I'm attempting to follow this post

How to install Point Cloud Library v1.8 (pcl-1.8.0) on Ubuntu 16.04.2 [LTS] for C++?

However, I'm using Ubuntu 18.04 rather than 16.04.

If I do this command on 18.04:

sudo apt-get install qt-sdk

I get:

Unable to locate package qt-sdk

Per this link:

https://packages.ubuntu.com/search?keywords=qt

It seems that qt-sdk was a package for 14.04 and 16.04 but is no longer a package for Ubuntu 18.04. Can anybody suggest the 18.04 equivalent so I can continue with the PCL install in the above linked post?

The qt-sdk package included the development libraries for Qt4. You can install these in 18.04 using the following:

sudo apt install libqt4-dev

I should have researched this a bit more before I posted. Per this:

https://packages.ubuntu.com/xenial/qt-sdk

In 16.04 qt-sdk installed these:

build-essential
cmake
gdb
git-core
libphonon-dev
libqt4-dev
libqt4-opengl-dev
libqtwebkit-dev
qt4-designer
qt4-dev-tools
qt4-doc
qt4-doc-html
qt4-qmake
qtcreator
qtcreator-doc
subversion
libqt4-dbg
libqt4-webkit-dbg
libqt4-xmlpatterns-dbg

So, pretty much everything Qt 4. I'm not sure if, with PCL 1.8.x and Ubuntu 18.04, I should stick with Qt 4 or move to Qt 5, but in any case that is a different post entirely.
