The commit "Consider link dependencies for link language" taught CMake to propagate linker language preference from languages compiled into libraries linked by a target. It turns out this should only be done for some languages, such as C++, because normally the language of the program entry point (main) should be used. We introduce variable CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES to tell CMake whether a language should propagate its linker preference across targets. Currently it is true only for C++.

|
|
//
|
|
// The latter is done using the cache entries that record the
|
|
// dependencies of each library.
|
|
//
|
|
// The former is a more thorny issue, since it is not clear how to
|
|
// determine if two libraries listed on the link line refer to the a
|
|
// single library or not. For example, consider the link "libraries"
|
|
// /usr/lib/libtiff.so -ltiff
|
|
// Is this one library or two? The solution implemented here is the
|
|
// simplest (and probably the only practical) one: two libraries are
|
|
// the same if their "link strings" are identical. Thus, the two
|
|
// libraries above are considered distinct. This also means that for
|
|
// dependency analysis to be effective, the CMake user must specify
|
|
// libraries build by his project without using any linker flags or
|
|
// file extensions. That is,
|
|
// LINK_LIBRARIES( One Two )
|
|
// instead of
|
|
// LINK_LIBRARIES( -lOne ${binarypath}/libTwo.a )
|
|
// The former is probably what most users would do, but it never
|
|
// hurts to document the assumptions. :-) Therefore, in the analysis
|
|
// code, the "canonical name" of a library is simply its name as
|
|
// given to a LINK_LIBRARIES command.
|
|
//
|
|
// 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
