| 37 | # The targets listed in the the FETCHES target list have the following attributes:
|
|---|
| 38 | # SOURCES
|
|---|
| 39 | # INST
|
|---|
| 40 | # FETCHTOOL
|
|---|
| 41 | # FETCHFLAGS
|
|---|
| 42 | # FETCHDIR
|
|---|
| 43 | # UNPACKTOOL
|
|---|
| 44 | # UNPACKFLAGS
|
|---|
| 45 | #
|
|---|
| 46 | # As usual the target name is an alias for 'creating' the target. Other
|
|---|
| 47 | # aliases are:
|
|---|
| 48 | # pass_fetches
|
|---|
| 49 | # fetch
|
|---|
| 50 | # unfetch
|
|---|
| 51 | # download
|

| 52 | # unpack
|
|---|
| 53 | #
|
|---|
| 54 | # @remark
|
|---|
| 55 | #
|
|---|
| 56 | # This is a little bit complex because we must guarantee that if a source file
|
|---|
| 57 | # changes only sligtly we must refetch it and to a proper unpacking of it. It
|
|---|
| 58 | # is also a desire that fetched archives and unpacked files can be deleted to
|
|---|
| 59 | # save space.
|
|---|
| 60 | #
|
|---|
| 61 | # Thus, we must be able to cleanup what we've unpacked should any of the
|
|---|
| 62 | # sources be removed. We do this by maintaining a file listing the files
|
|---|
| 63 | # and directories that was unpacked. This operation is named 'unfetch'.
|
|---|
| 64 | #
|
|---|
| 65 | # We make use of the SIZE and MD5 attributes for each of the sources to
|
|---|
| 66 | # create a digest that is stored in the primary target file. Subsequent
|
|---|
| 67 | # runswill compare their digest with it to decide if a refetch is required.
|
|---|
| 68 | # When a refetch is found necessary, an 'unfetch' is performed first to
|
|---|
| 69 | # clean out old files and directores. Note even changes in source order
|
|---|
| 70 | # will cause a refetch due to the way the digest is constructed and
|
|---|
| 71 | # evaluated.
|
|---|
| 72 | #
|
|---|
| 73 | # By not depending directly on the archives (nor on any unpacked files)
|
|---|
| 74 | # but on a goal made up from the archive name, size and md5, we allow
|
|---|
| 75 | # the user to delete the archives. Naturally, this means we'll have to
|
|---|
| 76 | # check and fetch missing archives before attempting to unpack them.
|
|---|

|
|---|
| 80 | # This feature will *NOT* work correctly with vanilla GNU make becuase
|
