Problems building

I am trying to install gnuradio on Arch but I am having issues with
qtgui and pfb_clock_sync. I use qt so I need to get this figured out.

Any ideas?

The following tests FAILED:
130 - qa_pfb_clock_sync (Failed)
166 - qa_qtgui (Failed)

There were quite a few recent changes to both. But when posting
problems like this, please provide:

  • The version and architecture of the OS (32- or 64-bit)
  • The version or git commit of GNU Radio you are working off of
  • With qtgui issues, the version of Qt and Qwt you are using

I’m trying this myself on various Linux VMs I have, both 64 and 32
bit, and not coming up with similar issues.

Found a system that has the problems you described. The pfb_clock_sync
seems to be intermittent. It’s locking at two different points and so
is off by 1. That’s not a huge problem, though it shouldn’t be
happening.

The qtgui issue looks like it’s with the qtgui.sink_c and qtgui.sink_f
blocks. Everything else works fine. Working on a fix now.

Ok, fixed it. The qtgui problem was really only a problem if we didn’t
define the qApplication outside of a block, which is almost never the
case, so most applications would have been fine. But they changed a
few rules on me on how we have to treat that object. It’s explained
more in the git commit and in comments in the constructors of the
qtgui sinks.

The pfb_clock_sync issue was mostly due to being too loose in one of
the parameters. I fixed the damping factor so we are now critically
damped (previously, it was seriously over-damped) and so convergence
is faster. I think there might have also been a small flaw in the
set_history value for the _fff version of the block (which is where
the failures were occurring).

Things should be behaving properly for you now. Thanks for the bug
report.
