[xemacs-hg @ 2004-08-21 17:05:49 by michaels] 2004-08-15 Jan Rychter <jwr@xemacs.org> * window-xemacs.el (really-set-window-configuration): deal gracefully with the case when the buffer previously saved in the configuration (and that we want to switch to) has been killed. Switch to the next buffer on the buffer-list in that case.

7 dnl There are several things we care about here. First, we need to find
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
8 dnl out how we create an executable that has its symbols exported, so
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
9 dnl that dynamically loaded modules have access to the internal XEmacs
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs

diff changeset
10 dnl symbols. This is stored in ``ld_dynamic_link_flags'' and is used
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
11 dnl in the main Makefile.
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
12 dnl Next, we need to know how we compile actual shared libraries, and
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
13 dnl the objects in them. For these purposes, we need to determine the
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
14 dnl C compiler flags used to produce shared objects (``dll_cflags''),
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
15 dnl what linker to use to create the final shared object that will be
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
16 dnl loaded (``dll_ld'') and the flags to pass to that linker
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
17 dnl (``dll_ldflags''). This information is used by ellcc to build up
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
18 dnl the command line when compiling modules. We build up two other commands
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
19 dnl for extremely weird systems where special things need to be done.
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
20 dnl The first is ``dll_ldo'', which is the flag used to specify the output
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
21 dnl file name, and the second is ``dll_post'' which is inserted after the
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
22 dnl list of objects.
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
23 dnl After all of this, we should be able to:
aabb7f5b1c81 Import from CVS: tag r21-2-9

diff changeset
24 dnl $(CC) $(CFLAGS) $(dll_cflags) -c module.c
aabb7f5b1c81 Import from CVS: tag r21-2-9

25 dnl to produce a single shared object
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
26 dnl And then:
aabb7f5b1c81 Import from CVS: tag r21-2-9
cvs
parents: 265
diff changeset
27 dnl $(dll_ld) $(dll_ldflags) $(dll_ldo) module.ell module.o $(dll_post)
aabb7f5b1c81 Import from CVS: tag r21-2-9
