| * Refactor generation of shared library flagsStephen Kelly2012-06-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Factor out custom command .rule file path generationBrad King2012-04-181-0/+3
| | | | | | | Add cmGlobalGenerator::GenerateRuleFile to compute a generator-specific rule file location. This will allow specific generators to override the location of .rule files without changing the behavior of other generators.
* Rename/constify build-time config placeholder lookupBrad King2012-03-091-1/+1
| | | | | | Rename cmGlobalGenerator::GetCMakeCFG{InitDirectory => IntDir} to have a shorter name without a typo. Add a 'const' qualifier since the method is only for lookup and never needs to modify anything.
* Pre-compute object file names before Makefile generationBrad King2012-03-091-0/+1
| | | | | | | Add a virtual cmGlobalGenerator::ComputeTargetObjects method invoked during cmGeneratorTarget construction. Implement it in the Makefile generator to pre-compute all object file names for each target. Use the results during generation instead of re-computing it later.
* Create a cmGeneratorTarget for each cmTarget during generationBrad King2012-03-091-0/+10
| | | | | | | Construct the instances after the final set of targets is known but before computing inter-target dependencies. This order will allow initialization of cmGeneratorTarget instances to adjust and finalize declared inter-target dependencies.
* Optionally allow IMPORTED targets to be globally visibleBrad King2012-01-251-1/+2
| | | | | | | | | | | | Consider the case motivating commit e01cce28 (Allow add_dependencies() on imported targets, 2010-11-19). An imported target references a file generated at build time by a custom target on which it depends. Had the file been built directly using add_library or add_executable its target name would have been visible globally. Therefore the imported target representing the file should be globally visible also. Teach the IMPORTED signature of add_(executable|library) to accept a new "GLOBAL" option to make the imported target visible globally.

| * try_compile: Allow only languages loaded in caller (#11469)Brad King2011-01-241-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | During a try_compile cmGlobalGenerator::EnableLanguage uses results from the outer project. Reject attempts to enable languages in the test project that are not "ready" in the outer project. Mark a language as "ready" when all its information has been loaded and we are ready to generate build rules. This also avoids infinite recursion introduced by commit 295b5b60 (Honor CMAKE_USER_MAKE_RULES_OVERRIDE in try_compile, 2010-06-29) for projects that set CMAKE_USER_MAKE_RULES_OVERRIDE to a file that uses try_compile. The file is loaded along with the information for a given langauge so the language is not yet "ready".
* | Remove unused GLOBAL_TARGET generation codeBrad King2010-12-131-2/+1
| | | | | | | | | | | | Remove a boolean parameter of cmGlobalGenerator::CreateGlobalTarget that is never set to true anymore. Remove global target "consolidation" loop because no global targets exist before it runs anymore.

| * | Add FOLDER target property, for IDEs (#3796)David Cole2010-09-031-0/+3
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This work was started from a patch by Thomas Schiffer. Thanks, Thomas! See the newly added documentation of the FOLDER target property for details. Also added global properties, USE_FOLDERS and PREDEFINED_TARGETS_FOLDER. See new docs here, too. By default, the FOLDER target property is used to organize targets into folders in IDEs that have support for such organization. This commit adds "solution folder" support to the Visual Studio generators. Currently works with versions 7 through 10. Also, use the new FOLDER property in the ExternalProject test and in the CMake project itself.

* Fix rule hash persistence file generationBrad King2010-02-121-0/+2
| | | | | | | | | | | | | | | | | | | | | We store custom command rule hashes in CMakeFiles/CMakeRuleHashes.txt persistently across CMake runs. When the rule hash changes we delete the custom command output file and write a new hash into the persistence file. This functionality was first added by the commit 'Introduce "rule hashes" to help rebuild files when rules change.' (2008-06-02). However, the implementation in cmGlobalGenerator::CheckRuleHashes kept the file open for read when attempting to rewrite a new file. On Windows filesystems this prevented the new version of the file from being written! This caused the first set of rule hashes to be used forever within a build tree, meaning that all custom commands whose rules changed would be rebuilt every time CMake regenerated the build tree. In this commit we address the problem by splitting the read and write operations into separate methods. This ensures that the input stream is closed before the output stream opens the file.
* Fix issue #2336 - honor the -C arg to ctest. Honor it for all stages of ↵David Cole2009-12-041-0/+4
| | | | running -D dashboards from the command line and running ctest_configure, ctest_build and ctest_test commands in -S scripts. Also, allow a script to change it by setting the CTEST_CONFIGURATION_TYPE variable: allows for multiple configuration build/test cycles within one script. Add a new signature for the cmake command build_command that accepts CONFIGURATION as one argument. The original build_command signature is still there, but now marked as deprecated in the documentation. Of course... also add CTestConfig tests to verify that -C is honored for -D dashboards and -S scripts.
* Avoid non-root copies of root-only targetsBrad King2009-10-061-0/+1
| | | | | | | | | | | | | | In cmGlobalGenerator::GetTargetSets we collect targets from all local generators in a tree or subtree corresponding to a project() command. Some targets, such as ALL_BUILD, are duplicated in each subdirectory with a project() command. For such targets we should keep only the copy for the top-most (root) local generator. Previously this filtering was done in each VS IDE generator, but it is easier to do it in one place when the targets are first encountered. This also fixes bad ALL_BUILD dependencies generated for VS 7.0 because the cmGlobalVisualStudio7Generator::WriteTargetDepends method was not filtering out duplicates. Now we avoid duplicates from the start.
* Cleanup cmGlobalGenerator::GetTargetSets methodBrad King2009-10-011-7/+5
| | | | | | This commit cleans up the declaration, definition, and invocations of the GetTargetSets method and related code. There is no change in function except to make the method virtual.
* 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.
* No /fast targets in try_compile project modeBrad King2009-08-041-1/+1
| | | | | | | | The try_compile command builds the cmTryCompileExec executable using the cmTryCompileExec/fast target with Makefile generators in order to save time since dependencies are not needed. However, in project mode the command builds an entire source tree that may have dependencies. Therefore we can use the /fast target approach only in one-source mode.
* Fix recursive try_compile callsBrad King2009-08-031-1/+1
| | | | | | | | When building an entire source tree with try_compile instead of just a single source file, it is possible that the CMakeLists.txt file in the try-compiled project invokes try_compile. This commit fixes propagation of language-initialization results from the outer-most project into any number of try-compile levels.

* BUG: Fix Xcode linker languageBrad King2009-07-101-3/+3
| | | | | | | | | | Xcode does not seem to support direct requests for using the linker for a particular language. It always infers the linker using the languages in the source files. When no user source files compile with target's linker language we add one to help Xcode pick the linker. A typical use case is when a C executable links to a C++ archive. The executable has no C++ source files but we need to use the C++ linker.
* ENH: Generate a central list of target directoriesBrad King2009-03-091-2/+2
| | | | | | | | This generalizes the previous CMakeFiles/LabelFiles.txt created at the top of the build tree to a CMakeFiles/TargetDirectories.txt file. It lists the target support directories for all targets in the project. Labels can still be loaded by looking for Labels.txt files in each target directory.
* ENH: Extend GG::Build method for pre-parsed argsBrad King2009-03-041-7/+9
| | | | | This adds an argument to the cmGlobalGenerator::Build method to pass a vector of arguments for the native build tool programatically.
* ENH: Enforce unique binary directoriesBrad King2009-02-271-0/+9
| | | | | | The second argument of add_subdirectory must name a unique binary directory or the build files will clobber each other. This enforces uniqueness with an error message.
* ENH: Define target and source property LABELSBrad King2009-02-101-0/+3
| | | | | | This creates a new LABELS property for targets and source files. We write the labels of each target and its source files in target-specific locations in the build tree for future use.
* ENH: Refactor custom command rule hashingBrad King2009-02-021-2/+1
| | | | | | | | | | This simplifies computation of custom command rule hashes to hash content exactly chosen as the custom commands are generated. Unfortunately this will change the hashes of existing build trees from earlier CMake versions, but this is not a big deal. The change is necessary so that in the future we can make optional adjustments to custom command lines at generate time without changing the hashes every time the option is changed.

* ENH: Make dir content cache work during configureBrad King2008-09-221-5/+5
| | | | | | Previously the cmGlobalGenerator::GetDirectoryContent method would work safely only during build system generation. These changes make it safe to use during each configure step by flushing it at the beginning.
* BUG: Fix try_compile during EnableLanguageBrad King2008-07-161-0/+1
| | | | | | | | | | | | | | - The source-file signature of try_compile looks up the language of the source file using the extension-to-language map so that it knows what language to enable in the generated project. - This map needs to be filled before loading a file specified by CMAKE_USER_MAKE_RULES_OVERRIDE CMAKE_USER_MAKE_RULES_OVERRIDE_<LANG> so that the user file may call the try_compile() source-file signature. - It must still be re-filled after loading CMake<LANG>Information.cmake in case the compiler- or platform-specific files added anything. - See bug #7340.
* ENH: Further refinement of the CPack components functionality from Doug Gregor.David Cole2008-07-081-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Details: ========== - New cpack_add_component, cpack_add_component_group, and cpack_add_install_type "commands" defined as macros in the CPack module. - Documentation for all of the variables and commands in the CPack module. - Added get_cmake_property(... COMPONENTS) to CMake to ask for the names of all components. Used in the CPack module to automatically build component-based installers. (Set CPACK_MONOLITHIC_INSTALL to turn off component-based installation). - A group can declare its PARENT_GROUP, to build an arbitrary hierarchy of groups. - New CPack command cpack_configure_downloads, which creates an installer that downloads only the selected components on-the-fly. Those components marked DOWNLOADED will be separate packages downloaded on-the-fly (or, all packages can be marked as such with the ALL option to cpack_configure_downloads). Individual components are compressed with ZIP at installer-creation time and downloaded/uncompressed by the installer as needed. This feature is only available on Windows with NSIS at the moment. - NSIS installers can install themselves and enable the "Change" button in Add/Remove programs, allowing users to go back and install or remove components. This can be disabled through cpack_configure_downloads, because it's only really useful is most of the application's functionality is in downloaded components. - Bug fix: automatically install everything whose COMPONENT was not specified (it's a hidden, required group) - Bug fix: fixed removal of components when re-running the NSIS installer and unchecking components - Bug fix: NSIS installers now only install/remove the minimal number of files when re-run to update the installation (or by clicking "Change" in Add/Remove programs)
* BUG: Include less content as input to "rule hash" computation.Brad King2008-06-031-2/+2
| | | | | | | - The rule hash should use only commands specified by the user. - No make output (echo and progress) rules should be included. - No outputs or dependencies need be included. The native build tool will take care of them.
* ENH: Introduce "rule hashes" to help rebuild files when rules change.Brad King2008-06-021-0/+9
| | | | | | | | | | | | | | - In CMake 2.4 custom commands would not rebuild when rules changed. - In CMake 2.6.0 custom commands have a dependency on build.make which causes them to rebuild when changed, but also when any source is added or removed. This is too often. - We cannot have a per-rule file because Windows filesystems do not deal well with lots of small files. - Instead we add a persistent CMakeFiles/CMakeRuleHashes.txt file at the top of the build tree that is updated during each CMake Generate step. It records a hash of the build rule for each file to be built. When the hash changes the file is removed so that it will be rebuilt.
* BUG: Fix crash on repeated configure steps and exported targets.Brad King2008-05-271-0/+1
| | | | | | - In cmGlobalGenerator the ExportSets ivar must be cleared at the beginning of each Configure. - See issue #7101.
* BUG: Make sure all source files are found before generating.Brad King2008-05-121-0/+2
| | | | | | | | - 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.
