* Licence question regarding the delivery of Cygqin binaries @ 2019-03-29 12:11 Busch, Ciske 2019-03-29 13:41 ` Corinna Vinschen 0 siblings, 1 reply; 4+ messages in thread From: Busch, Ciske @ 2019-03-29 12:11 UTC (permalink / raw) To: cygwin Hi, (I used this email as suggested (in a rather old) forum post from Corinna Vinschen. If this is not the right address I would be very thankful if you could point me to another address.) we have ported an older application from Linux to Windows and plan on using this in a commercial release. Due to the nature of the older application the Windows port uses tools from the Cygwin project which are called either from code or using shell scripts - we do not link either the Cygwin.dll nor any of the tools. You will find examples for scripts and the list of binaries used below. We do not plan on making our application available as open source. Our understanding regarding licensing is that as long as we do not link any part of the Cygwin distribution we are free to use them without implications for our own software. However we are not allowed to include the Cygwin binaries within the installer of our application - which is a problem for us as we need to have control over the versions our end users have installed. So my question is: is there a way for us to acquire a license which would allow us to "bundle" the required Cygwin components with our software? Thank you for your help!

The Cygwin DLL itself is LGPLv3+. The tools part of the Cygwin build itself are GPLv3+. All other Open Source tools not covered by the Cygwin license retain their respective license. Most of the licenses require you, the vendor, to provide the source code of these tools under the conditions of their respective license to your customers. Some licenses also require to add license information to your documentation. There is no bundle licensing available! Ideally you should add the sources of all Open Source software part of your commercial offering to your software package, as well as adding the OSS licensing information for all packages to your documentation. However, you should really check your licensing situation with a lawyer skilled in sofware licensing issues. Naturally we can't give you any viable advice in terms of licensing compliant behaviour here.

You may find similar approaches used in apps and embedded devices built using open source components if you look in the documentation for those you have. You may be able to find more advice at https://www.fsf.org/licensing. Once you have an approach, and maybe also a repository, with component build instructions, contact them directly for a compliance check and advice. Do this before you distribute anything, as getting into compliance after breaching a licence requires more effort than being compliant. You may find more useful information in: https://copyleft.org/guide/comprehensive-gpl-guidepa2.html and the associated website as well as https://sfconservancy.org/. These orgs are more interested in ensuring vendors are compliant by following community guidelines than enforcing compliance with legal threats and lawsuits, although they are prepared to do so and successful in doing so. P.S. Cygwin builds and instructions can be abbreviated using Cygwin setup to install all Base packages, plus cygport and its dependencies and your required package sources, and using cygport to build your required packages. For Cygwin licensed components which are packages, the following command should show all applicable licences for all installed packages: $ ls /usr/share/doc/**/*{COPYING,LI[CS]EN[CS]E}* although for a selection of packages you may want to be more specific and thorough using the find utility on selected package doc or src directories. -- Take care.
