Tom, the 'sudo strip -g libeo.so' on my computer prevents me to see info about this library in gdb, as explained before. How can I compile Eo in release mode?
Gustavo, this could be very useful. We need to check if it really can be done and if it is easy for the user. Is the eo_do_step supposed to execute the functions too? How does it wait for commands (your last line), I mean, is it inside the eo_do_step function? Eo uses va_list to store the parameters and we need to be careful with that.
