gqrx-sdr crashes on startup

[Robert Grasböck]

If gqrx is started, it crashes during startup.

It seems it is a problem with boost and the rest.
Maybe an upgrade to version 2.6 will fix the issues?

Status changed to 'Confirmed' because the bug affects multiple users.

Unfortunately it affects me too:

(reproducible on two different machines)

[misko (michael-wagner-gmx)]

This bug was discussed on the github of gqrx,( https://github.com/csete/gqrx/issues/452 )
There, following workaround was found:
Recompile gr-osmosdr from sources, but diable UHD-support -> then gqrx works (at least with RTL2838 DVB-T-Sticks).
So, the bug seems to be there, and not in gqrx.

[flux242 (flux242)]

if you have compiled gr-osmosdr yourself and still nothing works then it could be becase there's another lib installed in the /usr/lib/x86_64-linux-gnu

solution:

sudo mv /usr/lib/x86_64-linux-gnu/libgnuradio-osmosdr.so.0.1.4 /usr/lib/x86_64-linux-gnu/libgnuradio-osmosdr.so.0.1.4.sav

sudo ln -s /usr/local/lib/libgnuradio-osmosdr.so /usr/lib/x86_64-linux-gnu/libgnuradio-osmosdr.so.0.1.4

[DooMMasteR (winrootkit-w)]

I am also affected, I rebuild gnuradio with the defaults on my machine and everything works fine.
So I think the package is broken, but would like to know how this happened...

[gadLinux (gad-aguilardelgado)]

Affects me also...

[Henning Meyer (henning.meyer)]

This crash is caused by a C++ ODR violation between libuhd.so.003 and libgnuradio-blocks.so.3.7.10 both of which implement the virtual class boost::asio::detail::task_io_service but the implementations are not identical

[Henning Meyer (henning.meyer)]

since gqrx does not actually use boost::asio functionality in libgnuradio-blocks, the following workaround prevents crashes:

```
set LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libuhd.so.003
gqrx
```

without the need to change libraries on the file system

[Henning Meyer (henning.meyer)]

of course, the maintainers of libgnuradio and libuhd should figure out which library is at fault (i.e. built with non-standard compile options or boost versions) so that this does not happen again

[Henning Meyer (henning.meyer)]

I looked at the build logs and gnuradio is build with the flag std=c++98 while g++ defaults to std=c++14 and libuhd uses the defaults.

[Henning Meyer (henning.meyer)]

gnuradio in Ubuntu 17.10 will be built with std=c++11 hopefully that will avoid the problem.

[Alexandru Csete (alexc)]

Hello,

It looks like this problem has been resolved. At least I no longer see this problem in Ubuntu 18.04 even though UHD support is enabled.
