Hi Bill,

I seen your question on python program portability. This problem can be
solved easily using one software called CDE ( Code, Data and Environment)
which will create package which you just need to carry (no need of gnuradio
for running program)

Have look at following sites:

http://crazylazy.info/blog/?q=content/please-test-gnu-radio-cde-package

http://www.pgbovine.net/cde.html

I had some experience of creating whole gnuradio as portable package
(though not 100% successful but still works in many machine). If you need
any help on this, feel free to contact me.

Hello List;

Thanks to Senthil Murugan; I have my immediate problem solved and I can
deliver the

goods to the customer. (And get paid J for the hardware development J .)

So for now the live CD is on the back burner, until I get some spare time .

Later

Hello all,

I was thinking Gnuradio might benefit from an online message board
style forum. It would be easier for beginners not familiar with the
workings of mailing-lists and would IMHO allow for easier message
traversal for people to find previously solved problem. Has there been
any consideration of this? Maybe just a help forum and development
could still happen here.

Thanks.

Hi Andrew,

Yes, this has been discussed in the past but has never had much buy-in
from the main developers in the community. We're happy and comfortable
working in the mailing list

On the other hand, if users want to take up the banner and help others
coming into the community in whatever forum you want, I have no
objection to it. And feel free to link to it on the Wiki. If it takes
off, is helpful, and becomes the standard place of conversation, it'll
prove its worth and we might have to migrate because of that.

Tom

The FILE GLOB could do the same trick as you suggest:
"FILE(GLOB qwt_files ${qwt_dir}/include/qwt*/qwt_plot.h)"

I tried to write a patch which uses exactly that.
It tries to locate the header files in:
/usr/local/qwt*/include
/usr/local/include/qwt*
/usr/qwt*/include
/usr/include/qwt*
/opt/local/qwt*/include
/opt/local/include/qwt*
/sw/local/qwt*/include
/sw/local/include/qwt*
Furthermore, the libraries are searched in the same order. So if I
have the packaged version for qwt in /usr/include/qwt5 and I have a
manually compiled qwt in /usr/local/qwt-6.0.2-svn, it prefers the
manually compiled version, and makes sure that it will then search the
libraries in exactly the same order. On 64bit machines, the lib64 will
be preferred over lib.
This patch is pure cmake language, so it should not break on windows.
Furthermore, no maintenance should be needed with new versions of qwt.

Message-ID: <005b01cd329b$718d0780$54a71680$@address@hidden>
Content-Type: text/plain; charset="us-ascii"

Hello List;

Senthil suggested I try these links, and they appear to work like a charm !

http://crazylazy.info/blog/?q=content/please-test-gnu-radio-cde-package

http://www.pgbovine.net/cde.html

Here is what I was thinking. What if someone ran GRC and the other packages
using the CDE <command> format ?

Then what you would have is a package, or two, that would run immediately on
any Linux system !

Obviously as updates come out, someone would have to build new packages. BUT
rookies could get up and running

without all the pain and suffering of dependencies and what not.

I know your script works great Marcus, but people with crappy internet
connections take forever to build this way L

So, what do you think guys ? Marcus, Tom ?

I would do it myself, but I don't have a USRPx anymore .

Bill

Subject: [Discuss-gnuradio] Trouble in running usrp_siggen.py (or
    usrp_siggen_gui.py)
Message-ID:
    <address@hidden>
Content-Type: text/plain; charset="iso-8859-1"

Good evening,

Currently, I am testing usrp_siggen.py (or gui version) with usrp_fft.py
and usrp_oscope.py
But I have a unfamiliar error message which I have never faced.

When running siggen without SU permission:
socket(PF_PACKET, SOCK_RAW, htons(0xBEEF)): Op
eth0: socket: No such file or directory

With SU permission,
eth0: SIOCGIFINDEX: No such device

The weird thing is I have connected USRP "1" not other version which uses
Ethernet port.
Thus, even though that error occurs, in my expectation, USB port works
fine, and I could see something on fft or oscope.

But, in reality, i could not see anything transmitted.

I googled for those errors, and found some solutions,
1. check usrp group, and user account is a member of group
2. usrp2_socket_opener permission is set fine (sudo chmod +s
(path)/usrp2_socket_opener)
3. give --usrp options to siggen (--usrp=usrp1)

but none of them solves this problem.
Please, someone give me an adivce.

Thank you in advance.
