Hi Marcus,
Thanks for the detailed instructions (and don't worry I understood the SWIG
comment ;-) )
I did as you suggested and the Boost warning DID disappear - and it was only
necessary to put the new FindBoost.cmake file in the gr-tutorial/cmake/Modules
directory.
However, unfortunately that didn't - so far - stop the Attribute Error. Maybe I
should scrap tutorial 4 and rebuild the flowgraph from scratch, as I first of
all actually opened the grc with it already loaded (that was unfortunate and
just because that was how I closed it on Friday actually) and got some
library/program conflict messages, please see in attached 'output run grc'
file, but I suppose that's just due to the Boost changes?
Then I did replace the module in the flowgraph but still get the Attribute
error when I try to run it. I am using QT gui - I don't understand why it is
mentioning 'wx-python' in the warnings but that may not be an/the issue ?
I will be grateful for any suggestions although I may not be able to try any of
them out until Wednesday.
Regards
Jacqueline

Subject: Re: [Discuss-gnuradio] Module attribute error in C++ guided tutorial
Hi Jacqueline,
first of all: thanks for the excellent report! It's rare that we get such
well-defined and -researched problem descriptions.
So, regarding SWIG, I guess "everyone" is about as smart as you are. I don't
get that warning, though I'm using the same version of SWIG as you are - also,
the same version of GCC. What differs between our systems (mine is a fedora 25)
is that you're using a more recent Boost version - as we see from the errors,
somethings amiss with that.
Now, Boost has a history of not having good autoconf and CMake scripts, and
that could be exactly what's hurting us here - the FindBoost in my
/usr/share/cmake/Modules has exactly the warning displayed at exactly the code
line (744), but it also as a terrible long list of elseifs() before that simple
ends for 1.62 - it seems that at least for my CMake Version, no one had the
time to fix Boost detection. Luckily, that seems fixed upstream [1]!
Can you do two things:
1. go into your /usr/share/cmake-3.7/Modules/FindBoost.cmake , line 744, and
verify the last elseif is "NOT Boost_VERSION VERSION_LESS 106100 AND
Boost_VERSION VERSION_LESS 106200" ¹
2. if 1. is the case, go to [1], replace (maybe backup) your FindBoost.cmake
with that (maybe putting it in your gr-tutorial/cmake/Modules directory
suffices, here, but I'm not sure in which order cmake goes through the
different directories) , empty your build dir (really, rm -rf
gr-tutorial/build/*) and do things again. Does the Boost warning disappear? If
it does, would be a nice time to let the upstream maintainer of Arch's Boost or
Arch's cmake package know that this file needs updatin'.
3. Try again with tutorial 4.
Best regards,
Marcus

¹ somehow I feel someone missed the meaning of "elseif" here, but that might
just be me

Hello again,
Working through the python programmed modules in the guided tutorial and no
problems but I get the same 'module attribute error' trying to complete the C++
tutorial.
Following directions exactly, files compile, block appears in GRC, can build
the flowgraph but get the same execution error.
Please see text files attached with the error output and the outputs of the
cmake.. and make commands. Obviously, there are warnings etc. that do not
appear in the sample output as described in the tutorial. Could these be the
cause of the error? I could not find any helpful information on swig warning
302 for example beyond what it roughly means.
As before running on a completely up-to-date Archlinux 4.8.13 and GRC 3.7.10.1.
I have removed and rebuilt everything several times but nothing works.
Thanks for any suggestions,
Jacqueline
