jderobot package: gazebo error when try to run plugins

[lr-morales]

Hello all,

I have done a update to the current version of the jderobot (13-nov-2015) packages from the previous one (installed at 9-nov-2015) and after copying the models and world as described at the Advanced drone programming course , when running gzserver I got this output:

After checking some possibilities, I found that the dynamic libraries named in the output didn't have execution permissions. Running a chmod ugo+x over those plugins solved the issue, but gazebo should be able to run those when doing a fresh jderobot package install.

Could someone confirm if this is a general issue?

This system is a fresh xubuntu 14.04.3 (LTS) installation.

Hi @lr-morales,

which package did you install? and which architecture are you working on? I tried both packages in Ubuntu 14.04 32-64bits and they work fine.
Also, can you check please if those plugins are in the correct directory (/usr/local/share/jderobot/gazebo/plugins/)?
You should source the gazebo-setup.sh before start gazebo too.

Regards!

Hello,

I installed both jderobot-core and jderobot-deps and I'm using an x64
architecture for this.
The plugins are in the correct directory (I had to find them to perform the
chmod, but re-checked to be sure) and gazebo-setup.sh is sourced correctly.

Regards.

Ok I will wait for someone to report the same problem, cause @almartinflorido tested both packages too and it worked too.

Thanks for the report!

Installed from sources and permisions are 644

cmake automatically set 755 permisions for executables, but i dont known for libraries.

By the way, check if these libraries are installed like files or programs (related to issue #207)

Hi all,

I didn't had any problems with the installation or gazebo. I think that @lr-morales and @varhub uninstall a previous version of JdeRobot and after install the new version, right?.

My configuration is a x64 bits with Ubuntu 14.04 without previous versions of JdeRobot.

My error seems to be due outsource build
[Err] [Plugin.hh:153] Failed to load plugin /usr/local/share/jderobot/gazebo/plugins/quadrotor/libquadrotorplugin.so: libcolorspacesmm.so:
Because libcolorspacesmm.so was not been installed.

By the way, I checked my development chroot, whose do not complain about -x permission.

varribas@Ubuntu14lts:/home/datos/chroot/Hosted$ find JdeRobot5-git/usr/local/ -path '*gazebo/plugins/*' -name '*.so' -ls

So libraries do not requires exec permission nor gazebo has been updated and now requires it*.

Both have same Gazebo version gazebo5 5.1.0-1~trusty

@lr-morales , check if .so directories are listed into plugin path (export -p | grep GAZEBO).
What version have you got of gazebo?

[lr-morales]

Hello there,
I have repeated the installation process (following again the instructions from the drone course) in a new laptop and it seems to work correctly now. The only difference between both installations (excluding the laptop) is that in the first case I uptated from the previous version.

gazebo version is now 5.1.0
the export -p | grep GAZEBO contains the plugin directories inside the correct variable.

Thanks for your help, and if I notice more differences or possible causes, I'll post them here.
