View all threadsProblem updating uhd library on Ubuntu 20.04
Hi all,
I am working with gnuradio and usrps on an ubuntu 20.04
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.4 LTS
Release: 20.04
Codename: focal
I usually update my uhd libraries from ettus binaries as described here:
https://files.ettus.com/manual/page_install.html
$ sudo add-apt-repository ppa:ettusresearch/uhd
$ sudo apt-get update
$ sudo apt-get install libuhd-dev libuhd4.1.0 uhd-host
Then I usually build gnuradio from source (I am currently in v3.8).
I DO NOT install gnuradio from repositories!
Today I tried to update the uhd libraries.
First I cleaned up all previous versions:
$ sudo apt-get remove libuhd-dev libuhd4.1.0 uhd-host
$ sudo apt autoremove
$ ldconfig -p | grep uhd
libgnuradio-uhd.so.3.8.5git (libc6,x86-64) =>
/usr/local/lib/libgnuradio-uhd.so.3.8.5git
libgnuradio-uhd.so.3.8.4 (libc6,x86-64) =>
/usr/local/lib/libgnuradio-uhd.so.3.8.4
libgnuradio-uhd.so.3.8.3git (libc6,x86-64) =>
/usr/local/lib/libgnuradio-uhd.so.3.8.3git
libgnuradio-uhd.so (libc6,x86-64) =>
/usr/local/lib/libgnuradio-uhd.so
Then I tried to install the uhd libraries:

I want to just update my uhd to the latest version from ETTUS repositories
and then build gnuradio from source as I used to do.

thanks in advance,

YOu could perhaps just install the .deb file from here:
I guess APT is satisfying your request from the main repo in preference
to the PPA. Not sure why, but installing the .deb directly might help?

$ sudo apt-get install libuhd-dev libuhd4.1.0 uhd-host
Then I usually build gnuradio from source (I am currently in v3.8).
I DO NOT install gnuradio from repositories!
Today I tried to update the uhd libraries.
[...]
$ sudo apt-get install libuhd4.1.0
[...]
Now I am trying to install the "uhd-host" library:
$ sudo apt-get install uhd-host
[...]
*The following additional packages will be installed: libuhd4.2.0
[...]
*******I do not understand why it asks to install also the
libuhd4.2.0 library.
The UHD version from the PPA for focal is 4.2, not 4.1.
The issue here is that you first installed an outdated version
of the library before installing uhd-host (libuhd4.1.0).
You should have installed libuhd4.2.0 instead.
If I do that, then I get the following errors:

Yeah, for some reason,
dpkg/apt does not consider libuhd4.1.0 and libuhd4.2.0 being
two version of the same package (libuhd).
I think that a known issue (or feature?) on Ettus side.
Alternatively if I try to remove "libuhd4.1.0" and install the latest
"libuhd4.2.0"
[...]
Now I can easily install the "uhd-host" library
[...]
BUT, when I try to install the "libuhd-dev" library I get the following
which
I suspect wants to install the entire gnuradio system from the repository,
which as I said in the beginning I do not want, since I am usually building
it from source.
$ sudo apt-get install libuhd-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following additional packages will be installed:
freeglut3 gnuradio gnuradio-dev
[...]
libuhd3.15.0
[...]
Can anyone help with this?
IMO, that's a dependency issue.
libuhd-dev has gnuradio-dev as recommended package,
and AFAIR, apt installs recommended package by default.
Apt tries to solve the deps+recommend for libuhd-dev_4.2 (from the PPA),
but it cannot find a compatible gnuradio-dev package
(the only gnuradio-dev package it can find is from the Ubuntu focal repo,
which is built upon UHD 3.15.0).
So apt tries the libuhd-dev package with a lower priority,
i.e. the one from Ubuntu focal repo.
Maybe this will work:
sudo apt-get install --no-install-recommends libuhd-dev
or
sudo apt-get isntall libuhd-dev gnuradio-dev-
