Hello Vladimir, thank you for the prompt answer. I implemented the patch, but now I get a different error, this time from the linker. The output is attached. Best, Diego

Hello, Diego,
The problem is with the new lst container initialisation. I am attaching a patch to this code. With this patch I am able to compile the code with your command
g++ -std=c++11 GPLs.cpp -o GPLs.out -w -lcln -lginac
on my Debian box.
