1Installation instructions for Eigen 2*********************************** 3 4Explanation before starting 5*************************** 6 7Eigen consists only of header files, hence there is nothing to compile 8before you can use it. Moreover, these header files do not depend on your 9platform, they are the same for everybody. 10 11Method 1. Installing without using CMake 12**************************************** 13 14You can use right away the headers in the Eigen/ subdirectory. In order 15to install, just copy this Eigen/ subdirectory to your favorite location. 16If you also want the unsupported features, copy the unsupported/ 17subdirectory too. 18 19Method 2. Installing using CMake 20******************************** 21 22Let's call this directory 'source_dir' (where this INSTALL file is). 23Before starting, create another directory which we will call 'build_dir'. 24 25Do: 26 27 cd build_dir 28 cmake source_dir 29 make install 30 31The "make install" step may require administrator privileges. 32 33You can adjust the installation destination (the "prefix") 34by passing the -DCMAKE_INSTALL_PREFIX=myprefix option to cmake, as is 35explained in the message that cmake prints at the end. 36
