Hello,
i'm not sure this is the right place to report this. Please direct me elsewhere
if it's not.
I'm trying to build generic binaries for lilypond (lilypond.org), using a x86
pc targetting linux/ppc. I'm building a cross-compiler against the
Debian/stable libs/headers.
My problem is that libgcc_s.so links in the __libc_stack_end symbol
(ppc_linux_aux_vector () in config/rs6000/linux-unwind.h )
This symbol has differing versions across platforms (GLIB_2.1 on Fedora Core,
Yellow Dog Linux and GLIBC_PRIVATE on Debian/stable), so it's not possible to
build PPC binaries that run on all linux/ppc distributions.
I could try patching GCC sources, to simulate a stupid PPC CPU, but it would be
nice if this worked out of the box, ie. if ppc_fallback_frame_state() could
determine CPU characteristics without looking at __libc_stack_end.
