This patch fixes that and allows the build to continue. Bootstrapped on x86_64-apple-darwin23.0.0, i386-pc-solaris2.11, and sparc-sun-solaris2.11. 2023-07-11 Rainer Orth gcc/m2: * Make-lang.in (m2/boot-bin/mklink$(exeext)): Add $(LDFLAGS). --- diff --git a/gcc/m2/Make-lang.in b/gcc/m2/Make-lang.in index 6fb551f9a601..0fe671e540d8 100644 --- a/gcc/m2/Make-lang.in +++ b/gcc/m2/Make-lang.in @@ -1653,7 +1653,7 @@ m2/gm2-compiler-boot/gm2.a: m2/boot-bin/mc$(exeext) m2/boot-bin/mklink$(exeext): $(srcdir)/m2/tools-src/mklink.c -test -d $(@D) || $(mkinstalldirs) $(@D) - $(CXX) $(CFLAGS) -I$(srcdir)/m2 -Im2/gm2-libs-boot -Im2/gm2-compiler-boot -I$(srcdir)/m2/mc-boot-ch $(INCLUDES) $< -o $@ + $(CXX) $(CFLAGS) $(LDFLAGS) -I$(srcdir)/m2 -Im2/gm2-libs-boot -Im2/gm2-compiler-boot -I$(srcdir)/m2/mc-boot-ch $(INCLUDES) $< -o $@ m2/gm2-compiler-boot/$(SRC_PREFIX)%.h: $(srcdir)/m2/gm2-compiler-boot/%.def $(MCDEPS) -test -d $(@D) || $(mkinstalldirs) $(@D)
