Issue while installing GR 3.7

musicdenotation · February 20, 2014, 11:00pm

Hello GR,

While building GR 3.7 (clone it from
GitHub - gnuradio/gnuradio: GNU Radio – the Free and Open Software Radio Ecosystem)
on a Centos machine I got this error.

In file included from
/raid/nae/gnuradio-3.7/gr-blocks/lib/message_strobe_random_impl.cc:27:
/raid/nae/gnuradio-3.7/gr-blocks/lib/message_strobe_random_impl.h:48:

make[1]: *** [gr-blocks/lib/CMakeFiles/gnuradio-blocks.dir/all] Error 2
make: *** [all] Error 2

I did not figured out how to solve this issue .
Any hints will be appreciated.

mt19937 refers to the standard mersenne twister random number
generator used in boost; so this is your compiler complaining about
boost::random not having that. Which version of boost does your centos
machine have?

Should be
Just as side info:
http://www.boost.org/doc/libs/1_54_0/doc/html/boost/random/mt19937.html

Sorry, totally running low on clues here…
This is twice as strange since boost::random is missing mt19937; if it
was std:: I’d guess on a non-C++11 standard library, but like it is…
If cleaning and rebuilding doesn’t help, make sure that libstdc+±devel
is correctly installed

Basically, it should be right here:
http://www.boost.org/doc/libs/1_54_0/boost/random/mersenne_twister.hpp
and is included.

AAAAAAAAAAAND bam.
Found the bug. header include protection by #ifdef at the very beginning
of the file.
you might pull my bugfix from
GitHub - marcusmueller/gnuradio: GNU Radio;

git pull GitHub - marcusmueller/gnuradio: GNU Radio
master_fix_message_strobe_random_ifndef

Greetings,
Marcus

naeo · February 21, 2014, 4:02pm

Thanks Marcus,

Actually the boost version I have is 1.54.0.

Is this ok ?

Ruecan:
I got carried away. This is indeed a bugfix for the header file not
being processed in some cases, but since the error appeared although
actually processing the fixed header file, I’ve run out of ideas, still.

naeo · February 21, 2014, 5:26pm

Yeah, start completely clean.

Very Respectfully,

Dan CaJacob

naeo · February 21, 2014, 5:18pm

I just pulled the changes then did make but get the same error.

I am not so familiar with git. After pulling your bugfix, do I need to
make
clean, remove the CMakeCache then do cmake again then make or am I
missing
some part of the process.

good find, this was probably my fault - sorry
We should consider changing headers to use “#pragma once” which is
simpler and less error prone
do people still use gcc older than 3.4 ? I think this is pretty widely
supported now
not sure if that would cause swig issues as well -

naeo · February 21, 2014, 5:59pm

Guys,
I re make from clean but still got the same error.
PS: after pulling the bugfix, do I need to execute any other command,
other
than

*git pull GitHub - marcusmueller/gnuradio: GNU Radio
master_fix_message_strobe_random_ifndef *

Tim, I did not get what you mean by

Well don’t worry, it wasn’t actually causing problems

After fixing, I got out my zsh-foo and tried
echo $(( $(git ls-files |grep .h$|xargs git grep --heading “#ifndef
INCLUDED”|wc -l) - $(git ls-files |grep .h$|xargs git grep --heading
“#ifndef INCLUDED”| uniq | wc -l) ))
luckily, there are no duplicate lines containing #ifndef INCLUDED, so
I’m hopeful enough everything else is fine in current master.

I agree on the #pragma once suggestion, and choose to believe
pragma once - Wikipedia which says that we
should maybe suggest that people move away from gcc 3.4.
Although I don’t think this would break a relevant numbers of GNU Radio
environments, it could be something maintainers might want to save up
for 3.8 or 4

Greetings,
Marcus

naeo · February 21, 2014, 6:02pm

Hi Ruecan,

this just the question if we should move away from

#ifndef INCLUDED_FILENAME_OF_HEADER_H
#define INCLUDED_FILENAME_OF_HEADER_H

#endif

to the more sanity-ensuring

#pragma once

preprocessor directive.

Sadly, this was not related to your problem…
Still have no idea what’s causing your problems.

Greetings,
Marcus

naeo · March 21, 2014, 9:59pm

Has anyone found a fix for this? I will not be using the
message_strobe_random block and am very time limited, so I simply added
an #ifdef DO_NOT_BUILD at the beginning of the cc and h files, but
would like to know the correct solution.

Thanks,

Kevin

naeo · February 21, 2014, 9:26pm

Do you think that if I go back and try to install GR 3.7.0 instead, it
may
work ?

Incredibly simple fix. In
./gnuradio_src/gr-blocks/lib/message_strobe_random_impl.h, change:

  boost::random::mt19937 d_rng;

to:

  boost::mt19937 d_rng;

Done.

I’m on CentOS 6.5 and just hit this same issue – the default version of
boost for this rev of the OS is 1.41.0-18.el6 – it does appear to be
there,
but I get the same error as the original poster did (I used the

build-gnuradio script).

From the header (/usr/include/boost/random/mersenne_twister.hpp):
/typedef random::mersenne_twister<uint32_t,32,624,397,31,0x9908b0df,11,
7,0x9d2c5680,15,0xefc60000,18, 3346425566U> mt19937;/
