Commit v3.0.0-rc1~111^2 (QNX: Introduce QCC compiler id for that QNX platform compiler., 2014-01-20) split handling of the QNX QCC compiler into a separate compiler-id. That refactoring results in the QCC compiler not using the CMake-compiler-id "GNU", which means that the __compiler_gnu macro is no longer executed for it. Add Compiler/QCC*.cmake modules to define and call the __compiler_qcc macro and teach it to call __compiler_gnu internally. Remove the corresponding pieces from the Platform/QNX*.cmake modules. It is also necessary to change the language conditional to dereference the lang macro parameter, which is another bug introduced by the same commit. The extra -lang-c++ flag is only necessary when the CXX compiler is specified as 'qcc' instead of 'QCC' in the toolchain file, which is why this bug was not noticed before. The flag is also necessary in that case when linking in order to find the appropriate standard libraries. The flag was not previously added when linking executables, so linking failed even with CMake 2.8.12 with the lower-case compiler-id. Co-Author: Brad King <brad.king@kitware.com>
CMake ***** Introduction ============ CMake is a cross-platform, open-source build system generator. For full documentation visit the `CMake Home Page`_ and the `CMake Documentation Page`_. .. _`CMake Home Page`: http://www.cmake.org .. _`CMake Documentation Page`: http://www.cmake.org/cmake/help/documentation.html CMake is maintained and supported by `Kitware`_ and developed in collaboration with a productive community of contributors. .. _`Kitware`: http://www.kitware.com/cmake License ======= CMake is distributed under the OSI-approved BSD 3-clause License. See `Copyright.txt`_ for details. .. _`Copyright.txt`: Copyright.txt Building CMake ============== Supported Platforms ------------------- MS Windows, Mac OS X, Linux, FreeBSD, Solaris, HP-UX, IRIX, BeOS, QNX Other UNIX-like operating systems may work too out of the box, if not it should not be a major problem to port CMake to this platform. Subscribe and post to the `CMake Users List`_ to ask if others have had experience with the platform. .. _`CMake Users List`: http://www.cmake.org/mailman/listinfo/cmake Building CMake from Scratch --------------------------- UNIX/Mac OSX/MinGW/MSYS/Cygwin ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ You need to have a compiler and a make installed. Run the ``bootstrap`` script you find the in the source directory of CMake. You can use the ``--help`` option to see the supported options. You may use the ``--prefix=<install_prefix>`` option to specify a custom installation directory for CMake. You can run the ``bootstrap`` script from within the CMake source directory or any other build directory of your choice. Once this has finished successfully, run ``make`` and ``make install``. In summary:: $ ./bootstrap && make && make install Windows ^^^^^^^ You need to download and install a binary release of CMake in order to build CMake. You can get these releases from the `CMake Download Page`_ . Then proceed with the instructions below. .. _`CMake Download Page`: http://www.cmake.org/cmake/resources/software.html Building CMake with CMake ------------------------- You can build CMake as any other project with a CMake-based build system: run the installed CMake on the sources of this CMake with your preferred options and generators. Then build it and install it. For instructions how to do this, see documentation on `Running CMake`_. .. _`Running CMake`: http://www.cmake.org/cmake/help/runningcmake.html Contributing ============ See `CONTRIBUTING.rst`_ for instructions to contribute. .. _`CONTRIBUTING.rst`: CONTRIBUTING.rst
