Re: [etherlab-users] ec_slave3.c

Hello,
As far as I know, you should not mex ec_slave3.c. Instead, you just need to update the (old) version of the file as was installed by Etherlab with a newer one. The file is automatically used during the build process in Simulink. 


See https://www.symbitron.eu/wiki/index.php?title=EtherLab_Installation 
, there's a small section on that.


Please report if this helps for you.

Best,

Gijs van Oort
