This distribution contains the code necessary to write MaxMind DB database files. See MaxMind::DB::Writer::Tree for API docs.

If you're running into install errors under Mac OS X, you may need to force a build of the 64 bit binary. For example, if you're installing via cpanm:

ARCHFLAGS="-arch x86_64" cpanm MaxMind::DB::Writer

This distribution does not currently work on Windows. Reasonable patches for Windows support are very welcome. You will probably need to start by making Math::Int128 work on Windows, since we use that module's C API for dealing with 128-bit integers to represent IPv6 addresses numerically.

Please report all issues with this code using the GitHub issue tracker at https://github.com/maxmind/MaxMind-DB-Writer-perl/issues.

We welcome patches as pull requests against our GitHub repository at https://github.com/maxmind/MaxMind-DB-Writer-perl.
