All generators now support detection of the full path to the compiler, so require it to be so. This will allow CMake<LANG>Information.cmake and other logic to assume the full path to the compiler tool is available. The Makefile generators already rejected CMAKE_<LANG>_COMPILER values that did not name an existing compiler. Extend this error message to all generators, make it occur as early as possible, and improve the message with advice about how to set the compiler. If the full path to the compiler is not known, finish enabling languages with a fatal error so configuration does not continue. For now, allow the RC language compiler to not be a full path. Later we will need to detect the full path to "rc" under the VS IDE. Add a RunCMake.CompilerNotFound test to cover failure cases. Fix the RunCMake.CompilerChange test EmptyCompiler case to work when configuration does not continue past enable_language.
This is CMake, the cross-platform, open-source make system. CMake is distributed under the BSD License, see Copyright.txt. For documentation see the Docs/ directory once you have built CMake or visit http://www.cmake.org. 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 shouldn't be a major problem to port CMake to this platform. Contact the CMake mailing list in this case: http://www.cmake.org/mailman/listinfo/cmake If you don't have any previous version of CMake already installed -------------------------------------------------------------- * 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 want to 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. So basically it's the same as you may be used to from autotools-based projects: $ ./bootstrap; make; make install * Other Windows: You need to download and install a binary release of CMake in order to build CMake. You can get these releases from http://www.cmake.org/HTML/Download.html . Then proceed with the instructions below. You already have a version of CMake installed --------------------------------------------- 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 http://www.cmake.org/HTML/RunningCMake.html
