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