Have you figured out why this is happening? I think it's a GCC bug which should be reported; we've had similar problems with bogus libgcc_eh dependencies on ARM in musl, but fortunately they're much easier for us to solve. > Signed-off-by: Carmelo Amoroso <carmelo.amor...@st.com> > Signed-off-by: Filippo Arcidiacono <filippo.arcidiac...@st.com> > --- > ldso/ldso/Makefile.in | 2 ++ > 1 files changed, 2 insertions(+), 0 deletions(-) > > diff --git a/ldso/ldso/Makefile.in b/ldso/ldso/Makefile.in > index 91165c6..65f9a46 100644 > --- a/ldso/ldso/Makefile.in > +++ b/ldso/ldso/Makefile.in > @@ -30,6 +30,8 @@ CFLAGS-ldso/ldso/$(TARGET_ARCH)/ := $(CFLAGS-ldso) > > CFLAGS-ldso.c := -DLDSO_ELFINTERP=\"$(TARGET_ARCH)/elfinterp.c\" > $(CFLAGS-ldso) > > +CFLAGS-OMIT-ldso.c = -fasynchronous-unwind-tables > + How does this work? -fasynchronous-unwind-tables is the GCC default. You need -fno-asynchronous-unwind-tables to turn them off. Rich _______________________________________________ uClibc mailing list uClibc@uclibc.org http://lists.busybox.net/mailman/listinfo/uclibc
