gqrx crashes with FCDP+

piranha32 commented 11 years ago

gqrx crashes on starting DSP. Output from the program:

Please see issue #91

csete commented 11 years ago

Of course, feel free to reopen if you think you have found a different issue.

piranha32 commented 11 years ago

I'm not sure if it deserves reopening, I'm aware of the bandwidth issues, but the "'fcd_source_c': output 0 is not connected internally" message looks different enough from the other issues that I thought it deserves own case. I haven't seen any BW related messages. You know the program better, so if you think that it's just another manifestation of the bandwidth hydra, I'm fine with closing it.

csete commented 11 years ago

The "not enough bandwidth" messages appear in the syslog either when you plug the dongle in or when you start DSP. Type dmesg in a terminal to see the messages.

If you don't see the bandwidth messages we can take a closer look at it, but I am going to need much more info than this generic error message, e.g. which version of gqrx this is and how did you installed it, the same for gr-fcdproplus.

piranha32 commented 11 years ago

No "Not enough bandwidth", but I see ALSA complaining about inability to get freq:

csete commented 11 years ago

Ok, thanks. Sounds like a different issue so I reopen the issue but I will first be able to look at it after 2.2 is released.

csete commented 11 years ago

Just to be sure, you do have an udev rule for the Pro+? It has different product ID than the Pro and needs its own entry.

piranha32 commented 11 years ago

I didn't have rules for Funcubes, but adding them (from https://raw.github.com/csete/qthid/fcdpp/funcube-dongle.rules) did not help. Still "cannot get freq" and gqrx crashes.

csete commented 11 years ago

If you download this .tar.gz file: https://launchpad.net/~gqrx/+archive/snapshots/+files/gr-fcdproplus_0.0.1%2B1git20130802-g2ba97709-0ubuntu0%7Egqrx%7Eraring9.debian.tar.gz you will find a libgnuradio-fcdproplus.udev file in. Please try that rule as it may work better.

csete commented 11 years ago

PS: I don't know if necessary, but you better rename the file to have .rules extension.

piranha32 commented 11 years ago

I added the rule and commented out FCDP+ from the old file, but gqrx still crashes. The link in /dev is created, so the new rule has been applied. Gqrx also crashes when started from root account, so it doesn't look like a problem with permissions.

piranha32 commented 11 years ago

It looks that the problem is with gr-osmosdr. From my experiments with gnuradio-companion:

The FCDP+ source block works fine.
osmocom source works when it thinks that it talks to FCDPv1. Enforcing FCDPv2 by appending "type=2" to device arguments crashes the flow graph with "output 0 is not connected internally" error message.

Which version of gr-osmosdr do you use?

csete commented 11 years ago

for the official gqrx release I have packaged git version from 20130728 g9dfe3a63. You should get an error message when you configure gr-osmosdr with FCDPv1 since it has differetn product ID than the v2 (you shouldn't be able to set frequency and such).

osmocom does not detect properly FCD when I provide 'device=' parameter. Then FCD is assumed to be v1. When 'device' is omitted FCD is detected properly, but the block crashes. When I enforce device and FCD type the block crashes as well. The flow graph is very simple: source + null sink, so there is not much else to crash. Log from grc. Run as root, to avoid potential problems with permissions:

Device configuration string for osmocom source:

fcd=0

Still a problem, but it's not a problem with gqrx so I'm closing the issue. Feel free to reopen if you think that you can do something to fix it.

FWIW I usually use device string like this:

fcd,device=hw:2,type=2

piranha32 commented 11 years ago

With fcd,device=hw:1 even a microphone is detected as FCDv1. Adding type=2 always crashes the application. Can you post somewhere statically linked version of gqrx, so I wouldn't have to depend on my libraries?

csete commented 11 years ago

I have uploaded a binary package to sourceforge: https://sourceforge.net/projects/gqrx/files/2.2.0/ I hope you can use it.

piranha32 commented 11 years ago

I'm missing some libs. Could you please add them to the package?

[jacek@dragon32 gqrx-2.2.0-x86_64]$ ldd ./gqrx |grep "not found"
        libIce.so.34 => not found
        libIceUtil.so.34 => not found

Can you try to install zeroc ice 3.4 package?

piranha32 commented 11 years ago

Works. For the record:

I've downloaded ICU4C from http://site.icu-project.org/download/48#ICU4C-Download and zeroc ice from http://www.zeroc.com/download_3_4_2.html
Packages to install on Fedora 19 from ice (may be necessary to remove newer packages from distribution): sudo yum localinstall ice-libs-3.4.2-1.rhel6.x86_64.rpm ./ice-3.4.2-1.rhel6.noarch.rpm ./db48-4.8.30-1ice.rhel6.x86_64.rpm
Libraries from ICU4C to copy to lib directory: cp libicudata.so* libicuuc.so* libicui18n.so* <gqrx dir>/lib
Start gqrx LD_LIBRARY_PATH=lib ./gqrx

csete commented 11 years ago

Strange... it should work without copying the libraries to lib/ and without doing the LD_LIBRARY_PATH thing.

piranha32 commented 11 years ago

I copied libraries to lib because thy were not packaged in rpm and I didn't want to copy them to /usr/local/lib64. LD_LIBRARY_PATH is not really necessary, but at some point linker didn't want to see one of the libraries, so I added it to be safe. Otherwise everything works fine. I posted the recipe as a reference for people who would like to run your binary on a system which does not provide proper versions of ice and icu4c.

gqrx crashes with FCDP+ #97
