Symbol "kilobot" not found

Postby AntonioC » Fri Jan 07, 2022 2:36 pm

When I try to run the command:

Code: Select all

argos3 -c src/examples/experiments/kilobot_blinky.argos
The following errors appear:

Code: Select all

[FATAL] Failed to initialize the space. [FATAL] Symbol "kilobot" not found.

You need to install the kilobot plugin with make install.
I made ARGoS.

I downloaded the folder from: https://github.com/ilpincy/argos3-kilobot
And I ran the following commands:

Code: Select all

mkdir build cd build cmake -DCMAKE_BUILD_TYPE=Release ../src make sudo make install

Maybe your installation is not correct. What's the output of the following commands:

Code: Select all

which argos3 ls /usr/local/lib/argos3 ls /usr/local/bin/argos3 ls /usr/lib/argos3 ls /usr/bin/argos3
I made ARGoS.

OK so the problem is due to the fact that ARGoS is installed in /usr/lib/argos3, but the kilobot plugin is installed in /usr/local/lib/argos3.

Two possible solutions:

Code: Select all

sudo mv /usr/local/lib/argos3 /usr/lib
or

Code: Select all

rm -rf /usr/local/lib/argos3 cd argos3-kilobot rm -rf build mkdir build cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr ../src make sudo make install
I made ARGoS.

Well, then copy the files over and remove them... :-)
I hope the point is clear: the files are in the wrong place.
I made ARGoS.

I logged in as root and ran the commands you wrote me. Now everything works. Thanks so much. :D
