| MADlib builds Eigen using the EIGEN_MPL2_ONLY flag enabled. |
| |
| From the Eigen Licensing page |
| (http://eigen.tuxfamily.org/index.php?title=Main_Page) |
| |
| Eigen is Free Software. Starting from the 3.1.1 version, it is licensed |
| under the MPL2, which is a simple weak copyleft license. Common |
| questions about the MPL2 are answered in the official MPL2 FAQ |
| (http://www.mozilla.org/MPL/2.0/FAQ.html). |
| |
| Note that currently, a few features rely on third-party code licensed |
| under the LGPL: SimplicialCholesky, AMD ordering, and constrained_cg. |
| Such features can be explicitly disabled by compiling with the |
| EIGEN_MPL2_ONLY preprocessor symbol defined. |
| |
| Virtually any software may use Eigen. For example, closed-source |
| software may use Eigen without having to disclose its own source code. |
| Many proprietary and closed-source software projects are using Eigen |
| right now, as well as many BSD-licensed projects. |

| |
| Each Contributor hereby grants You a world-wide, royalty-free, |
| non-exclusive license: |
| |
| • under intellectual property rights (other than patent or trademark) |
| Licensable by such Contributor to use, reproduce, make available, |
| modify, display, perform, distribute, and otherwise exploit its |
| Contributions, either on an unmodified basis, with Modifications, or as |

| |
| 2.2. Effective Date |
| |
| The licenses granted in Section 2.1 with respect to any Contribution |
| become effective for each Contribution on the date the Contributor |
| first distributes such Contribution. |
| |
| 2.3. Limitations on Grant Scope |
| |
| The licenses granted in this Section 2 are the only rights granted |
| under this License. No additional rights or licenses will be implied |
| from the distribution or licensing of Covered Software under this |
| License. Notwithstanding Section 2.1(b) above, no patent license is |
| granted by a Contributor: |
| |
| • for any code that a Contributor has removed from Covered Software; |
| or |
| |
| • for infringements caused by: (i) Your and any other third party’s |
| modifications of Covered Software, or (ii) the combination of its |
| Contributions with other software (except as part of its Contributor |
| Version); or |
| |
| • under Patent Claims infringed by Covered Software in the absence of |
| its Contributions. |
| |
| This License does not grant any rights in the trademarks, service |
| marks, or logos of any Contributor (except as may be necessary to |
| comply with the notice requirements in Section 3.4). |
| |
| 2.4. Subsequent Licenses |
| |
| No Contributor makes additional grants as a result of Your choice to |
| distribute the Covered Software under a subsequent version of this |
| License (see Section 10.2) or under the terms of a Secondary License |
| (if permitted under the terms of Section 3.3). |
| |
| 2.5. Representation |
| |
| Each Contributor represents that the Contributor believes its |
| Contributions are its original creation(s) or it has sufficient rights |
| to grant the rights to its Contributions conveyed by this License. |
| |
| 2.6. Fair Use |
| |
| This License is not intended to limit any rights You have under |
| applicable copyright doctrines of fair use, fair dealing, or other |
| equivalents. |
| |
| 2.7. Conditions |
| |
| Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted |
| in Section 2.1. |
| |
| 3. Responsibilities |
| |
| 3.1. Distribution of Source Form |
| |
| All distribution of Covered Software in Source Code Form, including any |
| Modifications that You create or to which You contribute, must be under |
| the terms of this License. You must inform recipients that the Source |
| Code Form of the Covered Software is governed by the terms of this |
| License, and how they can obtain a copy of this License. You may not |
| attempt to alter or restrict the recipients’ rights in the Source Code |
| Form. |
| |
| 3.2. Distribution of Executable Form |
| |
| If You distribute Covered Software in Executable Form then: |
| |
| • such Covered Software must also be made available in Source Code |
| Form, as described in Section 3.1, and You must inform recipients of |
| the Executable Form how they can obtain a copy of such Source Code Form |
| by reasonable means in a timely manner, at a charge no more than the |
| cost of distribution to the recipient; and |
| |
| • You may distribute such Executable Form under the terms of this |
| License, or sublicense it under different terms, provided that the |
| license for the Executable Form does not attempt to limit or alter the |
| recipients’ rights in the Source Code Form under this License. |
| |
| 3.3. Distribution of a Larger Work |
| |
| You may create and distribute a Larger Work under terms of Your choice, |
| provided that You also comply with the requirements of this License for |
| the Covered Software. If the Larger Work is a combination of Covered |
| Software with a work governed by one or more Secondary Licenses, and |
| the Covered Software is not Incompatible With Secondary Licenses, this |
| License permits You to additionally distribute such Covered Software |
| under the terms of such Secondary License(s), so that the recipient of |
| the Larger Work may, at their option, further distribute the Covered |
| Software under the terms of either this License or such Secondary |
| License(s). |
| |
| 3.4. Notices |
| |
| You may not remove or alter the substance of any license notices |
| (including copyright notices, patent notices, disclaimers of warranty, |
| or limitations of liability) contained within the Source Code Form of |
| the Covered Software, except that You may alter any license notices to |
| the extent required to remedy known factual inaccuracies. |
| |
| 3.5. Application of Additional Terms |
| |
| You may choose to offer, and to charge a fee for, warranty, support, |
| indemnity or liability obligations to one or more recipients of Covered |
| Software. However, You may do so only on Your own behalf, and not on |
| behalf of any Contributor. You must make it absolutely clear that any |
| such warranty, support, indemnity, or liability obligation is offered |
| by You alone, and You hereby agree to indemnify every Contributor for |
| any liability incurred by such Contributor as a result of warranty, |
| support, indemnity or liability terms You offer. You may include |
| additional disclaimers of warranty and limitations of liability |
| specific to any jurisdiction. |
| |
| 4. Inability to Comply Due to Statute or Regulation |
| |
| If it is impossible for You to comply with any of the terms of this |
| License with respect to some or all of the Covered Software due to |
| statute, judicial order, or regulation then You must: (a) comply with |
| the terms of this License to the maximum extent possible; and (b) |
| describe the limitations and the code they affect. Such description |
| must be placed in a text file included with all distributions of the |
| Covered Software under this License. Except to the extent prohibited |
| by statute or regulation, such description must be sufficiently |
| detailed for a recipient of ordinary skill to be able to understand it. |
| |
| 5. Termination |
| |
| 5.1. The rights granted under this License will terminate automatically |
| if You fail to comply with any of its terms. However, if You become |
| compliant, then the rights granted under this License from a |
| particular Contributor are reinstated (a) provisionally, unless and |
| until such Contributor explicitly and finally terminates Your grants, |
| and (b) on an ongoing basis, if such Contributor fails to notify You |
| of the non-compliance by some reasonable means prior to 60 days after |
| You have come back into compliance. Moreover, Your grants from a |
| particular Contributor are reinstated on an ongoing basis if such |
| Contributor notifies You of the non-compliance by some reasonable |
| means, this is the first time You have received notice of |
| non-compliance with this License from such Contributor, and You become |
| compliant prior to 30 days after Your receipt of the notice. |
| |
| 5.2. If You initiate litigation against any entity by asserting a |
| patent infringement claim (excluding declaratory judgment actions, |
| counter-claims, and cross-claims) alleging that a Contributor Version |
| directly or indirectly infringes any patent, then the rights granted to |
| You by any and all Contributors for the Covered Software under Section |
| 2.1 of this License shall terminate. |
| |
| 5.3. In the event of termination under Sections 5.1 or 5.2 above, all |
| end user license agreements (excluding distributors and resellers) |
| which have been validly granted by You or Your distributors under this |
| License prior to termination shall survive termination. |
| |
| 6. Disclaimer of Warranty |
| |
| Covered Software is provided under this License on an “as is” |
| basis, without warranty of any kind, either expressed, implied, or |
| statutory, including, without limitation, warranties that the Covered |
| Software is free of defects, merchantable, fit for a particular purpose |
| or non-infringing. The entire risk as to the quality and performance of |
| the Covered Software is with You. Should any Covered Software prove |
| defective in any respect, You (not any Contributor) assume the cost of |
| any necessary servicing, repair, or correction. This disclaimer of |
| warranty constitutes an essential part of this License. No use of any |
| Covered Software is authorized under this License except under this |
| disclaimer. |
| |
| 7. Limitation of Liability |
| |
| Under no circumstances and under no legal theory, whether tort |
| (including negligence), contract, or otherwise, shall any Contributor, |
| or anyone who distributes Covered Software as permitted above, be |
| liable to You for any direct, indirect, special, incidental, or |
| consequential damages of any character including, without limitation, |
| damages for lost profits, loss of goodwill, work stoppage, computer |
| failure or malfunction, or any and all other commercial damages or |
| losses, even if such party shall have been informed of the possibility |
| of such damages. This limitation of liability shall not apply to |
| liability for death or personal injury resulting from such party’s |
| negligence to the extent applicable law prohibits such limitation. Some |
| jurisdictions do not allow the exclusion or limitation of incidental or |
| consequential damages, so this exclusion and limitation may not apply |
| to You. |
| |
| 8. Litigation |
| |
| Any litigation relating to this License may be brought only in the |
| courts of a jurisdiction where the defendant maintains its principal |
| place of business and such litigation shall be governed by laws of that |
| jurisdiction, without reference to its conflict-of-law provisions. |
| Nothing in this Section shall prevent a party’s ability to bring |
| cross-claims or counter-claims. |
| |
| 9. Miscellaneous |
| |
| This License represents the complete agreement concerning the subject |
| matter hereof. If any provision of this License is held to be |
| unenforceable, such provision shall be reformed only to the extent |
| necessary to make it enforceable. Any law or regulation which provides |
| that the language of a contract shall be construed against the drafter |
| shall not be used to construe this License against a Contributor. |
| |
| 10. Versions of the License |
| |
| 10.1. New Versions |
| |
| Mozilla Foundation is the license steward. Except as provided in |
| Section 10.3, no one other than the license steward has the right to |
| modify or publish new versions of this License. Each version will be |
| given a distinguishing version number. |
| |
| 10.2. Effect of New Versions |
| |
| You may distribute the Covered Software under the terms of the version |
| of the License under which You originally received the Covered |
| Software, or under the terms of any subsequent version published by the |
| license steward. |
| |
| 10.3. Modified Versions |
| |
| If you create software not governed by this License, and you want to |
| create a new license for such software, you may create and use a |
| modified version of this License if you rename the license and remove |
| any references to the name of the license steward (except to note that |
| such modified license differs from this License). |
| |
| 10.4. Distributing Source Code Form that is Incompatible With Secondary |
| Licenses |
| |
| If You choose to distribute Source Code Form that is Incompatible With |
| Secondary Licenses under the terms of this version of the License, the |
| notice described in Exhibit B of this License must be attached. |
| |

| |
| If it is not possible or desirable to put the notice in a particular |
| file, then You may include the notice in a location (such as a LICENSE |
| file in a relevant directory) where a recipient would be likely to look |
| for such a notice. |
| |
| You may add additional accurate notices of copyright ownership. |
