# MAKEOBJDIR A pathname for the directory where the targets
|
|
# are built. Note: MAKEOBJDIR is an *environment* variable
|
|
# and works properly only if set as an environment variable,
|

# not as a global or command line variable!

# E.g. use `env MAKEOBJDIR=temp-obj make'

# MAKEOBJDIRPREFIX Specifies somewhere other than /usr/obj to root the object
|
|
# tree. Note: MAKEOBJDIRPREFIX is an *environment* variable
|
|
# and works properly only if set as an environment variable,
|
|
# not as a global or command line variable!
