Linux Download:

(current with Version 8.0.5 — Last updated 2nd June 2020)

64-bit Linux Executables

Built on Centos 7 using GCC 4.8.5

Note: these do not include the “kdu_show” application, which involves some platform dependent code.

Other Platforms:

The Kakadu software tools are platform independent.

Only some aspects of the interactive “kdu_show” application contain platform-specific elements, but that’s all. Even in this application, all of the interesting tasks are performed by platform-independent code.

Developers should find the tools equally useful regardless of their preferred development or target platform.

Licensed copies of the source come with Makefiles which have been tested on a variety of platforms with gcc.

Licensed copies also come with a full set of Java native bindings, allowing platform dependent aspects of a viewer or networked application to be abstracted in Java, without sacrificing the power and speed of Kakadu. Licensed copies also come with a full set of bindings for C# and VB developers.
