Regression: Cannot compile VirtualBox 5.2.4 on Ubuntu 16.04, Qt5 not found

[core-it-admin]

Even with the qt5 package installed on Ubuntu 16.04, the VirtualBox 5.2.4 configure script does not find Qt5. This is a regression since VirtualBox 5.1.

I ran into the same problem.

I found the answer at ​http://matshao.com/2019/04/11/VirtualBox-Exploitation-1

The problem is that the config file has the following lines:

QT5DIR_PKGCONFIG=1
QT5MAJ=5
QT5MIN=6

This states that the minimum qt version that config will allow is 5.6, but the error does not tell you that, and the virtualbox web site does not tell you that.

If you change "QT5MIN=6" in the config file to "QT5MIN=4" or what ever qt5.<version> you have, the config will work. But You could have other problems, as it would be better to upgrade qt5 to 5.6 or above.

It's too bad that virtualbox does not tell us that the minimum qt version is 5.6

Furthermore

https://www.virtualbox.org/wiki/Linux%20build%20instructions
states
"Prerequisites
You need: "
"Qt 4.x.y (with x >= 4, including the OpenGL part, required for VBox version > 3.0)"

But I see nowhere in the code where Virtualbox will build with qt4. What I see is that "--build-headless" and "WITH_QT5=0" is one in the same.

It's too bad that this has still not been fixed.
