[U-Boot-Users] u-boot compile problem

[Luca Contini]

Sorry for the subject in previous e-mail...

Hi all,
I've downloaded the latest u-boot-1.1.1 and I'm trying to compile,
but I get this error at the end... any idea?
Toolchain: cross-3.2  (from arm linux)
regards

Your toolchain is broken, and seriously. It cannot find  one  of  the
libraries it thinks it needs (libfloat).

This is off topic here. Please ask such questions on the
linux-arm-toolchain mailing list.

You run into the same problem i had.
It is not a problem with the toolchain, it is due to the fact how the makefile
in examples is written.

When you first run make without arm-linux-gcc in the path make does a lot, but it
created only empty .depend files (because of compiler not found).
Afterwards you include arm-linux-gcc in the path and run make again.
Everything is running then except the examples directory.

Make does not compile hello_world.c, instead it uses a builtin implicit rule to
make hello_world (there is no dependency from OBJS and the explicit dependency for
hello_world.o is missing, because of empty .depend). When you run make -r (no
builtin implicit rules) it works.

Work around:
make clobber (deletes your wrong .depend)
mkconfig ...
adding arm-linux-gcc to your path
make

Hint to Wolfgang:
If you add OBJS to the all rule in Makefile for examples, it will work in any case.
all:	.depend $(LIB) $(OBJS) $(SREC) $(BIN)

Added, thanks!
