* Refactor generation of shared library flagsStephen Kelly2012-06-121-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | CMAKE_SHARED_LIBRARY_<lang>_FLAGS has flags on various platforms for a variety of purposes that are correlated with shared libraries but not exclusive to them. Refactor generation of these flags to use new purpose-specific platform variables CMAKE_<lang>_COMPILE_OPTIONS_DLL CMAKE_<lang>_COMPILE_OPTIONS_PIC CMAKE_<lang>_COMPILE_OPTIONS_PIE Activate the DLL flags specifically for shared libraries. Add a new POSITION_INDEPENDENT_CODE target property to activate PIC/PIE flags, and default to true for shared libraries to preserve default behavior. Initialize the new property from CMAKE_POSITION_INDEPENDENT_CODE to allow easy global configuration in projects. Although the default behavior is unchanged by this refactoring, the new approach ignores CMAKE_SHARED_LIBRARY_<lang>_FLAGS completely. We must leave it set in case projects reference the value. Furthermore, if a project modifies CMAKE_SHARED_LIBRARY_<lang>_FLAGS it expects the new value to be used. Add policy CMP0018 to handle compatibility with projects that modify this platform variable. Add a PositionIndependentCode test on platforms where we can get meaningful results.

| * Use CPACK_xxx and CMAKE_xxx in a consistent way.Eric NOULARD2012-05-201-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CMAKE_xxx vars are now used in the CMake-generated cmake_install.cmake script while CPACK_xxx equivalent vars are used from within CPack. CPack is responsible for getting/forwarding definitions of CPACK_xxxx var corresponding to CMAKE_xxxx when invoking CMake-generated install scripts. As a consequence: CMAKE_ABSOLUTE_DESTINATION_FILES CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION may be used from outside CPack as well. e.g. cmake -DCMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION=1 -P cmake_install.cmake works as expected.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach CMakePlatformId.h to construct an "INFO:compiler_version[]" string literal from macros COMPILER_VERSION_(MAJOR|MINOR|PATCH|TWEAK) to be defined in CMake(C|CXX)CompilerId.(c|cpp) for each compiler. Provide conversion macros DEC() and HEX() to decode decimal or hex digits from integer values. Parse the version out of the compiler id binary along with the other INFO values already present. Store the result in variable CMAKE_<LANG>_COMPILER_VERSION in the format "major[.minor[.patch[.tweak]]]". Save the value persistently in CMake(C|CXX)Compiler.cmake in the build tree. Document the variable for internal use since we do not set it everywhere yet. Report the compiler version on the compiler id result line e.g. The C compiler identification is GNU 4.5.2 Report CMAKE_(C|CXX)_COMPILER_(ID|VERSION) in SystemInformation test.

Add an extra step to the link command for shared libraries and executables that export symbols and on which a new GNUtoMS property is set (initialized by the CMAKE_GNUtoMS option). Tell the GNU linker to output a module definition (.def) file listing exported symbols in addition to the GNU-format import library (.dll.a). Pass the .def file to the MS "lib" tool to construct a MS-format DLL import library (.lib). Teach the install(TARGETS) command to install the MS import library next to the GNU one. Teach the install(EXPORT) and export() command to set the IMPORTED_IMPLIB property pointing at the import library to use the import library matching the tools in the importing project.

| * | New version scheme to support branchy workflowBrad King2010-04-231-3/+11

In this workflow, the "master" branch is always used to integrate topics ready for release. Brand new work merges into a "next" branch instead. We need a new versioning scheme to work this way because the version on "master" must always increase. We no longer use an even/odd minor number to distinguish releases from development versions. Since we still support cvs checkout of our source tree we cannot depend on "git describe" to compute a version number based on the history graph. We can use the CCYYMMDD nightly date stamp to get a monotonically increasing version component. The new version format is "major.minor.patch.(tweak|date)". Releases use a tweak level in the half-open range [0,20000000), which is smaller than any current or future date. For tweak=0 we do not show the tweak component, leaving the format "major.minor.patch" for most releases. Development versions use date=CCYYMMDD for the tweak level. The major.minor.patch part of development versions on "master" always matches the most recent release. For example, a first-parent traversal of "master" might see v2.8.1 2.8.1.20100422 v2.8.2 | | | ----o----o----o----o----o----o----o----o---- Since the date appears in the tweak component, the next release can increment the patch level (or any more significant component) to be greater than any version leading to it. Topic branches not ready for release are published only on "next" so we know that all versions on master lead between two releases.
