1 dnl aclocal.m4 --- Dynamically linked library support for XEmacs

2 dnl Copyright (C) 1998, 1999 J. Kean Johnston.
|
|
|
3 dnl Author: J. Kean Johnston <jkj@sco.com>, based on work in libtool.
|
|
|
4 dnl This file is part of XEmacs.
|
|
|
5
|
|
|
6 dnl
|
|
|
7 dnl There are several things we care about here. First, we need to find
|
|
|
8 dnl out how we create an executable that has its symbols exported, so
|
|
|
9 dnl that dynamically loaded modules have access to the internal XEmacs
|
|
|
10 dnl symbols. This is stored in ``ld_dynamic_link_flags'' and is used
|
|
|
11 dnl in the main Makefile.
|
|
|
12 dnl Next, we need to know how we compile actual shared libraries, and
|
|
|
13 dnl the objects in them. For these purposes, we need to determine the
|
|
|
14 dnl C compiler flags used to produce shared objects (``dll_cflags''),
|
|
|
15 dnl what linker to use to create the final shared object that will be
|
|
|
16 dnl loaded (``dll_ld'') and the flags to pass to that linker
|
|
|
17 dnl (``dll_ldflags''). This information is used by ellcc to build up
|
|
|
18 dnl the command line when compiling modules. We build up two other commands
|
|
|
19 dnl for extremely weird systems where special things need to be done.
|
|
|
20 dnl The first is ``dll_ldo'', which is the flag used to specify the output
|
|
|
21 dnl file name, and the second is ``dll_post'' which is inserted after the
|
|
|
22 dnl list of objects.
|
|
|
23 dnl After all of this, we should be able to:
|
|
|
24 dnl $(CC) $(CFLAGS) $(dll_cflags) -c module.c
|
|
|
25 dnl to produce a single shared object
|
|
|
26 dnl And then:
|
|
|
27 dnl $(dll_ld) $(dll_ldflags) $(dll_ldo) module.ell module.o $(dll_post)
|
|
|
28 dnl to create the loadable shared library.
|
|
|
29 dnl
|
|
|
30 dnl NOTE: In the code below, where I have modified things to work with
|
|
|
31 dnl XEmacs, we use $canonical instead of libtool's $host, and we use
|
|
|
32 dnl $internal_configuration instead of $host_alias. To make typing
|
|
|
33 dnl shorter we assign these to $xehost and $xealias

|
|
|
206 dnl Now comes the LD trickery. We do things differently to libtool here.
|
|
|
207 dnl I believe that libtool is incorrect in trying to drive the linker
|
|
|
208 dnl directly. This can cause considerable problems if the module you are
|
|
|
209 dnl compiling has C++ or other static initializers. If we use ld directly,
|
|
442
|
210 dnl we don't end up with the crt stuff being linked in, and we don't end up
|
|
388
|
211 dnl with any .init or .fini sections (or the moral equivalent thereof).
|
|
442
|
212 dnl gcc takes great care to do this properly when invoked in -shared
|
|
|
213 dnl mode, and we really do want this behavior. Perhaps the libtool folks
|
|
388
|
214 dnl are not aware that any SVR4 based dynamic loader will automatically
|
|
|
215 dnl execute code in the .init section before dlopen() returns. This is
|
|
442
|
216 dnl vital, as the module may have been compiled to rely on that behavior.
|
|
388
|
217 dnl
|
|
|
218 dnl So, having said all of that, we diverge from libtool significantly
|
|
|
219 dnl here. We want to try and use the C compiler as much as possible. Only
|
|
2079
|
220 dnl if the C compiler itself cannot create shared libraries do we try to
|
|
388
|
221 dnl find the linker.
|
|
|
222 dnl
|
|
|
223 dnl The other advantage to my scheme is that it removes the dependancy
|
|
|
224 dnl on a given compiler version remaining static with relation to the
|
|
|
225 dnl version of XEmacs. With the libtool way, it picks up the linker that
|
|
|
226 dnl gcc uses, which can be the internal collect2 that comes with gcc.
|
|
|
227 dnl If the user ever changes their compiler version, the paths will no
|
|
|
228 dnl longer be correct, and ellcc will break. This is clearly unacceptable.
|
|
442
|
229 dnl By using the compiler driver on the path, we don't have this problem.
|
|
388
|
230 dnl If that is not clear, consider that gcc -print-prog-name=ld can
|
|
|
231 dnl produce something along the lines of:
|
|
|
232 dnl /usr/local/lib/gcc-lib/OS-NAME/GCC-VERSION/ld
|
|
|
233 dnl If you ever change GCC versions, then that path no longer exists.
|
|
|
234 dnl
|
|
|
235 dnl So, we change the check order here. We first check to see if we are
|
|
|
236 dnl using GCC, and if so, we see if -shared works. If it does, great.
|
|
|
237 dnl If we are not using gcc, but the system C compiler can produce
|
|
|
238 dnl shared objects, we try that. Only if all of that fails do we revert
|
|
|
239 dnl back to the libtool ld trickery.
|
|
|
240 dnl
|
|
442
|
241 dnl We don't do ANY of this if we can't produce shared objects.
