Tested with GNU make (written to be cross-platform) and `g++` on linux/MinGW64, `clang++` on Mac OSX High Sierra, and MSVC on Windows. Our build system depends on the cross-platform `cmake` tooling for Makefile generation.\n\n1. `git clone https://github.com/dsteinmo/blitzdg.git`\n2. `cd blitzdg \u0026\u0026 ./pull-deps.sh`\n3. `cmake . \u0026\u0026 make advec1d \u0026\u0026 ./bin/advec1d` (This binary is a 1D advection equation solver.).\n4. Run unit tests with `make test`.\n\n## Dependencies\n\n* `cmake`\n* `blitz++`\n* `SuiteSparse (umfpack, cxsparse)`\n* `LAPACK`\n* `metis`\n* `igloo` for BDD-style testing.\n* `vtk` for visualization in Paraview.\n* `boost-python3` for python bindings.\n* `boost-numpy3` for numpy C++ interoperability.\n\nDependency installation is outlined in `pull-deps.sh` (tested on Ubuntu and Mac OSX).\n\n### Windows\n\nOur windows distribution was recently switched from MinGW to MSVC in order to achieve better support for graphics APIs, so support is lacking at the moment. Instructions will be made available here soon.\n\n## Contributing\n\nWe accept pull requests from public forks, and we use pull requests as the primary delivery mechanism of any new code within the base repository.\n\nIf you add code, please write tests using the igloo testing framework that is included as a project dependency. Your code additions will be subject to peer review and will be run through our Travis-CI continuous integration process.\n\nInterested developers should consult the [Guidelines for Contributing](https://github.com/WQCG/blitzdg/blob/master/CONTRIBUTING.md \"Contributing Markdown\") before getting started.\n\n## Maintainer\n\n* [Derek Steinmoeller](https://github.com/dsteinmo)\n\n## Lead Developers\n\n* [Derek Steinmoeller](https://github.com/dsteinmo)\n* [Killian Miller](https://github.com/k7miller)\n\n## Documentation\n\nWe actively maintain an interactive set of docs using Doxygen for end-user consumption.\n\nThe documentation is available on github pages at [https://wqcg.github.io/blitzdg](https://wqcg.github.io/blitzdg \"blitzdg Documentation\") and is kept synchronized with the master branch via automation.\n\n## License\n\nThis project is licensed under the [GNU Public License Version 3](https://www.gnu.org/licenses/gpl-3.0.en.html \"GPLv3 License\").\n\nOur license choice is driven by the desire to keep this project and any of its derivative works open-source for public consumption by developers, mathematicians, scientists, engineers, and anyone else who might be interested in this project.\n\n## Contact\n\nAny questions regarding the project may be addressed via email to the [project maintainer](mailto:dsteinmo@wqcg.ca).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fwqcg%2Fblitzdg","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fwqcg%2Fblitzdg","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fwqcg%2Fblitzdg/lists"}
