Note the semicolon before the final close-paren.

What you wanted was:

gmake -C controlBoard;  gmake -C displayBoard;  gmake -C 
serialOptionBoard;

The lack of the semicolons causes the shell to interpret all the tokens 
following "controlBoard" as arguments to the first gmake command. The 
second "-C" argument to gmake causes it to try to descend into the  
controlBoard/displayBoard subdirectory, which doesn't exist, hence the 
error messages:
> gmake: Entering an unknown directory
> gmake: Leaving an unknown directory
