OK, I think it works.
1:st part with halcompile gearblokcer.comp no errors
2:nd part with halcompile --compile gearblocker.comp there is a list of errors See enclosed compile.txt
Is all OK or not?

No, there are typos and errors in the file.
Firstly, I have copy-and-paste errors, the cases should be 1, 2, 4, 8, 16, default
"case else" is wrong. it should be "default:" I have been coding too much Visual Basic recently, and that is the VB equivalent.
Also, I have got some of the internal names of the pins mixed up (should be gear_min_speed() )
I also spotted an off-by-one error in the gear numbering (the HAL pins always start at zero, so we need to number gears from zero)

Andy, a very nice piece of code. You are better than me! I refuse to do anything in Visual Basic!

Andy's left some typos so you can learn more about C coding 
Change Line 47 to:
The error tells you exactly the problem
gearblocker.comp:47:23: error: ‘spindle_speed_’ undeclared (first use in this function)
spindle_speed_’ should be spindle_speed_in’
Change Line 47 to:
motor_speed_out = spindle_speed_in * gear_ratio(gear);The error tells you exactly the problem
gearblocker.comp:47:23: error: ‘spindle_speed_’ undeclared (first use in this function)
spindle_speed_’ should be spindle_speed_in’

I got a .ko file now so I assume all is OK even with above warning?

I have added following lines to HAL
So how to do with following lines in COMP
# gearbox input signals
# gearbox Hi/Lo
net gearblocker.0.high-gear <= hm2_7i76e.0.7i76.0.0.input-15
# gearbox A - B - C - D - E
net gearblocker.0.gear-A <= hm2_7i76e.0.7i76.0.0.input-10
net gearblocker.0.gear-B <= hm2_7i76e.0.7i76.0.0.input-11
net gearblocker.0.gear-C <= hm2_7i76e.0.7i76.0.0.input-12
net gearblocker.0.gear-D <= hm2_7i76e.0.7i76.0.0.input-13
net gearblocker.0.gear-E <= hm2_7i76e.0.7i76.0.0.input-14loadrt gearblocker
addf gearblocker.0 servo-threadSo how to do with following lines in COMP
component gearblocker;
pin in bit spindle-enable-in;
pin out bit spindle-enable-out;
pin in float spindle-speed-in;
pin out float motor-speed-out;
pin in float gear.#.min-speed[10];
pin in float gear.#.max-speed[10];
pin in float gear.#.ratio[10];Please Log in or Create an account to join the conversation.

Yeh, you've done the right thing. It was just C politely telling you there was a variable that had not been used.
Warnings are basically telling you there is a problem that might be a problem but its not a fatal error so it will compile OK. Its best to eliminate them though as sometimes they can bite you.
