The archive contains only the following files: QuantLib-1.2-cmake/CMakeLists.txt # the main cmake file: provides the options and builds the library QuantLib-1.2-cmake/files.cmake # the list of source files in ql/ QuantLib-1.2-cmake/config.cmake # process the user options and creates ql/config.hpp QuantLib-1.2-cmake/ql/config.hpp.cmake # the input to obtain ql/config.hpp QuantLib-1.2-cmake/Examples/CMakeLists.txt # deals with examples QuantLib-1.2-cmake/test-suite/CMakeLists.txt # deals with the test suite QuantLib-1.2-cmake/test-suite/files.cmake # the list of source files in the test suite QuantLib-1.2-cmake/test-suite/main.cpp # see below To get things ready to roll, you need first to put the files in the archive into a clean QuantLib source tree: # untar the archive in a place of your choice cd /path/to ; tar xvfz QuantLib-1.2-cmake.tar.gz # copy its contents into your fresh & clean QuantLib folder: cd /to/your/QuantLib-1.2 ; cp -r /path/to/QuantLib-1.2-cmake/* . Instructions for a console build & install. I presume most of you are already familiar with usage of cmake, but I'll outline the procedure just in case. # configure & build (out of source) cd /to/your/QuantLib-1.2/build cmake -DCMAKE_INSTALL_PREFIX=/your/install/folder .. # note the path to the location of the main CMakeLists.txt make # install make install I've setup the options so that defaults are the same as in autotools. So the above procedure won't compile examples or benchmarks. To get that, you can either use the command line or a GUI. Using the command line, the cmake command becomes cmake -DCMAKE_INSTALL_PREFIX=/your/install/folder -DQuantLib_WITH_EXAMPLES -DQuantLib_WITH_BENCHMARK .. with all the rest being equal. Each -D above is the definition of the value of a cmake option. If, for example, you want to disable deprecated code, set the value of the option QuantLib_ENABLE_DEPRECATED_CODE to OFF using . cmake -DCMAKE_INSTALL_PREFIX=/your/install/folder -DQuantLib_WITH_EXAMPLES -DQuantLib_WITH_BENCHMARK -DQuantLib_ENABLE_DEPRECATED_CODE=OFF .. Since it can be bothersome to remember all the names for these options, the cmake GUI can be handy. For the GUI, there are two choices: a curses-based console GUI (ccmake in ubuntu) and a Qt-based GUI (cmake-gui). I'll start with the curses GUI. The cmake command now can simply be instead: ccmake .. Now you'll be able to see and edit the available options, following the instructions at the bottom of the screen. Basically, the procedure consists of iterating between setting an option (or options) and pressing 'c' to configure - until nothing changes (please note that some options activate other options). Then hit 'g' to generate the Makefiles, and exit. The procedure is exactly the same for the Qt GUI, only now you must use the mouse to carry it out. CAVEAT: There are currently two places which raise issues of compatibility of cmake with autotools (which I hope you'll help me fix): - the obtaining of ql/config.hpp . Currently I've added ql/config.hpp.cmake which is processed into config.hpp . This is done from the file config.cmake . As it stands, this is not actually incompatible, but it will always require sync between changes to any input config.hpp. - in the test suite, autotools creates automatically a main.cpp. It was not easy for me to see the reason for this, so I've put it statically in the test folder. It is because of these caveats that I started above by advising use of a clean QuantLib tree. Nevertheless, I was able to have a tree with both build systems working. OK - done for now. Please tell me what you think of this.
