Hi all
This is a proposed patch to use partial linking with Automake-1.9.6
This mail contains the patch only, the discussion is on address@hidden
A copy of the patch is also available for download at :
http://sourceforge.net/project/showfiles.php?group_id=160169
I will provide later versions (with fixes based on your kind comments)
there.
There are new tests, but no documentation yet.
The plan is to write the doc based on comments in the discussion thread,
so it will come separately.
The test aclocal7.test has spurious failures on my machine, both before
(Automake-1.9.6) and after the patch.
I did not investigate yet. Other tests passed as expected; a few were
skipped.
A couple of warnings:
1) I tried my best with automake.in, but I lack both perl skills
(this is my **first** perl code, I don't know what I wrote, just
"monkey'ed" similar code and tweaked)
and knowledge of automake internals, so this code needs review.
2) Also, I can't guarantee that tabs characters are preserved properly here,
starting with my own mail reader, so the code send is just to facilitate
code review and comments. This can affect Makefiles, so in doubt,
download the real file.
Cheers,
Marc Alff.
