| // the dependency graph for those libraries. |
| // |
| // 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 |
| // cyclic dependencies, so this is probably not a big deal. Note that |
| // the link line is always correct, just not necessary optimal. |
