GRC symbolic-link is not working‏

GNU Radio
1

Hi all,

I have installed gnuradio with grc. the bootstrap, configure, make, make
check and sudo make install all of them ran nicely. However when I type
“grc” in the terminal it says:

The program ‘grc’ is currently not installed. You can install it by
typing:
sudo apt-get install grc
grc: command not found

I tried to figure out what the problem is , and now can run grc by
double-clicking this file
“/usr/local/share/gnuradio/grc/freedesktop/GRC”.
Can anybody help me in fixing the problem, please? or maybe there’s
something went wrong in the installation caused this to happen.

Thank you,

Sam

Due to a lawsuit with the generic colorizer package (also with top-level
executable grc) we were forced to rename the executable to
gnuradio-companion.

Theres no suit. We need to start a generic colouriser awareness
campaign! Perhaps generic colouriser should rename its executable to
generic-colouriser. Its not even a good acronym…

Anyway, try it out. apt-get install grc or yum install grc
grc cat myfile.txt, it colourises the output.

You’re serious about the lawsuit? OMG.

I mean, it’s not as if three-lowercase-letters is a conceptually
“collision free space” and you were
tramping on it deliberately. Sigh.

It seems, somehow, that the libraries are going to the wrong place, I
can’t think why, I followed the instructions as best I could.

I’ve successfully installed the latest git on top of lucid.
all seems OK, except on make check I get

gr_fft_filter_ccc.cc: In member function ‘void
gr_fft_filter_ccc::compute_sizes(int)’:
gr_fft_filter_ccc.cc:133: error: ‘stderr’ was not declared in this scope
gr_fft_filter_ccc.cc:134: error: ‘fprintf’ was not declared in this
scope

I found fprintf in the indicated cc file, but haven’t got the faintest
idea how to fix. chased in the wiki, and found sa change for fprintf but
not how to fix (complete newbie to all things Linux)

I did the install anyway, and I found the USRP OK,

crw-rw---- 1 root usrp 189, 1 2010-05-31 13:48 002
Yipee!
I have an FX2400 and a basicX installed in the USRP, but that’s not of
course apparent from above.

Then

djl@usrp:~/gnuradio/gnuradio-examples/python/usrp$
./usrp_benchmark_usb.py
Traceback (most recent call last):
File “./usrp_benchmark_usb.py”, line 31, in
from gnuradio import usrp
File “/usr/lib/python2.6/dist-packages/gnuradio/usrp/init.py”,
line
25, in
from usrp_swig import *
File “/usr/lib/python2.6/dist-packages/gnuradio/usrp/usrp_swig.py”,
line
24, in
_usrp_swig = swig_import_helper()
File “/usr/lib/python2.6/dist-packages/gnuradio/usrp/usrp_swig.py”,
line
20, in swig_import_helper
_mod = imp.load_module(‘_usrp_swig’, fp, pathname, description)
ImportError: libusrp.so.0: cannot open shared object file: No such file
or
directory
djl@usrp:~/gnuradio/gnuradio-examples/python/usrp$

So, off to synaptic, and I find NO libusrp, instead there’s something
called libusrp0 installed. I’m guessing this is the problem, but don’t
know. This I know doesn’t have anything to do with the filter problem. I
took my last swig some 30 years ago, so that’s not the problem.

so, as a neqwbie, I’m stammagasted and stumped.
Is there help?

What OS, distribution, and version of compiler are you using?

It could be that gr_fft_filter_ccc.cc needs a

#include

near the top.

I have just WASTED 2 hours because of this! Why don’t you tell people
this in on the web site IN BIG LETTERS?

Our “latest git” doesn’t have an fprintf in this file (it doesn’t even
have a line 133 or 134.) This has been the case since last February
when large chunks of code were removed.

Can you run ‘git describe’ on your repo and post the output?
