ITK License Compatibility Concern with VNL

Community

Hello,

I have noticed a potential licensing conflict in ITK related to third-party code from VNL. While ITK is distributed under the permissive Apache 2.0 license, which allows commercial use, I found that the VNL module includes a file that may not be compatible with these terms.

Specifically, the file rpoly.f used by Netlib, is part of the Collected Algorithms (CALGO) from ACM and is distributed under the ACM Software License Agreement. This file was added 19 years ago to the VNL GitHub repository, which appears to place it under the following licensing condition:

Given this, it seems that ITK may not be suitable for direct commercial use. Does this interpretation seem correct? Otherwise, is there a way to compile ITK without VNL, thereby avoiding the inclusion of this file?

Thank you for your insights.

ITK has been used for commercial purposes since its inception. I assume that approval was obtained. @hjmjohnson might know more.
