How many times you tried to install the QtSDK?

First report from you 4x sysroot directory.
(result-->wrong path)
Second report you got 3x4 sysroot directories.
(result-->much to long path)

Maybe some path variable is wrong in Windows??
So I guess during installation somewhere a path gets added and not replaced?

In linux you have a config.sh inside your target which makes the environment variables.

c:/qtsdk/madde/targets/harmattan_XXXX/config.sh

SYSROOT_DIR=
SYSROOT_DIR_NATIVE=

Do you have also somewhere this values.

When I am at home I have a look into my windows QtSDK and will investigate your problem.
