Really strange error... hmmmm...
first the BTW:
I see you have added -ldaemon and -lcommon also to your project... isn't
this already a linking conflict itself?? Binding daemon and common as
shared lib _and_ as static lib to it?

But this isn't the fault at all I guess, so I keep in mind some stuff,
which maybe apply on your problem:
1) Your new c++ framework works with gmake and not with make (but make
is still on your system)

2) /users2/mitarb/ulli/kdev/test/test/daemon is a mountpoint (done with
smbmount e.g.) which kills some permission flags?

3) Your Makefile.am was patched to make a shared lib of "./daemon" (and
"./common") instead of a static lib, but the parent directory's
Makefile.am (i.e. /users2/mitarb/ulli/kdev/test/test) uses "./daemon" as
static lib.

To check out what it is, some other hints:
 
1) Build your project from the scratch by the console doing the
following:
cd /users2/mitarb/ulli/dev/test
make distclean
rm config.cache
make -f Makefile.dist
configure [with your options...]
make

2) check the /users2/mitarb/ulli/kdev/test/test/daemon/Makefile.am
Is there a option like "lib_LTLIBRARIES = libdaemon.la" so this means
daemon is wanted to be used as distributed "libtool archive" (to be
installed into $(libdir))
If there is an option like "noinst_LIBRARIES = libdaemon.a" means static
lib, not installed, but linked to the project.

seems that libdaemon is a libtool library... and should have the
extension .la
and not .a ....
