Bug ID: 61097
Summary: Solaris linker change broke --disabled-shared support
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org
Reporter: gnugcc at marino dot st
Regarding the patch "[build, libgcc] Ensure libgcc_s unwinder is always used on
64-bit Solaris 10+/x86 (PR target/59788)"
http://gcc.gnu.org/ml/gcc-patches/2014-01/msg01088.html
This change seems to have broken the --disabled-shared support for the native
solaris linker.
I am seeing this error on GCC 4.9.0 with that option set.
> gmake[5]: Entering directory
> /mech/pkgsrc-work/lang/gcc-aux/work/build/x86_64-aux-solaris2.11/32/libgcc'
> # If this is the top-level multilib, build all the other gmake[5]: *** No
> rule to make target 'libgcc-std.ver', needed by 'libgcc-unwind.map'.
> Stop.
It is caused by libgcc/config/t-slibgcc-sld excerpt:
> # Linker mapfile to enforce direct binding to libgcc_s unwinder
> # (PR target/59788).
> libgcc-unwind.map: libgcc-std.ver
> @(echo "{"; \
> for f in `grep _Unwind_ $< | sort`; do \
> echo " $$f = EXTERN DIRECT;"; \
> done; \
> echo "};" ) > $@
But the libcgcc-std.ver target is only exposed on the condition that shared
library building is enabled per libgcc/Makefile.in:
> ifeq ($(enable_shared),yes)
>
> # Map-file generation.
> ifneq ($(SHLIB_MKMAP),)
> libgcc.map: $(SHLIB_MKMAP) $(SHLIB_MAPFILES) $(libgcc-s-objects)
> { $(NM) $(SHLIB_NM_FLAGS) $(libgcc-s-objects); echo %%; \
> cat $(SHLIB_MAPFILES) \
> | sed -e '/^[ ]*#/d' \
> -e 's/^%\(if\|else\|elif\|endif\|define\)/#\1/' \
> | $(gcc_compile_bare) -E -xassembler-with-cpp -; \
> } | $(AWK) -f $(SHLIB_MKMAP) $(SHLIB_MKMAP_OPTS) > tmp-$@
> mv tmp-$@ $@
> libgcc_s$(SHLIB_EXT): libgcc.map
> mapfile = libgcc.map
> endif
>
> libgcc-std.ver: $(srcdir)/libgcc-std.ver.in
> sed -e 's/__PFX__/$(LIBGCC_VER_GNU_PREFIX)/g' \
> -e 's/__FIXPTPFX__/$(LIBGCC_VER_FIXEDPOINT_GNU_PREFIX)/g' < $< > $@
I found that moving the libgcc-std.ver target above the "ifeq
($(enable_shared),yes)" line to expose it unconditionally allowed the build to
continue.
