Hey Guys,
 
I want to link all my programs against one library. When i'm in a subdirectory i get the error: "Unable to find file or target named"...
 
 This is what my Jamroot looks like:
 lib boostsystem : : <name>boost_system ;
 explicit boostsystem ;
 project : default-build release 
         : requirements <cxxflags>"-std=gnu++0x" 
         : requirements <include>.
         : requirements <library>boostsystem
         : build-dir ./bin
         ;
 #exe sertest : samples/sertest.cpp ;
 build-project samples ;
 
 The samples/Jamfile contains only the line:
 exe sertest : sertest.cpp ;
 
 By typing bjam I get the errormessage:
 error: Unable to find file or target named
 error:     'boostsystem'
 error: referred from project at
 error:     'samples'
 
 When I uncomment the secondlast line of the Jamrootfilie, and comment  the lastline, my sampleapplication compiles with no error. I know that  this is not the way to link against boost, but this is only an  example... I tried so much. Adding a slash( and much more) to the  <library> argument... It works too when I add the dependency  ../boostsystem to the samples/Jamfile-line, but thats the thing i want  to avoid with the default rule...
 
 I don't know where the problem is. I read so much documentation, and it  is so frustrating. Maybe I'm to stupid too get the concept behind  boost-bind. I had so many problems with setting different  compileroptions, crosscompilation, seting the linkingpath....
 
 I hope someone can help me...
