So to answer my own post, here is a (as I find very hacked) solution: a) do not include the external libraries into the new sub project. I used this Makefile.am : http://pastebin.com/Pw8EeLrp b) do the linking in the binary, i.e. in ../src/Main. I modified the Makefile.am there to look like this: http://pastebin.com/RfJ5MQRx So the solution is to inlcude the external libraries via -lxxx where you also would include the subprojects libXXX.a and alter the _LDFLAGS to s.t. a direct path to the external libraries is given... (i.e. add -L/where/ever/libs) Although this works, (and as of now I don't intend to change it), I would be interested how to do this "properly"... Regards, Claus -- Claus Christmann, M.S.
