Thanks Mattias, After I did-- $chmod +w .bashrc Then there is an error -- chmod: cannot access '.bashrc': No such file or directory Have you actually checked that you have a file named '.bashrc'? If you do not, its just to create one. Something like: $echo 'export BOOST_PREFIX=/opt/boost_1_37_0' .bashrc $echo 'export LD_LIBRARY_PATH=$BOOST_PREFIX/lib' .bashrc would do the trick i think... Any way, is it correct what I did changing .bashrc for solving the error when executing the grc examples? I don't really know, since I'm not familiar with GRC...

Re: [Discuss-gnuradio] Problem using GRC when executing the grc examples
You need to access .bashrc with super user rights. Open a terminal, and type the following commands: cd ~ sudo gedit .bashrc This will prompt for your password, then open .bashrc in an editable mode. A less recommended method of getting around this, would to change the access rights to .basrc with the following commands: cd ~ sudo chmod +w .bashrc -Michael Berman On Wed, Mar 3, 2010 at 4:05 AM, Makmur Hidayat makm...@gmail.com wrote: Hello, I can run some examples like dial_tone.py, audio_fft.py, and others.

The error says: Generating: /usr/share/gnuradio/examples/grc/simple/ber_sim.py Generate Error: [Errno 13] Permission denied: '/usr/share/gnuradio/examples/grc/simple/ber_sim.py' GRC generates the python files in the directory that the .grc file is found. Since the examples are installed in a root owned part of the file system /usr/share, you do not have permission to create files there as a regular user. Just open the file in grc and do a save-as in into your user home directory. Then try to run the flow graph. -Josh On 03/03/2010 04:05 AM, Makmur Hidayat wrote: Hello, I can run some examples like dial_tone.py, audio_fft.py, and others.

Re: [Discuss-gnuradio] Problem using GRC when executing the grc examples
Makmur, .bashrc is just a convenient way to set environment variables and aliases when you open a terminal. if setting theose environment variables (BOOST_PREFIX and LD_LIBRARY_PATH) before you run grc from the command line fixes your problem, then you would want to add them to your .bashrc file. Your .bashrc should be in your home directory. It should be writable by you. -Tom On Wed, Mar 3, 2010 at 7:05 AM, Makmur Hidayat makm...@gmail.com wrote: Hello, I can run some examples like dial_tone.py, audio_fft.py, and others.

Re: [Discuss-gnuradio] Problem using GRC when executing the grc examples
You need to access .bashrc with super user rights. Shouldn't ~/.bashrc be a user- override of the global /etc/bashrc (in ubuntu /etc/bash.bashrc) ? For instance if I want to change the promt to something like [hh.mm.ss]:usern...@host $ instead of the default one, I'd put those changes in my ~/.bashrc. That was always my assumption, but I might be wrong. Sorry for the off- topic, off- list, off- everything remark/question. //Mattias ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
Re: [Discuss-gnuradio] Problem using GRC when executing the grc examples
Just to clarify, this problem with the examples has nothing to do with .bashrc. Nevertheless, it is good to understand the .bashrc when working on a unix system (specifically one with bash). For your installation, just save the .grc file to a writable directory. For the future: I just pushed a branch that will generate the python file in your system's temp directory should the default directory be read-only. -Josh On 03/03/2010 09:39 AM, Tom Gross wrote: Makmur, .bashrc is just a convenient way to set environment variables and aliases when you open a terminal. if setting theose environment variables (BOOST_PREFIX and LD_LIBRARY_PATH) before you run grc from the command line fixes your problem, then you would want to add them to your .bashrc file.
