Change $HOME to $(HOME) or $$HOME
$(var) is the syntax for referring to make variables (or $x for single
letter or symbol variables). The variable is expanded by make before
passing it to the shell. make interprets $HOME as $(H)OME, and since $H
has no value, the result is "OME". You don't have to explicitly set
$(HOME) in your makefile. make inherits some variables from the
environment, $(HOME) is one of these.
"$$" escapes the '$' and prevents make from expanding the variable. make
passes a single '$' to the shell. So "$$HOME" becomes "$HOME". The shell
then expands the variable.
Cheers,
John
