The existing test fails on several systems due to GL runtime version mismatches, the use of deprecated features, and memory errors due to improper use of GLUT. The test was modified to: - Run within a display function, allowing proper GLUT cleanup. - Generate dynamic shaders with a supported GLSL version string and output variables. - Report shader compilation errors. - Check GL context version before launching version-specific tests. Note that most of the existing `OpenGLSupport` module and tests rely on deprecated features (e.g. fixed-function pipeline). The test was modified to allow it to pass on various systems. We might want to consider removing the module or re-writing it entirely to support modern OpenGL. This is beyond the scope of this patch. Testing of legacy GL (for platforms that support it) can be enabled by defining `EIGEN_LEGACY_OPENGL`. Otherwise, the test will try to create a modern context. Tested on - MacBook Air (2019), macOS Catalina 10.15.7 (OpenGL 2.1, 4.1) - Debian 10.6, NVidia Quadro K1200 (OpenGL 3.1, 3.3) |

This directory contains contributions from various users. They are provided "as is", without any support. Nevertheless, most of them are subject to be included in Eigen in the future. In order to use an unsupported module you have to do either: - add the path_to_eigen/unsupported directory to your include path and do: #include <Eigen/ModuleHeader> - or directly do: #include <unsupported/Eigen/ModuleHeader> If you are interested in contributing to one of them, or have other stuff you would like to share, feel free to contact us: http://eigen.tuxfamily.org/index.php?title=Main_Page#Mailing_list Any kind of contributions are much appreciated, even very preliminary ones. However, it: - must rely on Eigen, - must be highly related to math, - should have some general purpose in the sense that it could potentially become an official Eigen module (or be merged into another one). In doubt feel free to contact us. For instance, if your addons is very too specific but it shows an interesting way of using Eigen, then it could be a nice demo. This directory is organized as follow: unsupported/Eigen/ModuleHeader1 unsupported/Eigen/ModuleHeader2 unsupported/Eigen/... unsupported/Eigen/src/Module1/SourceFile1.h unsupported/Eigen/src/Module1/SourceFile2.h unsupported/Eigen/src/Module1/... unsupported/Eigen/src/Module2/SourceFile1.h unsupported/Eigen/src/Module2/SourceFile2.h unsupported/Eigen/src/Module2/... unsupported/Eigen/src/... unsupported/doc/snippets/.cpp <- code snippets for the doc unsupported/doc/examples/.cpp <- examples for the doc unsupported/doc/TutorialModule1.dox unsupported/doc/TutorialModule2.dox unsupported/doc/... unsupported/test/.cpp <- unit test files The documentation is generated at the same time than the main Eigen documentation. The .html files are generated in: build_dir/doc/html/unsupported/
