IKOS[1] (Inference Kernel for Open Static Analyzers) is a static analyzer for C/C++ based on the theory of Abstract Interpretation. IKOS has been released under the NASA Open Source Agreement version 1.3, see LICENSE.pdf [1]: https://github.com/NASA-SW-VnV/ikos
Unfortunately they invented another license and did not even provide it as text file. I do not think that we want to add licenses as PDF to the tree. It would help, if upstream adds a COPYING file in the plain text format to the tree. Because nobody we can not confirm quickly, that the txt is 100% the same as the pdf someone transcribed. https://tldrlegal.com/license/nasa-open-source-agreement-1.3-(nasa-1.3)#summary There are already users compiling it on Gentoo: https://github.com/NASA-SW-VnV/ikos/issues/61 I suggest to put it on an overlay first. see also https://repology.org/project/ikos/versions
@Jonas, I sent them an email from my company address requesting a license change to Apache, maybe that will help :)
Alright, got them to add a COPYING file :)
