Problems intalling YARP ubuntu 14.04 (Trusty)

[RaulFdzbis]

Hi all!

Right now im working in a clean computer with ubuntu 14.04. This means that i have to reinstall all the beautiful repos we have in roboticslab :D.

I open this issue because following the YARP installation guide, i had to solve some issues. Maybe i did something wrong, or maybe the guide needs to be updated.

In addition to the steps in the installation guide. I had to do the following steps:

• Install eigen3, as simple as:

sudo apt-get install libeigen3-dev

• Turn off CREATE_GUISS flag. When i tried to run cmake, an error related with Qt5 and that module was presented. The reason of this error was because CREATE_GUISS depends on Qt5 and Qt5 is disable in our installation. The solution was just to desactivate that module. The cmake command i used, was something like this.

cmake .. -DCREATE_LIB_MATH=ON -DCREATE_GUIS=ON -DCREATE_OPTIONAL_CARRIERS=ON -DENABLE_yarpcar_mjpeg_carrier=ON -DYARP_USE_QT5=OFF -DCREATE_GUIS=OFF # YARP_USE_QT5 can induce errors as of 02/2016

YARP underwent some noticeable changes in its latest releases, one of such is having dropped default GSL linkage in favour of Eigen (see description of commit asrob-uc3m/robotDevastation@0fcd210). Apart from that, carrier option names had their suffix trimmed (e.g. ENABLE_yarpcar_mjpeg_carrier has been replaced by ENABLE_yarpcar_mjpeg).

I think it's safe to include: sudo apt-get install libeigen3-dev

Regarding GUIs, the idea is to activate GUIs but deactivate QT5 to force QT4. Could you copy+paste the error log?

PS: Maybe a Ubuntu 14.04 section would be reasonable.

Sure!

I'm checking my install on Ubuntu 14.04.03 Trusty and I'm actually using Qt5. In fact, I haven't updated YARP very recently, but I can't even find YARP_USE_QT5. So I'd just go on considering YARP+Qt5 is stable enough. Actions to be taken (in a new branch, for trying it out):

• Remove -DYARP_USE_QT5=OFF from our install guides.
• Include all required packages for Qt5. I may be wrong, but I recall there there a quite few. We can comment on them through this thread as you're the one with the clean machine. :smile:

Finally get this thing working thanks to @jgvictores.

What i had to do was to install the needed package as explained in the Yarp homepage. This means:

sudo apt-get install qtbase5-dev qtdeclarative5-dev qtmultimedia5-dev \
  qml-module-qtquick2 qml-module-qtquick-window2 \
  qml-module-qtmultimedia qml-module-qtquick-dialogs \
  qml-module-qtquick-controls libqt5svg5

Note: In my case some of the packages were not found.

I also have had installed Qtcreator app from the official web page. However i dont think this had any influence.

Everything pretty decent as of e83d03f4a59e88009b0ce40d6c8e373f83c8c579, closing issue!
