Installing Gazebo from source on Ubuntu 14.04 : Unable to locate package libqwt-qt5-dev

I am trying to install Gazebo from source on Ubuntu 14.04 (would wish to be on 16.04 but I unfortunately need another library for my project which is only supported on 14.04...).

So I followed the procedure found here :

and while installing the dependencies, at step 3 "Install prerequisites", got this message error :

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libqwt-qt5-dev

I understand I don't have libqwt-qt5-dev, but when trying to install it :

sudo apt-get install libqwt-qt5-dev

I get :

E: Unable to locate package libqwt-qt5-dev

Not sure, but looking at this, it seems that the library has no package for 14.04 :

So... my question would be what is the most recent version of Gazebo to use in 14.04 and how to install it from source? Even when I change the Gazebo version in the tutorial, I get the same procedure (or maybe I do not see the difference).

Thanks in advance, any help is really appreciated.

Finally, I found out what was my problem. In this Gazebo tutorial (this links to the Gazebo 7 version of the tutorial as Gazebo 7 is the last version available on Ubuntu 14.04 Trusty), the first steps are the following :

wget -O /tmp/
ROS_DISTRO=dummy . /tmp/
sudo apt-get install $(sed 's:\\ ::g' <<< $GAZEBO_BASE_DEPENDENCIES) $(sed 's:\\ ::g' <<< $BASE_DEPENDENCIES)

So I looked at the file /tmp/ in gedit and found out that I need to specify GAZEBO_MAJOR_VERSION=7 prior to running the script so that it does not look for libqwt-qt5-dev. So here is what I suggest to those trying to build Gazebo from source on Ubuntu 14.04. When installing the dependencies at the begining of the procedure in the tutorial, do the following instead :

wget -O /tmp/
sudo apt-get install $(sed 's:\\ ::g' <<< $GAZEBO_BASE_DEPENDENCIES) $(sed 's:\\ ::g' <<< $BASE_DEPENDENCIES)

Just added GAZEBO_MAJOR_VERSION=7 DISTRO=trusty to the second command line.

Then, building Gazebo from source (using gazebo7 branch) worked fine.

We dropped Trusty in Gazebo 8. The most recent version that you should be able to install from source or debs in Ubuntu Trusty is Gazebo 7 (branch gazebo7 on the repository). Make sure to remove your build directory before recompiling just in case.

Thanks for answering. I agree about Gazebo 7 being the last version for Trusty. Then where can I find the installation procedure for the dependencies of gazebo (not having cloned gazebo yet) so that it does not asks for libqwt-qt5-dev? Because these are deb packages and I don't know how to specify a version if that is possible. I suppose I can install gazebo 7 without that library somehow if. Right?

"Because these are deb packages and I don't know how to specify a version if that is possible." By that I meant : is there a different prompt command than wget -O /tmp/ ROS_DISTRO=dummy . /tmp/ sudo apt-get install $(sed 's:\\ ::g' <<< $BASE_DEPENDENCIES) $(sed 's:\\ ::g' <<< $GAZEBO_BASE_DEPENDENCIES) That last line is where I am stucked. Thanks again for your help

The gazebo7 branch on will not depend on libqwt-qt5-dev. If you want to install gazebo from source, you'll need to clone the repository and update to the gazebo7 branch. Then try cmake, make, make install.

if you're building from source and don't mind using gazebo without the plotting tool then you can try modifying gazebo to make qwt an optional dependency. Changes in this commit should help:

Thanks for your help, The link on bitbucket does not seem to work when I try to load it. However, I finally found a way to build gazebo on my own and I made a new answer to explain what I did. If you have any comment on that answer, feel free to do so. Thanks again!
