Executable not relinking if related static libraries are changed.

[Uttkarsh]

I am trying to build an executable which depends on static libraries,say a and b. When there are changes in a or b and we try to recompile the executable, it does not gets updated. It just assumes that all targets are built and there are no new changes.

Are these external libraries like:

lib a b ;
exe test : test.cpp a b ;

If so, that's kind of the expected behavior. Boost.Build just passes -la -lb and doesn't actually try to track down the actual location of the libraries. If you give the exact location with <file>/path/to/a.a, then the dependency should be added.
