I have downloaded the source code for OpenCPN V5 and unpacked it.
Now I need to download the dependencies.
I suspect the ones mentioned in the manual OpenCPN_buildwin-4.99a.7z not to be the correct ones, or are they ?
I have gone back to try testing your opencpn v4.2.1 filter version downloaded from the google drive. I cannot see to find the "IIR Filter" setting in opencpn.ini to change it from 9 to 0 for testing. What am I doing wrong?
-do I have to add it manually?
-if so, where, which section?
ConfigVersionString=Version 4.2.1 Build 2016-03-09 <-- Thought this was the right one
