[Discuss-gnuradio] Updating gr-specest to 3.7 |

I've spent some time recently attempting to update gr-specest to 3.7,
and I've run into a linker issue that's a bit out of my depth, any
suggestions would be helpful.
I've been following the guide published at
http://gnuradio.org/redmine/projects/gnuradio/wiki/Move_3-6_to_3-7
I have so far accomplished the following:
- Remove FindGnuradioCore.cmake and FindGruel.cmake, replaced with
FindGnuradioRuntime.cmake
that I pulled out of
gr-utils/python/modtool/gr-newmod/cmake/Modules/FindGnuradioRuntime.cmake
- Remove all GRUEL_ references and replace GNURADIO_CORE variables
with GNURADIO_RUNTIME_
- Update #include<gruel/attributes.h> to <gnuradio/attributes.h>
- Changed file structure:
- from gr-specest/include/specest-blockname.h to
gr-specest/include/specest/blockname.h
- from gr-specest/lib/specest-blockname.cc to gr-specest/lib/blockname.cc
(actually, I think that there was some significant changes that
should have been done to split
blockname.cc into blockname_impl.h and blockname_impl.cc but I'm
actually confused by all the
blockname_impl.h that are placed under include/specest, and I'm
not entirely sure that the
split didn't already happen under 3.6)
- Updated gnuradio header files e.g. '#include <gr_sync_block.h>' to
'#include <gnuradio/sync_block.h'
- Updated gnuradio classes and functions to new namespace, e.g.
gr_make_io_signature() to gr::io_signature::make()
Current status of the effort:
- Complilation errors caused by the need for above updates now worked
out and the files compile without error.
- Build currently broken, stuck at linker errors:
....
[ 52%] Built target gnuradio-specest
Linking CXX executable qa_arburg_impl
libgnuradio-specest.so: undefined reference to `fftwf_free'
libgnuradio-specest.so: undefined reference to `fftwf_malloc'
....
- Will be looking into the FindGnuradioRuntime.cmake file I lifted
from gr-utils
- Would love suggestions on how to debug this, "nm" and "ldd" show
issues but not root causes...
Future work not yet started:
- updating the gr-specest namespace to the new format
- adding new blocks: cross-correlation, normalization, running sum, etc
I've posted all my code at https://github.com/dfxx/gr-specest. Any
help tracking down the root cause of the linker errors would be
greatly appreciated. I have the feeling that it might be in the cmake
configuration, and I feel somewhat like a bull in a china shop when I
start poking around in cmake. Lots of delicate looking code in there.
