Ralf> "make clean" seems to be broken. AFAICT, in multilib'ed subdirs it
Ralf> recurses on mostly-clean first and then once again on "clean"
The dependencies are as follows
| mostlyclean-am: mostlyclean-multi mostlyclean-other
| mostlyclean: mostlyclean-am
|
| clean-am: clean-multi clean-other mostlyclean-am
| clean: clean-am
So calling `make clean' will cause both `make clean-multi' and
`make mostlyclean-multi' to run. Obviously this is not wanted
because clean-multi has already done the job of mostlyclean-multi.
Moving the *-multi rules as dependencies of the main rules seems
to do the trick.
| mostlyclean-am: mostlyclean-other
| mostlyclean: mostlyclean-am mostlyclean-multi
|
| clean-am: clean-other mostlyclean-am
| clean: clean-am clean-multi
I think this sheds some light on Akim's original question.
Perhaps that's what the original code tried to do, putting
dependencies on -recursive rules instead (right now I don't see
what that would change: adding dependencies to foo-recursive is
just like to foo, except the latter will also work when
subdirectories are not used; but I may be missing something).
Here is an updated patch. Adding your `mycc' to the test case
also revealed the need for symlink-tree in non-VPATH builds.
2003-07-21 Alexandre Duret-Lutz <address@hidden>
* automake.in (handle_multilib): Register all-multi.

from Ralf Corsepius (see GCC's PR 11526).

(mostlyclean-am, clean-am, distclean-am, maintainer-clean-am): Replace
by ...

+# Things are complicated because 6 separate cases must be handled:
+# 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
+#
+# srcdir=. is special. It must handle make programs that don't handle VPATH.
+# To implement this, a symlink tree is built for each library and for each

+# The build tree is layed out as

+# ./

+#
+# The nice feature about this arrangement is that inter-library references
+# in the build tree work without having to care where you are. Note that
+# inter-library references also work in the source tree because symlink trees
+# are built when srcdir=.
+#

+# tree. It exists to handle the case of configuring in the source tree:
+# ${srcdir} is not constant.
+# ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).
+#
+# Makefile variables:
+# MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
+# (FIXME: note that this is different than ${with_multisrctop}. Check out.).
