Support for building as a shared library, based on patches from
Alan Modra <alan@spri.levels.unisa.edu.au>: * configure.in: Add AC_ARG_ENABLE for shared and commonbfdlib. New substitutions: ALLLIBS, PICFLAG, SHLIB, SHLIB_CC, SHLIB_CFLAGS, COMMON_SHLIB, PICLIST, SHLINK. * configure: Rebuild. * configure.host: If --enable-shared, adjust shared library stuff based on the host. If the host is SunOS, and the linker supports -rpath, set HLDFLAGS to use it. * Makefile.in (ALLLIBS): New variable. (PICFLAG, SHLIB, SHLIB_CC, SHLIB_CFLAGS): New variables. (COMMON_SHLIB, SHLINK): New variables. (.c.o): If PICFLAG is set, compile twice, once PIC, once normal. (STAGESTUFF): Remove variable. (all): Depend upon $(ALLLIBS) and @PICLIST@ rather than $(TARGETLIB). (stamp-ofiles): New target, like old ofiles target, but build using a temporary file and move-if-change, and touch stamp-ofiles when done. (ofiles): Just depend upon stamp-ofiles. (stamp-piclist, piclist): New targets. ($(SHLIB), $(SHLINK)): New targets. (targets.o, archures.o): Build twice if PICFLAG is set. (do_mostlyclean): Remove pic/*.o. (do_clean): Remove stamp-ofiles, $(SHLIB), $(SHLINK), piclist, and stamp-piclist. (do_distclean): Remove pic and stamp-picdir. (install): Install shared libraries.

Support for building as a shared library, based on patches from
|
||||
Alan Modra <alan@spri.levels.unisa.edu.au>:
|
||||
* configure.in: Add AC_ARG_ENABLE for shared and commonbfdlib.
|
||||
New substitutions: ALLLIBS, PICFLAG, SHLIB, SHLIB_CC,
|
||||
SHLIB_CFLAGS, COMMON_SHLIB, PICLIST, SHLINK.
|
||||
* configure: Rebuild.
|
||||
* configure.host: If --enable-shared, adjust shared library stuff
|
||||
based on the host. If the host is SunOS, and the linker supports
|
||||
-rpath, set HLDFLAGS to use it.
|
||||
* Makefile.in (ALLLIBS): New variable.
|
||||
(PICFLAG, SHLIB, SHLIB_CC, SHLIB_CFLAGS): New variables.
|
||||
(COMMON_SHLIB, SHLINK): New variables.
|
||||
(.c.o): If PICFLAG is set, compile twice, once PIC, once normal.
|
||||
(STAGESTUFF): Remove variable.
|
||||
(all): Depend upon $(ALLLIBS) and @PICLIST@ rather than
|
||||
$(TARGETLIB).
|
||||
(stamp-ofiles): New target, like old ofiles target, but build
|
||||
using a temporary file and move-if-change, and touch stamp-ofiles
|
||||
when done.
|
||||
(ofiles): Just depend upon stamp-ofiles.
|
||||
(stamp-piclist, piclist): New targets.
|
||||
($(SHLIB), $(SHLINK)): New targets.
|
||||
(targets.o, archures.o): Build twice if PICFLAG is set.
|
||||
(do_mostlyclean): Remove pic/*.o.
|
||||
(do_clean): Remove stamp-ofiles, $(SHLIB), $(SHLINK), piclist, and
|
||||
stamp-piclist.
|
||||
(do_distclean): Remove pic and stamp-picdir.
|
||||
(install): Install shared libraries.
|
||||
($(OFILES)): Depend upon stamp-picdir.
|
||||
(stamp-picdir): New target.
|
||||
|
||||
* libcoff-in.h: Add comment reminding people that libcoff.h is a
|
||||
generated file.
|
||||
* libcoff.h: Rebuild.
