Boot.lib is one of 5 .lib's I am trying to link together.

Right now I am using LFLAGS =3D -nostartfiles -fno-builtin -nostdlib=20
And I am where I have started with arm-elf-ld.=20
The only error is:

..\..\hardware\hardware_arm\lib\hardware.lib: In function `hw_stop_measure'=
:
k_watchdog.c:(.text+0x98c): undefined reference to `__udivsi3'

In this function, the code-line he complains about is:
t_100ns =3D ( diff * 10 ) / 49;

Where t_100ns and diff are "unsigned long"s.=20

Then I'd say, do not link against boot.lib or add __udivsi3 to your
project (the bootstrap sources from Atmel have it).

Ok i got it solved:

Let me explain now how it has gone all the way up here:

I used at first arm-elf-ld. There i had this error:

..\..\hardware\hardware_arm\lib\hardware.lib: In function `hw_stop_measure':
k_watchdog.c:(.text+0x98c): undefined reference to `__udivsi3'

than i used arm-elf-gcc. with "no option!!", and had tons of errors.
finally i used "-nostartfiles -fno-builtin -nostdlib" as linking options, and had the same error that i had with arm-elf-ld
there, the problem was, (i guess), since i used -nostdlib with generating every .lib, he could not find `__udivsi3'.
When i used -nostdlib in one of the libs and not in the other, then it did not complain about anything.

I thought, it might help the future searches..

Thanks to 42Bastian, and everybody..

Mit freundlichem Gruß / Best regards

Ok, it seems you are not building a library, your are building a
relocatable object. Libraries are build with "ar" and are more flexible,
as "ld" just picks what it wants.
