Slicer3d compilation on Ubuntu 20.04 lts

Chintha_Siva_Prasad · August 24, 2021, 10:28am

I am trying to build slicer by compiling the source code. When I am building it through cmake command it’s saying that it requires atleast 5.15.1.

But when I am using qt-default , it’s not installing the required version. And when tried to install latest version(6.x) through qt-online installer,it’s installing in a custom directory and while building slicer it’s using the older version.How can I resolve this issue? Is there a way to specify qt directory when I am compiling slicer? Or there is a optimal way to resolve this issue?

You can work around this by setting Slicer_REQUIRED_QT_VERSION CMake variable to 5.12.8. You can follow further discussion here:

Build on Ubuntu fails due to strict Qt version check

When following linux build instructions on Ubuntu 20.04, the [prerequisites that… are installed by the provided command](https://slicer.readthedocs.io/en/latest/developer_guide/build_instructions/linux.html#ubuntu-20-04-focal-fossa) are not sufficient to build Slicer: I got a CMake error message that minimum Qt-5.12.1 is required. Either the build instructions have to be updated so that it gets the required Qt version, or the Qt version check has to be relaxed.
