The following error occurs:

ubuntu@computer01:~/Ziya/argos3-examples/experiments$ argos3 -c synchronization.argos
[FATAL] Can't load library "/usr/lib/argos3/libargos3plugin_simulator_dynamics3d.so" even after trying to add extensions for shared library (so) and module library (so):

CMagnetEquippedEntity is not in current argos release (beta 50), but it is on github (I did not try the github version).

Hi @eliseofe, to diagnose the issue I need some more information. Can you let me know the following?

  1. You have installed ARGoS from the DEB package, correct?
  2. Can you give me the output of uname -a and lsb_release -a
  3. Have you previously installed an older version of ARGoS on this computer?
  4. Can you give me the output of ls -al /usr/local/lib/argos3/ and ls -al /usr/lib/argos3/
  5. Is that the whole output from running argos3 -c synchronization.argos or are you just showing the relevant sample of the output?

I tried reproducing your problem on Ubuntu 16.04 and Mac OS Sierra, but everything seems to be working correctly.

If you install beta50 and run argos3 -q all, what's the output?

I suspect that you have ARGoS installed twice in the system.

The output of the commands mentioned by @allsey87 and argos3 -q all will tell us what's going on :-) We'll wait for an answer.

@eliseofe What I have is the same as you guys. @allsey87 might have more files, but they work for me. I'm looking into it.

I checked the files and there seems to be nothing off. Please try these commands and show me the output in text form (no screenshots, I need to be able to copy-paste):

  1. ls -l /usr/lib/argos3
  2. ldd /usr/lib/argos3/libargos3plugin_simulator_dynamics3d.so

What version of Ubuntu are you using? 32 or 64 bits?

Thanks @ARArun, I think I have a solution. I'll make a new beta50 in a few minutes.

Different versions of ld have different linking behaviors, and the order in which libraries are linked may vary. In my tests, the order was such that this issue did not appear. On some systems, the issue causes a crash. The solution was to fix a CMake script that was added recently to make the library dependencies explicit.
