Error running basic examples

[Ons_snO]

Hello,

When I try to run any simulation from the examples provided through GitHub, I get this error:

Code: Select all

[FATAL] Can't load library "/usr/local/lib/argos3/libargos3plugin_simulator_epuck.so" even after trying to add extensions for shared library (so) and module library (so): /usr/local/lib/argos3/libargos3plugin_simulator_epuck.so: libQt5Core.so.5: cannot open shared object file: No such file or directory /usr/local/lib/argos3/libargos3plugin_simulator_epuck.so.so: /usr/local/lib/argos3/libargos3plugin_simulator_epuck.so.so: cannot open shared object file: No such file or directory /usr/local/lib/argos3/libargos3plugin_simulator_epuck.so.so: OK

Any idea how to solve this, please?

Thank you in advance!

Did you install ARGoS from source or from a package ? It looks like ARGOS can't find all its libraries. Does the <install prefix>/lib/argos3 contain the epuck library ?

Hi John,
Many thanks for your reply.
I have Argos libraries including the ones mentioned in the error message.

Code: Select all

libargos3core_simulator.so libargos3plugin_simulator_genericrobot.so libargos3plugin_simulator_dynamics2d.so libargos3plugin_simulator_media.so libargos3plugin_simulator_dynamics3d.so libargos3plugin_simulator_pointmass3d.so libargos3plugin_simulator_entities.so libargos3plugin_simulator_prototype.so libargos3plugin_simulator_epuck.so libargos3plugin_simulator_qtopengl.so libargos3plugin_simulator_eyebot.so libargos3plugin_simulator_spiri.so libargos3plugin_simulator_footbot.so

I have installed it from a package.

Many thanks

Do you have Qt installed ? It looks like libQt5Core.so is missing. What does "ldd /path/to/argos3/lib/libargos3plugin_simulator_epuck.so" show ?

Do you happen to have Anaconda installed? That is a common cause for errors like this. Please report the output of 'echo $LD_LIBRARY_PATH', it's gonna help us find spot the issue.

Many thanks for your answers. I fixed that issue, but now I have another one.

Code: Select all

[FATAL] Failed to initialize the visualization. Parse error in the <visualization> subtree. [FATAL] Error initializing QTOpenGL camera settings [FATAL] Error parsing attribute "idx" Attribute does not exist <ticpp.h@1791>

I have tried all the possible solutions I found online, but nothing helped.

Do you have any idea how to fix this please?

Appreciate your help!

We just updated ARGoS to beta57. The attribute 'idx' became 'index'. Check the output of 'argos3 -q qt-opengl' for details.
