Re: Problems getting dependencies compiled before executable....

[cs]

Thanks for the reply.  I would do it as you said also.

My goal was to find out why _DEPENDENCIES is not doing

what I think it should.  Even though this example is

contrived, the same problem happens in examples that

are not.


If a dependency of a target is not built, then Makefile

should build the dependency first.  That is not what

is happening here.  Why can't Makefile go to right

directory to build the dependency???

   Why not have the executable outside and the library
   in a subdirectory. That is how I put my libraries.

   src/main.c
   src/helperfunctions/helperfunctions.a

   with regards,
   Santosh.
