I followed the tutorial on gnuradio.org (correct link: http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorial_GRC )
This is the particular flowchart we're talking about: https://raw.githubusercontent.com/gnuradio/gr-tutorial/master/examples/tutorial2/images/tutorial_two_1.png In attachment is the .grc file.

Which one from that tutorial are we talking about specifically? Can you share the .grc file?

This installation went smooth and I did not observe any problems. After this I started to follow the tutorial ( http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorial_GRC ) but on step 2.1.2 the cmake command failed so i needed to install the cmake and doxygen packages.

The error really doesn't say anything more. We haven't seen such error in released GNU Radio versions lately. My guess therefore is that there might be something wrong with your set up instead. How did you install GNU Radio? If you've installed it from source, or build-gnuradio, or pybombs you *must not* install gnuradio from Ubuntu's package archives.

At this moment i ran into a problem: I followed the steps of the tutorial at http://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorial_GRC I made the flowchart exactly as described in the tutorial, but when i try to execute the flow graph, a window appears and directly closes. When I try to run the code directly from the terminal i get following message: Segmentation fault (core dumped) I'm running Ubuntu 14.04 LTS. How can I fix this issue?
