| Narayan Kamath | c981c48 | 2012-11-02 10:59:05 +0000 | [diff] [blame] | 11 | If you want to guarantee that the Eigen code that you are #including is licensed |
| 12 | under the MPL2 and possibly more permissive licenses (like BSD), #define this |
| 13 | preprocessor symbol: |
| 14 | EIGEN_MPL2_ONLY |
| 15 | For example, with most compilers, you could add this to your project CXXFLAGS: |
| 16 | -DEIGEN_MPL2_ONLY |
| 17 | This will cause a compilation error to be generated if you #include any code that is |
| 18 | LGPL licensed. |
