LTE framework receiver gr-lte

musicdenotation · December 2, 2013, 1:42pm

Hi,

I tried to compile gr-lte package from github (version 3.7 not master),
but it doesnt’t work. GRUEL and GNURADIO_CORE have been still there.
I removed GRUEL and replaced GNURADI_CORE with GNURADIO_RUNTIME,but it
is still not working. Has somebody experience with this package?
Thanks!

thanks a lot!

Hi,

on branch gr37 there are 2 directories with code. The ‘code’ directory
contains GR 3.6 blocks for reference and gr37-lte contains the new 3.7
API
blocks. 3.6 API blocks will eventually be removed as soon as it seems
fit.

Happy hacking

Hi,

I gave it a try, but it misses something with libfftw3.

It is missing libfftw3f. Or more specific a make target. Anyway, as
libfftw
is a GR dependency it is not explicitly listed for gr-lte. Just to make
things sure. Check if libfftw3 is installed.

Baier · December 3, 2013, 9:53pm

Sorry, forgot to mention it, of course it is installed. libfftw3-3 with
dev and dbg, from the normal packet management. OS is Kubuntu 12.04 LTS
32 bit, GR3.7 installed and working, uhd, gr-osmosdr, bladerf.

the library path to libfftw3f is actually hardcoded in the makefile.
search for
SET(FFTW3f /usr/lib/x86_64-linux-gnu/libfftw3f.so)
in gr37-lte/lib/CMakeLists.txt
and replace it with the the proper library location for your system.
for example:
SET(FFTW3f /usr/lib64/libfftw3f.so)

best regards,
Martin

Hi Ralph,

If you come up with a sane solution for this, let me know. This hack is
a result of getting stuck in CMake hell while being in a hurry.

Ah, I see, the comment for this tells something about an ugly hack, and
it seems I fell for it

Thanks!

Baier · December 4, 2013, 1:58pm

Well, I’m an RF guy, not a programmer, sorry But maybe even a dumb
script could check the path and modify the file accordingly? Would also
be an ugly hack, but at least almost no one would notice

Hi Johannes,
for me, this was quite trivial: Just use the original GNU Radio
cmake/Modules/FindFFTW3f.cmake, and include it in your toplevel and
lib/CMakeLists.txt
For reference, see my gist for example CMakeListses; watch out,
however, this is modified to use the double precision fftw methods;
replace FFTW by FFTWf unless you need double precision. Use the
original FindFFTWf.cmake if you want single precision float!
