Re: GRC version 3.9.0.0 git master (python 3.8.2) + OOT blocks

David, 1) How is your GNU Radio installed in this system? 2) It sounds a lot like PYTHONPATH is misconfigured for OOT - where are your OOT files being installed to? Thanks, Josh On Fri, Aug 21, 2020 at 12:23 PM David Taylor (manx.net) wrote: > Josh, > > Sorry to go over old ground

of the mindset that if you want the latest released version (e.g. from the PPA), then for now you have to install OOTs from source. Except 20.04 might work. Josh On Fri, Jul 31, 2020 at 8:50 AM Paul Boven wrote: > Hi Josh, everyone, > > On 7/31/20 1:31 PM, Josh wrote: > > I think Pau

Re: apt-get breaks gnuradio 3.8.1.0

I think Paul is right - we stepped the PPA version up with the correct numbering scheme, but that seems to conflict with the dependencies of OOTs. There are a couple of ways to deal with OOTs in the future, but we don't have an immediate solution other than don't mix the PPA with the packaged

Re: OOT module AttributeError - module has no attribute Arch Linux GR 3.8.1

A lot of times the dreaded 'Module Not Found' error is caused by linker issues. In 3.8, the cmake files were modernized, but there are a few caveats especially if your OOT links against other GR modules (e.g. gr-digital). In order to use GR modules in your code, the target_link_libraries needs to
