[Discuss-gnuradio] what things does UHD do?
Hello everyone here, I find if I do not use UHD, for example, when I use gnuradio-3.3.0 to transmit files, the "ok=flase" when I set the bitrate greater than 600K or less than 300K. However, when I install UHD and use gnuradio-3.5.0, I find I can use the bitrate from 1M to 5M, why the uhd can lead to the difference when I use the same modulation method? I get bitrate from the URL: http://www2.engr.arizona.edu/~junseok/usrp2_bandwidth.html Bitrate(symbols per second)=convert_rate/inter/sample_per_symbol The convert_rate is decided by the DACs, the inter and sample_per_symbol is set by gnuradio, does them lead to the difference? Any guidance will be appreciated！ -- Ding, Yuzhen Best Regards! ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
Re: [Discuss-gnuradio] Unable to compile gnuradio under MSVC - missing stdbool.h
Dear Josh,
I updated my cmake to latest 2.8.9 (I had 2.8.4 one). I have had to
remove the macro #if !COMPILER(MSVC) #error ... of stdbool.h this #error
was being thrown every time. I do not know why this macro is false, but
now volk compiles.
However, it seems the other projects do not find stdbool.h. Looking in
include_dirs volk/cmake/msvc is not included. So, I have copied
volk/cmake/msvc/stdbool.h to cmake/msvc and everything works ok.
I recall I use cmake 2.8.9, MSVC 2012, Windows 7 x64.
Nevertheless I have few more errors:
- I do not have gsl and gnuradio-wavelet fails on finding gsl/gsl_errno.h
- 'make' declarations in wavelet_ff.h, squash_Ff.h and wvps_ff.h cannot
be declared with dll interface (error C2487: member of dll interface
class may not be declared with dll interface)
- fcd_nfm_rx cannot find libboost_program_options-vc1000-mt-1_49.lib (of
course I have it). Libpath does not include boost path.
- gnuradio-filter displays undefined symbol gr_rotator::gr_rotator(void)
and other related methods (gr_rotator::rotate(), etc.)
- gnuradio-digital also displays undefined symbol
gri_lfsr::gri_lfsr(void) and other related methods (next_bit, etc.)
Other projects work very well.
Thanks.

Any idea why MSVC is not defined? Thats critically important
if(MSVC)

I use MSVC 2010 and cmake 2.8. Setting MSVC seems to be the standard
thing to happen when you configure the project to use MSVC.

In addition, if I change GR_CORE_API of gr_rotator.h for FILTER_API it
compiles correctly.
