Hi,
During buildroot for PPC, I had "undefined reference to copysignl" error,
but if I uncheck BR2_GCC_SHARED_LIBGCC it compiles ok.
Can I somehow use soft float support with shared lib for ppc?
Regards,
Nuno

Something like
http://gcc.gnu.org/ml/gcc-patches/2008-10/msg00237.html
maybe ?

Well, this patch was controversial it seems. The OpenWRT guys have
instead integrated a fix for uClibc:
https://dev.openwrt.org/browser/trunk/toolchain/uClibc/patches-0.9.30.1/450-powerpc_copysignl.patch?rev=18178

Hi,
I'm a kind of rookie so how can I apply this patch? Is it included in
some buildroot snapshot?
Thanks + Regards,
Nuno
