Re: [Discuss-gnuradio] Ubuntu: Pybombs install UHD hangs at 6%?

[Eamon Heaney]

Thanks all, it makes sense that I'd be running out of memory on an old Pi. Looks like my swap space was only 128MB, so maybe I'll bump that up just in case.

And thanks for the link, Chris; I should be able to get my hands on a Pi 3 with 2GB ram, hopefully that'll cut compile time.

It's not hanging at the install, it's hanging during the build.

With that little bit of pedantry out of the way, I'm going to *guess*
that you're running out of RAM and starting to hit swap. `htop`,
`top`, or `free` would show you if you're swapping. If that's the
case, you could try turning down the the number of parallel jobs to 1,
eg. only 1 gcc process at a time. This might allow the compile to
succeed. You might also need to reduce optimization levels. It sounds
a lot like you're having much the same problem as this guy
(https://www.raspberrypi.org/forums/viewtopic.php?t=169608) ... 6hrs
down to 7minutes when he's not getting swapped to death.

GDB has a 'break' feature; why doesn't it have 'fix' too?
