Re: [Discuss-gnuradio] Error when running GRC

[Marcus Müller]

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

Hello,

I use Python 2.6.6.

When I make suggested change I got Segmentation Fault error.

I don't know if it is connected with this, but when I run test, it blocks in test n. 10. with this output:

10: Test command: /bin/sh "/scr1/nemanja/tools/gnuradio-3.7.8/build/gr-blocks/lib/test_gr_blocks_test.sh"
10: Test timeout computed to be: 9.99988e+06
10:
10: NOTE: This is supposed to produce an error from block_executor
10: Error: block_executor: propagation_policy 'ONE-TO-ONE' requires ninputs == noutputs
10: ........Using Volk machine: avx_64_mmx_orc

10:
 10/170 Test  #10: test_gr_blocks .......................   Passed    0.86 sec
test 11
        Start  11: qa_min

Can these two be connected?

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.

Hi all guys,

i built yesterday 3.7.8. When I wanted to run GRC the following error occured:

Traceback (most recent call last):

TypeError: decode() takes no keyword arguments

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.
