| Explanation before starting |
| *************************** |
| |
| Eigen consists only of header files, hence there is nothing to compile |
| before you can use it. Moreover, these header files do not depend on your |
| platform, they are the same for everybody. |
| |
| Method 1. Installing without using CMake |
| **************************************** |
| |
| You can use right away the headers in the Eigen/ subdirectory. In order |
| to install, just copy this Eigen/ subdirectory to your favorite location. |
| If you also want the unsupported features, copy the unsupported/ |
| subdirectory too. |
| |
| Method 2. Installing using CMake |
| ******************************** |
| |
| Let's call this directory 'source_dir' (where this INSTALL file is). |
| Before starting, create another directory which we will call 'build_dir'. |
| |
| Do: |
| |
| cd build_dir |
| cmake source_dir |
| make install |
| |
| The "make install" step may require administrator privileges. |
| |
| You can adjust the installation destination (the "prefix") |
| by passing the -DCMAKE_INSTALL_PREFIX=myprefix option to cmake, as is |
| explained in the message that cmake prints at the end. |
