depended on because it is not used. Work around it for now by checking that the target is actually non-empty explicitly. This is still simpler than the original code. After the branch, this will be reordered so that it only gets set to non-default values when it will be used.

#
|
|
# The following variables may be set by the package Makefile and
|
|
# specify how extraction happens:
|
|
#
|
|
# EXTRACT_DIR
|
|
# The directory into which the files are extracted.
|
|
#
|
|
# Default value: ${WRKDIR}
|
|
#
|
|
# EXTRACT_CMD is a shell command list that extracts the contents of
|
|
# an archive named by the variable ${DOWNLOADED_DISTFILE} to the
|
|
# current working directory. The default is ${EXTRACT_CMD_DEFAULT}.
|
|
#
|
|
# EXTRACT_OPTS is a list of options to pass to the "extract" script
|
|
# when using EXTRACT_CMD_DEFAULT. See the comments at the head of
|
|
# the "extract" script for a definitive list of the available
|
|
# options. The default list is empty.
|
|
#
|
|
# EXTRACT_USING specifies the tool used to extract tar/ustar-format
|
|
# archives when using EXTRACT_CMD_DEFAULT. The possible values are
|
|
# "gtar", "nbtar", and "pax". By default, we use the "nbtar" tool
|
|
# (pkgsrc's pax-as-tar).
|
|
#
|
|
# EXTRACT_ELEMENTS is a list of files within the distfile to extract
|
|
# when using EXTRACT_CMD_DEFAULT. By default, this is empty, which
|
|
# causes all files within the archive to be extracted.
|
|
#
|
|
# The following are read-only variables that may be used within a package
|
|
# Makefile:
|
|
#
|
|
# DOWNLOADED_DISTFILE represents the path to the distfile that is
|
|
# currently being extracted, and may be used in custom EXTRACT_CMD
|
|
# overrides, e.g.
|
|
#
|
|
# EXTRACT_CMD= ${TAIL} +25 ${DOWNLOADED_DISTFILE} > foo.pl
|
|
#
|
|
# EXTRACT_CMD_DEFAULT uses the "extract" script to unpack archives. The
|
|
# precise manner in which extraction occurs may be tweaked by setting
|
|
# EXTRACT_OPTS, EXTRACT_USING and EXTRACT_ELEMENTS.
