3.7.5git core dumps

GNU Radio
1

Built 3.7.5git, and updated UHD to latest. Builds fine. Gnuradio from
the
command line runs fine.
When trying to run gnuradio-companion it core dumps:

~/gnuradio$ gnuradio-companion
linux; GNU C++ version 4.8.1; Boost_105300; UHD_003.007.001-84-gd99ce4ef

terminate called after throwing an instance of ‘std::runtime_error’
what(): rpcmanager: Aggregator not in use, and a rpc booter is
already

Aborted (core dumped)

Any advice?

Well, shoot. I was really hoping that was just me and something weird I
had
done to my system. I had a similar issue. I just removed my installed
version of GR, deleted all my build files, and rebuilt. If it’s still
causing you issue, you can try turning off ControlPort with
-DENABLE_GR_CTRLPORT=False in the cmake command.

I’m not sure what it is because this only happened on one of my
machines.
Potentially some weird interaction with Ice during the rebuild.

I went back to build b5006c1 , rebuilt, and gnuradio-companion is
running
again…

~gnuradio$ git checkout b5006c1

System is Ubuntu 13.10, Ice3.5

Did you try rebuilding before doing this? What was the original commit
that
was giving your trouble so we could see what’s changed since b5006c1
that
could be causing this. Frankly, that shouldn’t have anything to do with
anything.

Hi Tom,

The commit that caused the issue was 2bb2b31. I did a cmake, make, make
install after checking out that commit.

I will go back, clean out the build folder, checkout 2bb2b31 and try
again.

Hi Tom, Thanks!

Deleting the gnuradio/build directory, then rebuilding fixed the issue.

Ok, thanks. It’s possibly due to the change in commit b4bbda76 that
adjusted how one of the classes in ControlPort was defined. That should
just take clearing things out and rebuilding to fix. As I said, it’s
working fine for me now even though I saw a similar problem.
