[Bug 1637774] Re: gqrx-sdr crashes on startup

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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1637774

[Bug 1637774] Re: gqrx-sdr crashes on startup

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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1637774 Title:

[Bug 1637774] Re: gqrx-sdr crashes on startup

gnuradio in Ubuntu 17.10 will be built with std=c++11 hopefully that will avoid the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1637774 Title: gqrx-sdr crashes on startup To manage

[Bug 1637774] Re: gqrx-sdr crashes on startup

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 -- You received this bug notification because

[Bug 1637774] Re: gqrx-sdr crashes on startup

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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed

[Bug 1637774] Re: gqrx-sdr crashes on startup

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 -- You received this bug notification because you are a member of Ubuntu

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... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

[Bug 1637774] Re: gqrx-sdr crashes on startup

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

[Bug 1637774] Re: gqrx-sdr crashes on startup

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. **
