What exactly did you use on the command line to build udev in this
manner? You should be able to specify the CROSS_COMPILE variable on the
build line, and have it work properly.

Try:
make CROSS_COMPILE=arm-uclibc-linux-
instead.
And please don't take email threads off of the mailing list, it's rude
to the rest of the members, and the archives.

Hello
make CROSS_COMPILE=arm-uclibc-linux-
works fine.
Thanks for pointing this out to me - but I don't understand why. Please
give me an idea why
CROSS_COMPILE=arm-uclibc-linux- make
doesn't work.
Thanks, Jonas

this declares CROSS_COMPILE as a make variable

Now this is a CROSS_COMPILE=arm-uclibc-linux- shell variable. Make may
read it or not. IIRC there is an option that forces make to import the
hole environment.

Arguments to make that are variables, overwrite the ones
from the Makefile:

The environment variable, is imported:
http://www.gnu.org/software/make/manual/html_node/Environment.html#Environment
but cleared by the Makefile for some reason, I don't know. We
can probably remove that empty assignment.
