[Discuss-gnuradio] Unable to build on 32-bit Slackware-Current system (cmake configuration problems)

[TPCgr]

Dear All,
     I am attempting to build Gnuradio on a 32-bit x86 Slackware-current system 
but without success.  I have tried several approaches.

o Using the Slackbuilds scripts at 
https://slackbuilds.org/repository/14.1/development/gnuradio/ which builds 
gnuradio-3.7.8.1.
o Using the Slackbuilds scripts to build the current release gnuradio-3.7.9.1
o Unpacking gnuradio-3.7.9.1 and following the minimal instructions at 
http://gnuradio.org/redmine/projects/gnuradio/wiki/BuildGuide
o Downloading the default branch from git and following the minimal 
instructions at http://gnuradio.org/redmine/projects/gnuradio/wiki/BuildGuide


Firstly I found and fixed/worked-around 3 compiler problems encountered with 
gcc 5.3.0;  

(1) -lpthread needed to be added to CMAKE_C_FLAGS and/or CMAKE_CXX_FLAGS.  I 
added it to both.
(2) This fix "sed -i 's/(intrin.h/(x86intrin.h/g' ../volk/lib/CMakeLists.txt" 
gets around intrin.h not being present.
(3) This fix "sed -i 's/.\+Werror=unused\-command-line\-argument.\+//g' 
../volk/lib/CMakeLists.txt" gets around this Warning option not being available.

Then I was able to start the cmake configuration process.  However I get errors 
like this,

/usr/bin/python2: can't open file 
'/tmp/SBo/gnuradio-3.7.9.1/gen/volk_compile_utils.py': [Errno 2] No such file 
or directory

This script is present but in the volk sub-directory, ie. in 
/tmp/SBo/gnuradio-3.7.9.1/volk/gen/volk_compile_utils.py.

Checking the source tarball, eg.

$ tar -tzvf gnuradio-3.7.9.1.tar.gz | grep volk_compile_utils.py
-rw-rw-r-- root/root      2165 2016-02-07 17:09 
gnuradio-3.7.9.1/volk/gen/volk_compile_utils.py

confirms this is where it gets unpacked.

I tried a couple of work-arounds,

(1) Symlinking the volk/* directories into the top-level directory before the 
cmake stage and then repeating this
symlinking in the build directory.  Doing this got me some distance (23%) into 
the make procedure before it failed.  See files gnuradio.SlackBuild.try6 & 
gnuradio.SlackBuild.try6.log.  Some of these directories already exist in the 
top level & build directories and so can't be symlinked from below.
I can't believe this should be necessary and I presume must be an artifact of 
something else being amiss...

(2) Editing the volk/lib/CMakeLists.txt list before running cmake and following 
the Wiki BuildGuide.  The following edits/hacks allowed the cmake 
to complete but the make failed soon after starting and I gave up at that stage.

sed -i 's/\${CMAKE_SOURCE_DIR}\/gen/${CMAKE_SOURCE_DIR}\/volk\/gen/g' 
../volk/lib/CMakeLists.txt
sed -i 
's/\${CMAKE_SOURCE_DIR}\/lib\/qa_utils\.cc/\${CMAKE_SOURCE_DIR}\/volk\/lib\/qa_utils.cc/g'
  ../volk/apps/CMakeLists.txt

See files tom_build.sh & tom_build.log.  Again I can't believe this should be 
necessary.  

Please see http://www.mklab.rhul.ac.uk/~tom/tmp-gnuradio.tar.bz2 for all the 
above mentioned files.


Please help/advise!
