can't even use 'sudo' to run usrp_oscope.py. Not sure if I should move this to another subject, let me know Eric. Here is what I did and the difficulties that I still having. I made a group and changed the /usr/local directories per Eric's recommendations. Eric wrote: > > Depends on your setup.

File access for a process is determined by its effective uid and effective gid. After making the changes to /usr/local based on my new group, I tried to build the base line software needed and got the following type of error while making sdcc: make -C `dirname hc08/port.a` make[2]: Entering directory `/opt/GnuRadio/sdcc/src/hc08' make[2]: Nothing to be done for `all'. make[2]: Leaving directory `/opt/GnuRadio/sdcc/src/hc08' /usr/bin/install -c -d /usr/local/bin /usr/bin/install: cannot change permissions of `/usr/local/bin': Operation not permitted make[1]: *** [installdirs] Error 1 make[1]: Leaving directory `/opt/GnuRadio/sdcc/src' I appears' that the make is trying to change permission on /usr/local/bin. Making myself root solved this problem but now I can't run the gnuradio software except as root. Even when I use 'sudo' to run usrp_oscope.py, I get the error ImportError: libwx_gtk2d_xrc-2.6.so.0: cannot open shared object file: No such file or directory The file is in the /urs/local/bin and my LD_LIBRARY_PATH is set to that location. I set the same environment variables for both my regular user and root. If I don't use 'sudo' I get even more errors. I think that they are related to usb access. I try to use the fstab per another post and it did not seem to help. Michael A.
