I've followed the instructions on how to compile the sample plugins on a Linux machine (http://wiki.anvelsim.com/2/index.php/Compiling_ANVEL_Sample_Projects), both in debug and release mode.
but after compiling, there are no new .so files in the /usr/ANVEL/bin/x64/Release/Plugins or /usr/ANVEL/bin/x64/Debug/Plugins folders
Did you invoke the commands with sudo? The resulting *.so files in 2.0 are set up to go to /usr/ANVEL directory, which needs elevated permissions for writing. Did the compilation process generate any errors or warnings?
