| 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. |
