Hi Reiner,

I had the same problem some weeks ago. After some information on this list i
also tried the same as you did and got exactly the same errormessages. 

After i had done some investigation, i found out that the problem is that
automake can not cope with some special features of GNU-Make like 
$(wildcard ...). Automake tries to find out which sources are contained in your
project and generates make rules in order to produce *.o files from these
sources. 

Since your solution describes the project sources with a wildcard construct
(which is not understood by automake), automake does not find *any* source file
and produces some senseless rules.

I did not find a good solution to this problem. The only workaround is to
handle the source files (normal source files an idl-generated ones) by hand
in the Makefile.am. This can be done by replacing the $(wildcard) constructs by
the filenames that would match this wildcard. Unfortunately this avoids every
file management from KDevelop... :-(


Bye, Marcus.
