Hi Nemanja,
ha! I wish that was true! Usually I'm not right, trust me.well Marcus, you were right (like usual) ...
I tried GRC and it worked. What was strange for me is that flowchart was not terminated when I closed QT scope.That's a bit surprising; you don't happen to have a .grc with which I can recreate that?
Cheers,
Marcus

What was strange for me is that flowchart was not terminated when I closed QT scope.As for the min test, it doesn't work, it just stays blocked, no particular output.I don't know what exactly problem was, but concerning GRC, it looks like in my first attempt to buld sphinx executable couldn't be found.Hello,well Marcus, you were right (like usual) ...

First, try to run the test in isolation:
in your build/ directory,
ctest -V -R min
should run your test alone. If that doesn't give you additional insight, try running
./gr-blocks/python/blocks/qa_min_test.sh
directly.
You should also inspect the reason GRC core dumps, there's a small wiki page for that [1]; but to be completely honest: qa_min failing and GRC segfaulting sounds like there's some mismatch between the libraries used at build time and the libraries loaded at run time, in my experience.
Best regards,
Marcus

NemanjaHow can I trace more what cases this error. Few days ago I built gnuradio usinc anaconda python, but had some issues with graphics and then I moved back to my native python.No, my previous Gnuradio installation is there, but with another prefix. My machine runs on RHEL6, so can't really change python cause, it makes a lot of trouble with administrators.Yes, when I remove keyword argument it finishes with core dumped.Hi,as for the test, I didn't copy correct lines. My test literally blocks in test 11 and never get out of that.

Hi,
I think this is what that test is supposed to look like, so reading that is a good sign!
You say you get a segfault when running GRC, right? That's a bit surprising, because GRC is pure Python, so it's probably something that gets loaded along the way. Have you uninstalled your previous GNU Radio installation?
By the way, I thought pre-2.7 Python was practically extinct; out of curiosity: which OS are you on?
Best regards,
Marcus

Hi!
First intuition is that there might be something wrong with the Python version in use. Which is it? Python pre-2.7 doesn't know the keyword arguments, so it would have to read
.decode('utf-8','replace')
Instead of
.decode('utf-8',errors='replace')
Cheetah is, as far as I know, not Python 3 compatible.

It looks like Cheetah problem but can't make it work. There was suggestion few years ago to remove errors='replace', but it didn't work for me.
