Problem in update of GNU Radio

GNU Radio
1

Hi,

I was using the computer of my university lab and I noticed it didn’t
have the lattest version of GNU Radio. It had gnuradio 3.3.0 installed.
Then I downloaded the build-gnuradio script from gnuradio.org/ and then
I got an error when I try to use GRC:

RuntimeError: Please update the firmware and FPGA images for your
device.
See the application notes for USRP2/N-series for instructions.
Expected FPGA compatibility number 9, but got 7:
The FPGA build is not compatible with the host code build.

Then I searched on the internet and a possible explanation is the fact I
have multiple installations of gnuradio. So I should uninstall them.

However, there are gnuradio projects already done in this computer that
work with the oldest version. They still use autotools, so I don’t know
if by removing the oldest version from the computer they will stop
working.

Also, I would like to know how to uninstall gnuradio.

Isn’t there a way to work with multiple versions on the same computer?

I have a USRP2, and my Ubuntu version is 10.10

I have to have this problem solved by monday so I am pretty desperate.

Any support would be appreciated.

Also, the guys from the lab that use gnuradio put their projects in
locations like “/usr/local/bin”; The same folder where
“http://gnuradio.org/redmine/projects/gnuradio/wiki/FAQ” suggests that
all gnuradio files should be removed so I can uninstall the old version.

So basically I have 2 versions installed and I can’t remove them because
people put their projects in the folders where only gnuradio files that
come with the installation should be.

Isn’t there a way to make this computer work with both versions, or at
least a way to remove one of them without eliminating other gnuradio
files as collateral damage?

Correction: Hmm I made a mistake. the old version I had installed was
3.4.1 and not 3.3.0
