[Discuss-gnuradio] GRCon2017 program and presentations ?

2018-10-08 Thread Jean-Michel FRIEDT
I had bookmarked www.gnuradio.org/grcon-2017/program/grcon17-presentations for accessing the GNURadio conference 2017 program and I believe slides of the presentations. This page is gone, and I cannot find an alternative: is there a place where these documents might still be found ? Thanks,

Hi Luis - The tag is probably "v3.7.14.3" (with the extra 'v' in front); that's the way it looks like its listed on GitHub: < https://github.com/gnuradio/gnuradio/tree/v3.7.13.4 >. Either way, this script is outdated & PyBOMBS is a modern, kept-up-to-date way that's the better alternative for

Re: [Discuss-gnuradio] A question about the 'next' branch

2018-10-08 Thread Michael Dickens
Hi Carles - Shortest answer: yes. Longer answer: 'next' was merged into 'master' ['next' is dead, long live 'next'!] ... 'master' now contains the whole future of GR; there is not more 'maint' or 'next' (even if they still exist, they are deprecated), just 'master'. - MLD On Mon, Oct 8, 2018, at

Hi there, I've seen that recently there are merges to the 'master' branch which also apply to the 'next' branch, but the last commit there is from more than one month ago. I was using the 'next' branch to make sure that our blocks will be ready for GNU Radio 3.8 whenever it is released. Should I

Hi Luis - So the issue is that the installed version of Volk isn't API compatible with that required by GR. I believe that GR is too old, and you should use a more recent version. This script will try to build by default from "3.7/Maint", which is obsolete though it might work. The other "easy"
