Hi Juan,
now I understand better what is going on. So before going to bed:
please correct me if I'm wrong:
* You had a working GNU Radio + UHD installation that suddenly stopped
working last week
* You installed this from the Ubuntu packages (?)
* Then you tried different source builds of GNU Radio and all crashed.
I don't know what caused this, but it could be a compatibility issue
between UHD headers and binary libraries.
In this case, the first step would be to make sure you have a clean
system: please uninstall all uhd and gnuradio builds and binaries and
try to make sure none of these installations linger.
Then: decide whether you want to go the self-built route or the binary
route. This decision might depend on the version of GR you want to
use: if you want to learn GNU Radio, use 3.7, but if you need to
support older code, you might want to go for 3.6.; you can't use
modules designed for 3.6 with 3.7.
Install then UHD + GNU Radio either from your package directories, or
install and build UHD und GNU Radio using pybombs simultaneously.
All the best,
Marcus
