Brad King a86e8fa69f ENH: Yet another attempt at warning for CMP0003.
- Give example code to avoid the warning
  - Make explanation more consise
  - Explicitly state this is for compatibility
  - Issue the warning for at most one target

Bill Hoffman ba7f0ab335 ENH: try to reduce the number of CMP0003 warnings that people see. Only report them for unique sets of libraries with no full path. Also add a message explaining the course of action that should be taken 2008-03-18 17:32:26 -04:00
Brad King d46ff28ac9 ENH: Convert CMAKE_LINK_OLD_PATHS to policy CMP0003.
- Policy is WARN by default so projects will build
    as they did in 2.4 without user intervention
  - Remove CMAKE_LINK_OLD_PATHS variable since it was
    never in a release and the policy supercedes it
  - Report target creation backtrace in warning message
    since policy should be set by that point

Brad King 34c76d4304 ENH: Use builtin chrpath instead of relinking ELF targets
- Add cmSystemTools::ChangeRPath method
  - Add undocumented file(CHRPATH) command
  - When installing use file(CHRPATH) to change the rpath
    instead of relinking
  - Remove CMAKE_CHRPATH lookup from CMakeFindBinUtils
  - Remove CMAKE_USE_CHRPATH option since this should
    always work

Brad King fd37a6ec3d ENH: Better linker search path computation.
- Use linker search path -L.. -lfoo for lib w/out soname
    when platform sets CMAKE_PLATFORM_USES_PATH_WHEN_NO_SONAME
  - Rename cmOrderRuntimeDirectories to cmOrderDirectories
    and generalize it for both soname constraints and link
    library constraints
  - Use cmOrderDirectories to order -L directories based
    on all needed constraints
  - Avoid processing implicit link directories
  - For CMAKE_OLD_LINK_PATHS add constraints from libs
    producing them to produce old ordering

Brad King 07be6bb87b ENH: When linking to versioned targets whose real file name is known pass the real name to the linker instead of the symlink name. 2008-02-06 13:34:44 -05:00
Brad King 847c8403fe BUG: Added TARGET_ARCHIVES_MAY_BE_SHARED_LIBS global property to help compute proper rpath information on AIX when shared libraries have names like "libfoo.a". 2008-02-04 15:22:10 -05:00
Brad King 82fcaebe28 ENH: Pass dependent library search path to linker on some platforms.
- Move runtime path ordering out of cmComputeLinkInformation
    into its own class cmOrderRuntimeDirectories.
  - Create an instance of cmOrderRuntimeDirectories for runtime
    path ordering and another instance for dependent library
    path ordering.
  - Replace CMAKE_DEPENDENT_SHARED_LIBRARY_MODE with explicit
    CMAKE_LINK_DEPENDENT_LIBRARY_FILES boolean.
  - Create CMAKE_LINK_DEPENDENT_LIBRARY_DIRS boolean.
  - Create variables to specify -rpath-link flags:
      CMAKE_SHARED_LIBRARY_RPATH_LINK_<LANG>_FLAG
      CMAKE_EXECUTABLE_RPATH_LINK_<LANG>_FLAG
  - Enable -rpath-link flag on Linux and QNX.
  - Documentation and error message updates

Brad King 2cff26fa52 ENH: Support linking to shared libs with dependent libs
- Split IMPORTED_LINK_LIBRARIES into two parts:
      IMPORTED_LINK_INTERFACE_LIBRARIES
      IMPORTED_LINK_DEPENDENT_LIBRARIES
  - Add CMAKE_DEPENDENT_SHARED_LIBRARY_MODE to select behavior
  - Set mode to LINK for Darwin (fixes universal binary problem)
  - Update ExportImport test to account for changes

Brad King 3a05425309 BUG: Move decision to switch library paths found in implicit link directories to use -l options from cmFindLibraryCommand to cmComputeLinkInformation. Existing projects may depend on find_library returning a full path. This slightly weakens cmComputeLinkInformation but is necessary for compatibility. 2008-01-31 07:50:40 -05:00
Brad King 319c4c4d80 ENH: Update cmInstallTargetGenerator to get the shared libraries linked by a target from cmComputeLinkInformation instead of duplicating the computation. 2008-01-29 15:47:18 -05:00
Brad King ffac622a85 ENH: Add cmTarget::GetLinkInformation method to allow several places in the generators to share link information while only computing it once per configuration for a target. Use it to simplify the chrpath feature. 2008-01-29 15:07:33 -05:00
Brad King 99b97dece8 ENH: Created cmComputeLinkDepends to compute link dependencies.
- This will be useful for imported library dependencies
  - Replaces old cmTarget analyze-lib-depends stuff for linking
  - Formalizes graph construction and dump
  - Explicitly represents dependency inferral sets
  - Use BFS of initial dependencies to preserve order

Brad King 48fddd602d BUG: Fix cmComputeLinkInformation cycle detection. 2008-01-23 15:56:17 -05:00
Brad King f27379e3f7 ENH: Added CMAKE_LINK_OLD_PATHS compatibility mode for linker search paths. 2008-01-23 15:22:38 -05:00
Brad King 09af624dee BUG: Fix generation of Watcom link lines.
- Work-around bug in Watcom command line parsing for spaces in paths.
  - Add 'library' option before libraries specified by file path.

Brad King ceb716575e BUG: When a library file name is linked without a path make sure the link type is restored after the -l option. 2008-01-22 10:05:27 -05:00
Brad King 96fd5909d9 ENH: Implement linking with paths to library files instead of -L and -l separation. See bug #3832
- This is purely an implementation improvement.  No interface has changed.
  - Create cmComputeLinkInformation class
  - Move and re-implement logic from:
      cmLocalGenerator::ComputeLinkInformation
      cmOrderLinkDirectories
  - Link libraries to targets with their full path (if it is known)
  - Dirs specified with link_directories command still added with -L
  - Make link type specific to library names without paths
    (name libfoo.a without path becomes -Wl,-Bstatic -lfoo)
  - Make directory ordering specific to a runtime path computation feature
    (look for conflicting SONAMEs instead of library names)
  - Implement proper rpath support on HP-UX and AIX.
