[U-Boot-Users] still trying with the examples directory on release 1.1.2 and Walnut config

[U-Boot-Users] still trying with the examples directory on release 1.1.2 and Walnut config

[John Davis]

Hello

I managed to build the lib_generic/libgeneic.a file by manually performing a
make at the top-level by
specifing make lib_generic/libgeneric.a.

However, I do not get this library included when I try to build the examples
directory. Even if I hardcode the
examples directory Makefile so that it includes the lib_generic directory,
it still fails to build the examples
directory. See below.

I have similar results if I change the order of the libgeneric specifier.
ie.
-L../lib_generic -lgeneric
-L/opt/fld_fakeroot/opt/mcp/ppc/bin/../lib/gcc-lib/ppc-linux/3.3.3 -lgcc

Please advise. Its scary that putc does even work.

Your toolchain must be *seriously* broken. Which environment are  you
working in?

Find a PC with a somewhat recent version of Linux installed, download
and install the ELDK, and forget about your problems ;-)

I may be wrong, but libgeneric.a is only used by U-Boot and NOT by 
examples. Examples use the U-Boot ABI which provides access to 
libgeneric.a level functions as defined by include/exports.h

Its not scary, its done through the ABI.

ppc_405-ld -g  -Ttext 0x40000 \
         -o hello_world -e hello_world hello_world.o libstubs.a \

This is my 1.1.2 build command - there is NO generic lib linked in! It 
is NOT needed because U-Boot ABI provides those library functions.
