Thanks.

But now I get the following message:

cd e:\develop\RailSys\
bjam msvc
XXX
e:/libraries/boost_cvs/tools/build/v2/build\virtual-target.jam:797: in 
virtual-target.register-actual-name from module virtual-target
error: Duplicate name of actual target: <p..\..
\libraries\flexlm\v9.2\i86_n3>lmgr_md.lib
previous virtual target { %.no-action-lmgr_md.STATIC_LIB }
another virtual target { %.no-action-lmgr_md.STATIC_LIB }

[full output attached]

This has been bothering me on linux for some time, but I didn't take the 
time to write a bug report.

What happens here is the usage of MacroVisions FlexLm.

I have declared 

# Build library-target for flexlm
lib flexlm : : <file>$(FLEXLM_ROOT)/i86_n3/lmgr_md.lib ;
alias flex : $(FLEXLM_ROOT)/i86_n3/lm_new.obj flexlm ; 

and in 
: requirements
# Uses Flexlm
<include>$(FLEXLM_ROOT)/machind
<library>/RailSys//flex
: usage-requirements
<include>$(FLEXLM_ROOT)/machind
<library>/RailSys//flex

This triggers 2 things:
1) First, this warning of duplicate target, because each library links 
against flexlm (and the lm_new.obj file containing the encryption keys) 
and then the exe is linked against flexlm, too. 
Or my 3 spezial files which must be compiled with <optimizion>off 
trigger this. I'm not quite sure about that.

2) The resulting link action for the exe target contains 1 occurence of 
the flexlm library and lm_new.obj for _each_ V2-generated library.
This kills gcc because it can't link the same .o file twice and link.exe 
at leads spills out a warning. 

When you need a test case, I'll try to contruct one, but this migth 
take some time

Yours, 

Jürgen
