Error: Unknown module(s) in QT: svg

Hi all,

I am trying to build MRtrix3 on the Lin4Neuro package using Virtual box on Windows 10.
Lin4Neuro is based on Ubuntu 18.04LTS with XFCE desktop environment.
I installed libqt5sv5 and libqt5svg5-dev which are latest versions. but I’ve got some issues in configuring Mtrix3 as below.

brain@l4n:~/git/mrtrix3$ ./configure

How can I resolve this issue?
Thank you.

I think you just need to install the Qt5 SVG module:

sudo apt-get install libqt5svg5

and then try ./configure again. Let us know if that doesn’t fix the issue.

Thank you for your suggestion.

I ran command to install libqt5svg5 and got the latest version (5.9.5-0ubuntu1). Then I tried ./configure and got the following response.

  MRtrix3 was unable to locate the Qt meta-object compiler 'moc'.

  Make sure your PATH environment variable includes the location of the correct

    $ export PATH=/opt/qt5/bin:$PATH
    $./configure
  (amend with the actual path to the Qt executables on your system)

Sorry, I got that slightly wrong: you need the development version of that package (and the OpenGL module too): libqt5opengl5-dev and libqt5svg5-dev. From our documentation, this should install all the required dependencies on an Ubuntu system:

sudo apt-get install git g++ python libeigen3-dev zlib1g-dev libqt5opengl5-dev libqt5svg5-dev libgl1-mesa-dev libfftw3-dev libtiff5-dev libpng-dev

The other issue you have in your second attempt is that you’re trying to compile against a different version of Qt5 – not the Ubuntu-supplied version. It looks like that version (in /opt/qt512) was not compiled with the SVG module, which is what is causing the issue when you try to use it. I’m not sure why you’re trying to use that version, but if you have to use it, you may need to re-compile or re-install it with the SVG module.

It seems that Qt5.12 was interfering with the installation of MRtrix3. I was able to install MRtrix3 after that was fixed. Thank you very much.
