I am getting the following error for some of my projects. I don't know why. It was OK before.

The error says:

Code: Select all

Can't load library "build/controllers/epuck_test1/libepuck_test1.so" even after trying to add extensions for shared library (so) and module library (so):

Either you're running ARGoS from the wrong directory, or the library does not exist. Try with

Code: Select all

$ ls build/controllers/epuck_test1/libepuck_test1.so

Does that say that the library exists?

Yes, the library exists, and I am running ARGoS from the same directory I always do. All other samples run with no problem.
If I copy the *.so file to

Code: Select all

/usr/local/lib/argos3/build/controllers/epuck_test1/

, the sample runs, but nothing happens in the simulator and all the robots are frozen.

You shouldn't copy your controller files in /usr. ARGoS looks for those files in multiple directories and reports where it did. Probably it's something in your code. Zip the entire project directory you have (delete the build directory) and upload it here, I'll have a look.

I emailed the code.
