Re: Bug while cross compiling for powerpc

[ClÃment Foucher <Clement dot FOUCHER at unice dot fr>]

Ok, here is what I got now :

Configure line :

CC=/opt/eldk/usr/bin/powerpc-linux-gcc 
CXX=/opt/eldk/usr/bin/powerpc-linux-g++ CFLAGS='-O2 -g' 
AR=/opt/eldk/usr/bin/powerpc-linux-ar RANLIB=/opt/eldk/usr/bin/ranlib 
../glibc/configure --prefix=/opt/glibc --build=x86_64-linux --host=powerpc-linux 
--target=powerpc-linux --without-fp --with-tls --with-binutils=/opt/eldk/usr/bin 
--enable-add-ons=ports,nptl

But I don't put "--with-cpu=440" since I got always the same error message
("Checking sysdep dirs... configure: error: The 440 subspecies of PowerPc is
not supported")

Make then halts on the following message:

What is nscd? It seems that this is a link problem: do I miss a library?
