Re: HELP! Can I construct individial shell commands using a function

[Luke Shumaker]

The trick is to get the different commands on different lines.  Try
this:

define _ExecuteShcmdArray
$(foreach c,$1,@$($c)
)
endef

shellcmd1 = cd .. ; pwd
shellcmd2 = cd .. ; pwd

all:
        $(call _ExecuteShcmdArray,shellcmd1 shellcmd2)
