Brad King 0fb5b2c88c Invalidate target link info when necessary
In cmTarget we compute the link implementation, link interface, and link
closure structures on-demand and cache the results.  This commit teaches
cmTarget to invalidate results after a LINK_INTERFACE_* property changes
or a new link library is added.  We also clear the results at the end of
the Configure step to ensure the Generate step uses up-to-date results.

Brad King daa2f3aa41 Combine duplicate code in target property methods
In cmTarget::SetProperty and cmTarget::AppendProperty we check whether
changing the property invalidates cached information.  The check was
duplicated in the two methods, so this commit moves the check into a
helper method called from both.

Brad King 78f0811628 Create explicit cmTarget::FinishConfigure step
This method is called during ConfigureFinalPass on every target.  It
gives each target a chance to do some final processing after it is known
that no more commands will affect it.  Currently we just call the old
AnalyzeLibDependencies that used to be called directly.

Brad King 1e48243591 Introduce "build feature" lookup framework
This creates cmTarget::GetFeature and cmMakefile::GetFeature methods to
query "build feature" properties.  These methods handle local-to-global
scope and per-configuration property lookup.  Specific build features
will be defined later.

Brad King 96afb12087 Convert CMake to OSI-approved BSD License
This converts the CMake license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified
versions to be plainly marked.  We also update the CMake copyright to
cover the full development time range.

Brad King 4224513cce Save source dependencies from custom command trace
In each target we trace dependencies among custom commands to pull in
all source files and build rules necessary to complete the target.  This
commit teaches cmTarget to save the inter-source dependencies found
during its analysis.  Later this can be used by generators that need to
topologically order custom command rules.

Brad King 4eb5f1bef6 Cleanup cmTarget source file list representation
This teaches cmTarget to use a set of cmSourceFile pointers to guarantee
unique insertion of source files in a target.  The order of insertion is
still preserved in the SourceFiles vector.

Brad King 69251f7549 Define 'multiplicity' for cyclic dependencies
We create target property "LINK_INTERFACE_MULTIPLICITY" and a per-config
version "LINK_INTERFACE_MULTIPLICITY_<CONFIG>".  It sets the number of
times a linker should scan through a mutually dependent group of static
libraries.  The largest value of this property on any target in the
group is used.  This will help projects link even for extreme cases of
cyclic inter-target dependencies.

Brad King 463b3f03bd Create cmTarget DLL query methods
We creates methods IsDLLPlatform() and HasImportLibrary().  The former
returns true on Windows.  The latter returns whether the target has a
DLL import library.  It is true on Windows for shared libraries and
executables with exports.

Brad King 19792bf30e ENH: Consider link dependencies for link language
This teaches cmTarget to account for the languages compiled into link
dependencies when determining the linker language for its target.

We list the languages compiled into a static archive in its link
interface.  Any target linking to it knows that the runtime libraries
for the static archive's languages must be available at link time.  For
now this affects only the linker language selection, but later it will
allow CMake to automatically list the language runtime libraries.

Brad King 173448d988 ENH: Pass config to cmTarget::GetLinkerLanguage
This passes the build configuration to most GetLinkerLanguage calls.  In
the future the linker language will account for targets linked in each
configuration.
2009-07-08 13:04:04 -04:00
Brad King a3a046643a ENH: Pass config to cmTarget RPATH install methods
This passes the build configuration to cmTarget methods IsChrpathUsed
and NeedRelinkBeforeInstall.  Later these methods will use the value.
2009-07-08 13:03:47 -04:00
Brad King 7c67524dfa ENH: Introduce cmTarget::LinkImplementation API
The new method centralizes loops that process raw OriginalLinkLibraries
to extract the link implementation (libraries linked into the target)
for each configuration.  Results are computed on demand and then cached.
This simplifies link interface computation because the default case
trivially copies the link implementation.

Brad King aef8fe509b COMP: Pimplize cmTarget ImportInfo and OutputInfo
These member structures are accessed only in the cmTarget implementation
so they do not need to be defined in the header.  This cleanup also aids
Visual Studio 6 in compiling them.

Brad King 94a4a614ca STYLE: Fix comment on cmTarget::LinkInterface
The comment had a typo and was longer than necessary.
2009-07-07 10:56:51 -04:00
Brad King 34f78ee552 ENH: Simplify cmTarget link interface storage
This makes the LinkInterface struct a member of cmTarget, pimplizes the
config-to-interface map, and stores interface instances by value.
2009-07-07 09:45:29 -04:00
Brad King a608467180 ENH: Simpler cmTarget::GetLinkerLanguage signature
This method previously required the global generator to be passed, but
that was left from before cmTarget had its Makefile member.  Now the
global generator can be retrieved automatically, so we can drop the
method argument.

Brad King 06b0a692f4 ENH: Centralize default link interface computation
When LINK_INTERFACE_LIBRARIES is not set we use the link implementation
to implicitly define the link interface.  These changes centralize the
decision so that all linkable targets internally have a link interface.

Brad King 26df00f83a ENH: Move CMP0004 check into cmTarget
This moves code implementing policy CMP0004 into cmTarget::CheckCMP0004.
The implementation is slightly simpler and can be re-used outside of
cmComputeLinkDepends.

Brad King 82a8c6b0c7 ENH: Exception safe link interface computation
This fixes cmTarget::GetLinkInterface to compute and return the link
interface in an exception-safe manner.  We manage the link interface
returned by cmTarget::ComputeLinkInterface using auto_ptr.
2009-07-06 16:24:32 -04:00
Brad King 275c21d351 ENH: Refactor target output dir computation
This creates cmTarget::GetOutputInfo to compute, cache, and lookup
target output directory information on a per-configuration basis.  It
avoids re-computing the information every time it is needed.
2009-07-03 10:33:59 -04:00
Brad King 392b38cef7 ENH: Remove cmTarget internal type arguments
Internally cmTarget was passing the target type in several name
computation signatures to support computation of both shared and static
library names for one target.  We no longer need to compute both names,
so this change simplifies the internals by using the GetType method and
dropping the type from method signatures.

Brad King bcb9a479db ENH: Remove cmTarget::GetExecutableCleanNames
This method was redundant with GetExecutableNames.

Brad King 430cc2b4b7 ENH: Always imply CLEAN_DIRECT_OUTPUT target prop
This property was left from before CMake always linked using full path
library names for targets it builds.  In order to safely link with
"-lfoo" we needed to avoid having both shared and static libraries in
the build tree for targets that switch on BUILD_SHARED_LIBS.  This meant
cleaning both shared and static names before creating the library, which
led to the creation of CLEAN_DIRECT_OUTPUT to disable the behavior.

Now that we always link with a full path we do not need to clean old
library names left from an alternate setting of BUILD_SHARED_LIBS.  This
change removes the CLEAN_DIRECT_OUTPUT property and instead uses its
behavior always.  It removes some complexity from cmTarget internally.
2009-05-01 10:38:35 -04:00
Brad King 2740db5ede ENH: Allow more specification of target file names
This creates target properties ARCHIVE_OUTPUT_NAME, LIBRARY_OUTPUT_NAME,
and RUNTIME_OUTPUT_NAME, and per-configuration equivalent properties
ARCHIVE_OUTPUT_NAME_<CONFIG>, LIBRARY_OUTPUT_NAME_<CONFIG>, and
RUNTIME_OUTPUT_NAME_<CONFIG>.  They allow specification of target output
file names on a per-type, per-configuration basis.  For example, a .dll
and its .lib import library may have different base names.

For consistency and to avoid ambiguity, the old <CONFIG>_OUTPUT_NAME
property is now also available as OUTPUT_NAME_<CONFIG>.

See issue #8920.
2009-05-01 09:45:43 -04:00
Brad King 617eb981d4 ENH: Refactor target output file type computation
This creates method cmTarget::GetOutputTargetType to compute the output
file type 'ARCHIVE', 'LIBRARY', or 'RUNTIME' from the platform and
target type.  It factors out logic from the target output directory
computation code for later re-use.
2009-05-01 09:45:19 -04:00
Brad King d0ed46e3d6 ENH: Define target-specific support directories
This creates method cmTarget::GetSupportDirectory to compute a
target-specific support directory in the build tree.  It uses the
"CMakeFiles/<name>.dir" convention already used by the Makefile
generators.  The method will be useful for any code that needs to
generate per-target information into the build tree for use by CMake
tools that do not run at generate time.

Brad King 3c5cf1bb8c ENH: Allow a custom list of debug configurations
Create a DEBUG_CONFIGURATIONS global property as a way for projects to
specify which configuration names are considered to be 'debug'
configurations.
2008-09-04 17:34:25 -04:00
Brad King fe98e57e38 ENH: Disallow link-type keywords in link interface
The LINK_INTERFACE_LIBRARIES target property may not contain the
"debug", "optimized", or "general" keywords.  These keywords are
supported only by the target_link_libraries (and link_libraries) command
and are not a generic library list feature in CMake.  When a user
attempts to add one of these keywords to the property value, we now
produce an error message that refers users to alternative means.

Brad King 061d20be38 ENH: Add UNKNOWN type for IMPORTED libraries
When creating an IMPORTED target for a library that has been found on
disk, it may not be known whether the library is STATIC or SHARED.
However, the library may still be linked using the file found from disk.
Use of an IMPORTED target is still important to allow per-configuration
files to be specified for the library.

This change creates an UNKNOWN type for IMPORTED library targets.  The
IMPORTED_LOCATION property (and its per-config equivalents) specifies
the location of the library.  CMake makes no assumptions about the
library that cannot be inferred from the file on disk.  This will help
projects and find-modules import targets found on disk or specified by
the user.

Brad King b93f0318fe ENH: Support full-path libs w/out valid names.
This change introduces policy CMP0008 to decide how to treat full path
libraries that do not appear to be valid library file names.  Such
libraries worked by accident in the VS IDE and Xcode generators with
CMake 2.4 and below.  We support them in CMake 2.6 by introducing this
policy.  See policy documentation added by this change for details.

Brad King da4f142cc1 ENH: Add full target version signature cmTarget::GetTargetVersion. 2008-07-09 10:09:00 -04:00
Brad King 771bdb7ef8 BUG: Make sure all source files are found before generating.
- Previously this was done implicitly by the check for a target
    link language which checked all source full paths.
  - The recent change to support computing a link language without
    finding all the source files skipped the implicit check.
  - This change adds an explicit check to find all source files.

- Place the built library in foo.framework/Versions/A/foo
  - Do not create unused content symlinks (like PrivateHeaders)
  - Do not use VERSION/SOVERSION properties for frameworks
  - Make cmTarget::GetDirectory return by value
  - Remove the foo.framework part from cmTarget::GetDirectory
  - Correct install_name construction and conversion on install
  - Fix MACOSX_PACKAGE_LOCATION under Xcode to use the
    Versions/<version> directory for frameworks
  - Update the Framework test to try these things

Brad King bf4cef9d5c ENH: Add policy CMP_0004 to require library names to have no leading or trailing whitespace. Replace previous check of CMAKE_BACKWARDS_COMPATIBILITY against version 2.4 with the policy. 2008-03-13 16:35:39 -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
2008-03-13 16:23:18 -04:00
Brad King f7f03347a6 ENH: Improve new error/warning message generation
- Add cmListFileBacktrace to record stack traces
  - Move main IssueMessage method to the cmake class instance
    (make the backtrace an explicit argument)
  - Change cmMakefile::IssueMessage to construct a backtrace
    and call the cmake instance version
  - Record a backtrace at the point a target is created
    (useful later for messages issued by generators)

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
2008-03-01 12:51:07 -05:00
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 16186ec18c BUG: Remove InstallNameFixupPath from cmTarget and cmInstallTargetGenerator.
- Motivation:
    - It depended on the order of installation
    - It supported only a single destination for each target
    - It created directory portions of an install name without user request
  - Updated ExportImport test to install targets in an order that expoed
    this bug
2008-02-01 13:08:12 -05:00
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
2008-01-31 15:45:31 -05:00
Brad King 7902bc06aa ENH: Implemented link-interface specification feature.
- Shared libs and executables with exports may now have
    explicit transitive link dependencies specified
  - Created LINK_INTERFACE_LIBRARIES and related properties
  - Exported targets get the interface libraries as their
    IMPORTED_LINK_LIBRARIES property.
  - The export() and install(EXPORT) commands now give
    an error when a linked target is not included since
    the user can change the interface libraries instead
    of adding the target.
