From cbd8f9302c9a04bf4fe72a3a1a641faf07614552 Mon Sep 17 00:00:00 2001 From: Andrew Senkevich Date: Thu, 8 Dec 2016 17:25:59 +0300 Subject: Install libm.a as linker script (bug 20539). Install libm.a as linker script to avoid static link fail w/o passing additional -lmvec option while building with GCC >= 6.1. [BZ #20539] * math/Makefile (install-lib-ldscripts): Add libm.a. (install_subdir): Remove. (install-others): Add. ($(inst_libdir)/libm.a): Add rule for installation as linker script. * Makerules (install-lib.a): Filter out install-lib-ldscripts. --- math/Makefile | 19 +++++++++++++++---- 1 file changed, 15 insertions(+), 4 deletions(-) (limited to 'math') diff --git a/math/Makefile b/math/Makefile index 848b093863..49556f69c6 100644 --- a/math/Makefile +++ b/math/Makefile @@ -128,10 +128,10 @@ generated += $(foreach s,.c .S,$(call type-foreach, $(calls:s_%=m_%$(s)))) routines = $(call type-foreach, $(calls)) ifeq ($(build-mathvec),yes) -# We need to install libm.so as linker script -# for more comfortable use of vector math library. -install-lib-ldscripts := libm.so -install_subdir: $(inst_libdir)/libm.so +# We need to install libm.so and libm.a as linker scripts +# for transparent use of vector math library. +install-lib-ldscripts := libm.so libm.a +install-others = $(inst_libdir)/libm.so $(inst_libdir)/libm.a $(inst_libdir)/libm.so: $(common-objpfx)format.lds \ $(libm) \ $(libmvec) \ @@ -142,6 +142,17 @@ $(inst_libdir)/libm.so: $(common-objpfx)format.lds \ 'AS_NEEDED ( $(libdir)/libmvec_nonshared.a $(slibdir)/libmvec.so$(libmvec.so-version) ) )' \ ) > $@.new mv -f $@.new $@ + +$(inst_libdir)/libm.a: $(common-objpfx)format.lds \ + $(libm) \ + $(libmvec) \ + $(+force) + (echo '/* GNU ld script'; echo '*/';\ + cat $<; \ + echo 'GROUP ( $(libdir)/libm-$(lib-version).a $(libdir)/libmvec.a )' \ + ) > $@.new + cp $(objpfx)libm.a $(inst_libdir)/libm-$(lib-version).a + mv -f $@.new $@ endif # Rules for the test suite. -- cgit v1.2.3
