Report a Bug

Before sending a bug-report, you should check the FAQ and our issue tracker on GitHub, where your issue might have already been answered or reported.

If you are using an old version of CGAL, your problem may have already been solved in a more recent release. Please try your program with the latest release.

Bug reports should be made on our GitHub issue tracker (Note that this requires you to have a GitHub account). In your issue, please do include as much information as possible:

• a short, self-contained, correct (compilable), example (see sscce.org), which you should put on gist.github.com;
• which operating system, compiler, and hardware you are using;
• information about how CGAL was installed on your system (i.e., which options were used, how the library was built, etc.);
• any third-party software (such as GMP) that is involved;
• a description of the problem or bug and a way to reproduce it (such as a small sample program or a sequence of commands);
• do not forget to mention which kernel you are using, and check for potential robustness issues you may have;
• in case of run-time crash, please include a stack trace provided by the debugger;
• in case of problems with the installation, make sure to include the install.log file.

The more information you provide, the easier it will be for us to help you quickly solve the problem.
