* multiarch: Treat lib/<arch> as implicit link dir (#12326)Modestas Vainius2011-07-271-0/+12
| | | | | Add multiarch library directories to the set of implicit link directories. In particular, this keeps lib/<arch> out of R(UN)PATH.
* Add target property LINK_SEARCH_START_STATIC to aid static linkingBrad King2011-03-031-3/+3
| | | | | | | | | Commit afd7d4ca (Add target property LINK_SEARCH_END_STATIC, 2008-01-31) defined a property to ensure that static runtime libraries get selected. Add a property to specify that all libraries whose type is unknown, such as "-lm", should be assumed static. Furthermore it assumes that an option such as "-static" is also used so that no initial -Bstatic is needed.
* Prefer non-empty prefixes when matching lib names (#11468)Brad King2010-11-181-1/+1
| | | | | | | | | In cmComputeLinkInformation we match library names with a regular expression, possibly extracting the 'lib' prefix. The regex component to match the prefix always allows an empty prefix to be matched, as in "(lib|)". Avoid every adding an empty prefix option earlier in the regex, as in "(|lib|)", because it will be preferred and 'lib' will never match.

* OpenBSD: Work-around static/runtime linker inconsistencyChuck Atkins2010-03-261-0/+10
| | | | | | | Detect the runtime linker's search path and add to the compile time linker's search path. This is needed because OpenBSD's static linker does not search for shared library dependencies in the same places as the runtime linker.

* Convert CMake to OSI-approved BSD LicenseBrad King2009-09-281-14/+9
| | | | | | | 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.
* Factor implicit link info addition into methodsBrad King2009-08-241-28/+41
| | | | | | | In cmComputeLinkInformation::Compute we add implicit link information from languages other than the linker language to the end of the link line. This factors out that code into separate methods to improve readability and organization.
* BUG: Do not filter non-library implicit link itemsBrad King2009-07-281-1/+7
| | | | | | | We list implicit link items of languages linked into a target but filter them by the implicit libraries known to be passed by the main linker language. Implicit link flags like "-z..." should not be filtered out because they are not libraries.
* BUG: Always pass linker flags untouchedBrad King2009-07-281-21/+23
| | | | | | | | In cmComputeLinkInformation we recognize link options that look like library file names, but pass flags starting in '-' through untouched. This fixes the ordering of the check to recognize '-' flags first in case the rest of the option looks like a library file name, as in the case of "-l:libfoo.a".
* BUG: Do not recognize ':' in a library nameBrad King2009-07-281-1/+1
| | | | | | In cmComputeLinkInformation we construct regular expressions to recognize library file names. This fixes the expressions to not allow a colon (':') in the file name so that "-l:libfoo.a" is left alone.
* ENH: Link runtime libraries of all languagesBrad King2009-07-271-0/+69
| | | | | | | | | | | | | | | | | | This adds implicit libraries and search directories for languages linked into a target other than the linker language to its link line. For example, when linking an executable containing both C++ and Fortran code the C++ linker is used but we need to add the Fortran libraries. The variables CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES contain the implicit libraries and directories for each language. Entries for the linker language are known to be implicit in the generated link line. Entries for other languages that do not appear in the known implicit set are listed explicitly at the end of the link line.
* STYLE: Factor cmComputeLinkInformation constructorBrad King2009-07-141-15/+24
| | | | | This factors some code out of the constructor into a new method cmComputeLinkInformation::LoadImplicitLinkInfo for readability.
* ENH: Pass config to cmTarget::GetLinkerLanguageBrad King2009-07-081-1/+1
| | | | | | This passes the build configuration to most GetLinkerLanguage calls. In the future the linker language will account for targets linked in each configuration.
* ENH: Pass config to cmTarget RPATH install methodsBrad King2009-07-081-1/+1
| | | | | This passes the build configuration to cmTarget methods IsChrpathUsed and NeedRelinkBeforeInstall. Later these methods will use the value.
* ENH: Simpler cmTarget::GetLinkerLanguage signatureBrad King2009-07-071-2/+1
| | | | | | | 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.
* BUG: Do not create empty build-tree RPATHBrad King2009-06-111-4/+7
| | | | | | | | The fix for issue #9130 appends ':' to the end of the build-tree RPATH unconditionally. This changes the fix to add ':' only when the RPATH is not empty so that we do not create a build-tree RPATH with just ':'. An empty RPATH produces no string at all, so there is no chance of merging with a symbol name anyway.
* BUG: Do not mangle symbols when editing RPATHsBrad King2009-06-101-2/+7
| | | | | | | | | | | | | In ELF binaries the .dynstr string table is used both for the RPATH string and for program symbols. If a symbol name happens to match the end of the build-tree RPATH string the linker is allowed to merge the symbols. We must not allow this when the RPATH string will be replaced during installation because it will mangle the symbol. Therefore we always pad the end of the build-tree RPATH with ':' if it will be replaced. Tools tend not to use ':' at the end of symbol names, so it is unlikely to conflict. See issue #9130.
* BUG: Recognize .so shared libraries on HP-UXBrad King2009-06-031-0/+11
| | | | | | HP-UX uses both .sl and .so as extensions for shared libraries. This teaches CMake to recognize .so shared libraries so they are treated properly during link dependency analysis.
* ENH: Keep target information in final link lineBrad King2008-09-151-2/+2
| | | | | | | In cmComputeLinkInformation items in the final link line returned by GetItems now contain a pointer to their corresponding cmTarget if they were produced by a target. This makes available the set of all targets linked.
* ENH: Add UNKNOWN type for IMPORTED librariesBrad King2008-08-181-4/+9
| | | | | | | | | | | | | | | 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.
* BUG: Preserve all non-targets on user link linesBrad King2008-07-301-1/+0
| | | | | | | | | | | | | | | | | | | | | In CMake 2.4 the generated link line for a target always preserved the originally specified libraries in their original order. Dependencies were satisfied by inserting extra libraries into the line, though it had some bugs. In CMake 2.6.0 we preserved only the items on the link line that are not known to be shared libraries. This reduced excess libraries on the link line. However, since we link to system libraries (such as /usr/lib/libm.so) by asking the linker to search (-lm), some linkers secretly replace the library with a static library in another implicit search directory (developers can override this by using an imported target to force linking by full path). When this happens the order still matters. To avoid this and other potential subtle issues this commit restores preservation of all non-target items and static library targets. This will create cases of unnecessary, duplicate shared libraries on the link line if the user specifies them, but at least it will work. In the future we can attempt a more advanced analysis to safely remove duplicate shared libraries from the link line.
* ENH: Warn when system libraries may be hidden.Brad King2008-07-291-0/+4
| | | | | | | | We never explicitly specify system library directories in linker or runtime search paths. Furthermore, libraries in these directories are always linked by asking the linker to search for them. We need to generate a warning when explicitly specified search directories contain files that may hide the system libraries during the search.

* ENH: Support full-path libs w/out valid names.Brad King2008-07-231-40/+68
| | | | | | | | 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.
* ENH: Skip libs in known dirs for CMP0003 warnings.Brad King2008-07-231-5/+9
| | | | | | | Sometimes we ask the linker to search for a library for which the path is known but for some reason cannot be specified by full path. In these cases do not include the library in CMP0003 warnings because we know the extra paths are not needed for it.
* ENH: Support full-path libs w/out extension in VS IDE.Brad King2008-07-211-1/+40
| | | | | | | - This case worked accidentally in CMake 2.4, though not in Makefiles. - Some projects build only with the VS IDE on windows and have this mistake. - Support them when 2.4 compatibility is enabled by adding the extension.
* ENH: When preserving potentially static portions of original user link lines ↵Brad King2008-04-301-1/+4

| | | | | | | | | | | | - 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
* BUG: Fix bug 6605 more completelyBrad King2008-03-311-0/+20
| | | | | | - CMake 2.4 added link directories for targets linked in the optimized configuration even when building debug - Old behavior for policy CMP0003 must account for this
* ENH: Yet another attempt at warning for CMP0003.Brad King2008-03-211-50/+37
| | | | | | | - 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

* ENH: Improve CMP0003 to provide more compatibilityBrad King2008-03-141-3/+17
| | | | | | | - Targets built in the tree now add compatibility paths too - The warning message's first list includes at most one item for each unique compatibility path - Clarified error message further
* ENH: Convert CMAKE_LINK_OLD_PATHS to policy CMP0003.Brad King2008-03-131-18/+123
| | | | | | | | | - 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
* ENH: Cleanup builtin chrpath supportBrad King2008-03-021-0/+12
| | | | | | | | | | | | - Move computation of extended build-tree rpath to cmComputeLinkInformation - Only enable the extended build-tree rpath if the target will be installed - Generalize the interface of file(CHRPATH) - When changing the rpath on installation only replace the part generated by CMake because the native tools (ex SunCC on Linux) might have added their own part to the rpath
* ENH: Use builtin chrpath instead of relinking ELF targetsBrad King2008-03-011-6/+0
| | | | | | | | | | - 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
* BUG: cmComputeLinkInformation::CheckImplicitDirItem needs to extract the ↵Brad King2008-02-291-2/+2

* ENH: Improve linking to third-party shared libraries on soname platformsBrad King2008-02-211-5/+20
| | | | | | | | | | | | | | - Reduce false positives in cases of unknown soname - Make library extension regular expressions match only at end of string - When linking to libraries in implicit dirs convert to the -l option only if the file name is one that can be found by the linker (ex. /usr/lib/libfoo.so.1 should be linked by full path) - Add cmSystemTools::GuessLibrarySOName to guess the soname of a library based on presence of a symlink - In cmComputeLinkInformation try to guess an soname before assuming that a third-party library is built without an soname - In cmOrderDirectories guess the soname of shared libraries in cases it is otherwise unknown
* ENH: Better linker search path computation.Brad King2008-02-211-75/+149
| | | | | | | | | | | | | - 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
* BUG: Fix cmComputeLinkInformation to include the target's user link ↵Brad King2008-02-071-0/+5
