Re: [Discuss-gnuradio] gr-cdma

[Achilleas Anastasopoulos]

Another suggestion is to install your gr-cdma exactly where your gnuradio is installed.

Looking at the output of the cmake I think I know what is going on:

Your gnuradio installation is not in the standard directory /usr/local/...

So probably your PYTHONPATH variable is not set for python to look there.

You should add the directory

/usr/local/lib/python2.7/site-packages/

in your PYTHONPATH

Ekko,

Do not worry about grc for now. You first have to fix the python import error.

It is very unusual that you have downloaded the gr-cdma in the directory    "/home/gr-cdma" .

In the /home directory usually there are user directories and you do not have permissions, etc...

How do you run all these (as root?) you should not...

Please do me a favor and try the following:

As a REGULAR user (ie, not root) go to your home directory (say /home/ekko for example) and download gr-cdma there.

Then change the cdma_parameters.py file to indicate the new prefix=/home/ekko/gr-cdma

Finally can you verify that python looks at these directories:
/usr/local/lib/python2.7/site-packages/

If not, you should set your PYTHONPATH.

Also, I wanted to ask you: do you have a working GNURADIO installation?

Where is it?

Are your remaining gnuradio blocks also residing in
/usr/local/lib/python2.7/site-packages/ directory?

hello achilleas

thank you

the next is mine operation and result 

step1:i modify the cdma_parameters.py

vim cdma_parameters.py

the result is picture1 

i am sure the prefix is right

step2:

mkdir build_cdma

cd build_cdma

cmake ../

the result is

1. load  amp_var_est_hier.grc and generate ,exe

when i reload this grc i got that

XML parser: Found 3 erroneous XML files while loading the block tree (see "Help/Parser errors" for details)

2. load cdma_tx_hier.grc

i got the result in picture2

and the detail of import box is picture3

then i stopped 

wait for your reply

Ekko,

I can help you with these error messages. They are not supposed to appear.

Can you describe in detail the results from the steps you followed to build/install gr-cdma.

They are described in the README file of gr-cdma. There are 3 precisely defined steps.
