I am installing GNU Radio from this link :  
[http://blogs.bu.edu/mhirsch/2012/07/installing-gnu-radio-in-ubuntu-12-04-x64/comment-page-1/](http://blogs.bu.edu/mhirsch/2012/07/installing-gnu-radio-in-ubuntu-12-04-x64/comment-page-1/)  
but I got this output in terminal :

“This script will fetch Gnu Radio version 3.7/maint from the

You can change that line in the build script from  
[http://git.gnuradio.org/git/gnuradio.git](http://git.gnuradio.org/git/gnuradio.git) to  
[GitHub - gnuradio/gnuradio: GNU Radio – the Free and Open Software Radio Ecosystem · GitHub](https://github.com/gnuradio/gnuradio.git).

I just tried this and it works. It looks like the URI you were trying  
had a period after .git, which would cause it to not work. Make sure  
the URI doesn’t have a period at the end exactly like this: git clone  
–progress [GitHub - gnuradio/gnuradio: GNU Radio – the Free and Open Software Radio Ecosystem · GitHub](https://github.com/gnuradio/gnuradio.git)

I didn’t follow what you did there, but it doesn’t sound helpful.

Yes , I tried it again & it works 🙂  
Thanks Tom , Volker & Nathan .  
I ran gnuradio in terminal after installing & I see there is no problem  
in  
it

Showing: “”

BUT when installing it , after 3 hours of installation , I got an output  
which shows that GNURADIO\_CORE & GRUEL LIBRARIES are not found ! is  
there  
a problem , or these libraries are not important ? Do I have to  
uninstall &  
install again?!  
also it is saying : "You will not be able to access your USRP1 device  
until  
you do this… " … I will use B100 & B200 , is there any problem ? Any  
problem will occur when using my usrps?!

also it is saying : " You should probably set your PYTHONPATH to:

what is the importance to do that ,as I ran gnuradio now ? I found a  
.bashrc file in home directory , is this the meant file? I will copy  
paste  
“export PYTHONPATH=/usr/local/lib/python2.7/dist-packages” to the end of  
file , tell me if this is not right.

Thanks &  
Here is the output in terminal during installation:

Also, YES, set your PYTHONPATH as directed.

You should probably learn a bit about being a Linux user–we can’t  
possibly take on that role on this mailing list. Environment variables  
(such as PYTHONPATH) are a “natural” thing in the Linux world, and  
learning where/when to set them is important general Linux knowledge,  
not specifically related to Gnu Radio. In THIS case, you need to set  
the PYTHONPATH to include the location where the gnuradio installer  
installed all its bits and pieces, or Python won’t be able to find  
them, and things won’t work.

Since the build-gnuradio script has no way of reliably editing-in the  
necessary PYTHONPATH setting into your .bashrc, it gives you a printed  
notice giving you hints about what to set it to, and where.
