// Also, we will leave the original link line intact; we will just add any
|
|
// dependencies that were missing.
|
|
//
|
|
// There is a problem with recursive external libraries
|
|
// (i.e. libraries with no dependency information that are
|
|
// recursively dependent). We must make sure that the we emit one of
|
|
// the libraries twice to satisfy the recursion, but we shouldn't
|
|
// emit it more times than necessary. In particular, we must make
|
|
// sure that handling this improbable case doesn't cost us when
|
|
// dealing with the common case of non-recursive libraries. The
|
|
// solution is to assume that the recursion is satisfied at one node
|
|
// of the dependency tree. To illustrate, assume libA and libB are
|
|
// extrenal and mutually dependent. Suppose libX depends on
|
|
// libA, and libY on libA and libX. Then
|
|
// TARGET_LINK_LIBRARIES( Y X A B A )
|
|
// TARGET_LINK_LIBRARIES( X A B A )
|
|
// TARGET_LINK_LIBRARIES( Exec Y )
|
|
// would result in "-lY -lX -lA -lB -lA". This is the correct way to
|
|
// specify the dependencies, since the mutual dependency of A and B
|
|
// is resolved *every time libA is specified*.
|
|
//
|
|
// Something like
|
|
// TARGET_LINK_LIBRARIES( Y X A B A )
|
|
// TARGET_LINK_LIBRARIES( X A B )
|
|
// TARGET_LINK_LIBRARIES( Exec Y )
|
|
// would result in "-lY -lX -lA -lB", and the mutual dependency
|
|
// information is lost. This is because in some case (Y), the mutual
|
|
// dependency of A and B is listed, while in another other case (X),
|
|
// it is not. Depending on which line actually emits A, the mutual
|
|
// dependency may or may not be on the final link line. We can't
|
|
// handle this pathalogical case cleanly without emitting extra
|
|
// libraries for the normal cases. Besides, the dependency
|
|
// information for X is wrong anyway: if we build an executable
|
|
// depending on X alone, we would not have the mutual dependency on
|
|
// A and B resolved.
|
|
//
|
|
// IMPROVEMENTS:
|
|
// -- The current algorithm will not always pick the "optimal" link line
|
|
// when recursive dependencies are present. It will instead break the
|
|
// cycles at an aribtrary point. The majority of projects won't have
|
|
// cyclic dependencies, so this is probably not a big deal. Note that
|
|
// the link line is always correct, just not necessary optimal.
