Hi,

I got a problem with libraries and g++. 
Preconditions
	- two directories with two objects, each with its own librarys
	- the object wich will be created from the other object was inserted first 		
	   in the project

then the Makefile.am file in the maindirectory (where also the main.cpp file 
is located) looks like this:

######## begin of Makefile.am #########
####### kdevelop will overwrite this part!!! (begin)##########
bin_PROGRAMS = knowledgebase
knowledgebase_SOURCES = main.cpp
knowledgebase_LDADD   = ./network/libnetwork.a ./global/libglobal.a  
# <<<<<<<<  the above line is important

SUBDIRS = docs network global

EXTRA_DIST = main.cpp connect.h init.h central.h listen.h

####### kdevelop will overwrite this part!!! (end)###########
######### end of Makefile.am #########

If I compile the project with this settings, I get the following error:
./global/libglobal.a(master.o): In function 
`master::initialize_net(basic_string<char, string_char_traits<char>, 
__default_alloc_template<true, 0> >, unsigned int)':
master.o(.text+0x20e): undefined reference to `watchout::watchout(unsigned 
int)'

If I change the sequence in the mentioned line to 
knowledgebase_LDADD   = ./global/libglobal.a  ./network/libnetwork.a 
everything works fine.

The problem is, that this line was created automatically  by kdevelop. Is it 
possible to introduce a check, so that kdevelop will reorder this lines to 
prevent this error?

Cheers
Hartmut
