Managing dependencies for GNU radio to compile from source

  • 772

Ettus research gives a big list of dependencies for 18.04 which almost works for compiling gnu radio from source.

cmake gives the following config error:

-- Python checking for PyQt5 - found
-- Checking for module 'Qt5Qwt6'
--   No package 'Qt5Qwt6' found
-- QWT Version: 6.1.3
-- Found Qwt: /usr/lib/libqwt.so

However based on the packages I have (seems like every possible version.. perhaps too many) I should have what it needs.

apt-cache search qwt
libqwt-dev - Qt widgets library for technical applications (development, qt4)
libqwt-doc - Qt widgets library for technical applications (documentation)
libqwt-headers - Qt widgets library for technical applications (header files)
libqwt-qt5-6 - Qt widgets library for technical applications (runtime, qt5)
libqwt-qt5-dev - Qt widgets library for technical applications (development, qt5)
libqwt5-doc - Qt widgets library for technical applications (documentation)
libqwt5-qt4 - Qt4 widgets library for technical applications (runtime)
libqwt5-qt4-dev - Qt4 widgets library for technical applications (development)
libqwt6abi1 - Qt widgets library for technical applications (runtime, qt4)
libqwtmathml-dev - Text Engine for Qwt (development, qt4)
libqwtmathml-qt5-6 - Text Engine for Qwt (runtime, qt5)
libqwtmathml-qt5-dev - Text Engine for Qwt (development, qt5)
libqwtmathml6abi1 - Text Engine for Qwt (runtime, qt4)
libqwtplot3d-doc - 3D plotting library based on Qt/OpenGL (documentation)
libqwtplot3d-qt5-0 - 3D plotting library based on Qt5/OpenGL (runtime)

python-qwt - Pure Python implementation of Qwt - Python 2
python-qwt5-doc - Python Qwt5 technical widget library, documentation and examples

python3-guiqwt - efficient 2D data-plotting library - Python 3
python3-qwt - Pure Python implementation of Qwt - Python 3

How can I edit the cmake list to properly find what it's looking for?

python compiling dependencies cmake gnuradio

  1. Best Answer

    After searching the Internet for No package 'Qt5Qwt6' found, I found that the gnuradio issue tracker shows this issue, and a recommended solution:

    For the record -DQWT_LIBRARIES=/usr/lib/libqwt.so is needed on arch to make the gnuradion cmake script enable gr-qtgui.

    Here, arch refers to ArchLinux, but that doesn't mean this solution is isolated to ArchLinux and could very well work for you.

  2. I'll recommend to use APT-driven method. The GNU Radio is packaged with plugins on Ubuntu. And at first to start with using binary package as simple as:

    sudo apt-get install gnuradio

    It was packaged by compilation, the compilation requires build-time dependencies. You can get them with the following actions:

    1. Open Software & Updates (software-properties-gtk) and enable Source code repositories here

    2. Install build-dependencies with simple command:

      sudo apt-get build-dep gnuradio

      The command above will install build-time dependencies for GNU Radio 3.7.11-10 (as in Ubuntu 18.04 LTS). This version is not too new as from official site (news from 2018-07-15 contain announce of GNU Radio v3.7.13.4 Release).

    3. Get GNU Radio source of 3.7.11-10 from the Ubuntu repository with simple command

      apt-get source gnuradio

      and patch/change/update it as you want.
