Re: GNURadio 3.7.14.0 Building gr-video-sdl

[Marcus Müller]

Hi Mitja,

there's more going on here, gr-video-sdl has been part of GNU Radio for a long, long time. 
Since at least GNU Radio 3.3, in fact; some 15, 16 years.

So, your version of 3.7 would definitely also include it, and you should not try to 
backport a more modern version to it.

So, we need to solve your actual problem than you trying to backport gr-video-sdl from 
3.7.14 to a different version of GNU Radio.

So, what *is* your current version of GNU Radio, where does it come from, why does it not 
contain gr-video-sdl?

Note that as maintainers, we'll have a really hard time helping you with GNU Radio 3.7; 
it's end-of-life, so most of us aren't even trying to build it on our machines.

You also seem to be mixing PothosSDR stuff with GNU Radio includes, and I don't know 
whether that is just meaningless paths or whether you're actually confusinge something?

Best regards,
Marcus

PS: Others might have told you that already, but it might really be worth pointing out 
that living in the 3.7 world might be increasingly hard, and we're sorry about that, but 
it's just technologically mostly obsolescence why we're not able to support it anymore. 
Instead of sticking to 3.7 due to "some legacy blocks" it might be worth to forward-port 
these missing blocks to GNU Radio 3.10 or 3.9, and work with a modern version of GNU Radio 
– honestly, GNU Radio has gotten *a lot* better to install under practically all operating 
systems in later versions.
