License file

[nowls]

Could you please add a LICENSE file in the repository root directory as you did with libairspyhf?

[bvernoux]

It is not as simple as there is multiple licenses depending on directories:

• Files under https://github.com/airspy/airspyone_host/tree/master/airspy-tools are GPL-2.0
• Files under https://github.com/airspy/airspyone_host/tree/master/libairspy are BSD-3-Clause

So we could probably add that in each directory to clarify the license for each part and maybe add this comment at end of https://github.com/airspy/airspyone_host/blob/master/README.md

Any proposal are welcome

I think the license-file-per-component model works well. The reason I'm requesting this feature is so I can point to a license file to build the libairspy component in OpenEmbedded. The build system tracks license files for you so embedded Linux developers can easily verify license compliance throughout the build.

I have added license for

• airspy-tools
• airspy-tools/getopt
• libairspy/vc/getopt

But after check libairspy/src is even more complex as it have a mix of MIT License & BSD 3-Clause License

[nowls]

Hmm, yes that is more complex. What I'm looking for is a stable LICENSE or COPYING file whose contents won't change unless you decide to change the licensing under which your code is released. I believe this could be done like follows:

For file XXX:

<BSD 3-Clause license text>

For file YYY:

<MIT license text>

The Apache project does something like that: https://github.com/apache/httpd/blob/trunk/LICENSE

[bvernoux]

In clear:

• airspy-tools examples are GPL in order to have contributions
• LIB / DLL source code is MIT / BSD 3-Clause in order to integrate it in some software without redistributing or contributing ... (could be used in closed product)

[nowls]

Understood. For Lib/DLL source, I'm thinking of something along the lines of this file, which I believe accurately covers all the .c and .h files in libairspy/src:

[nowls]

This was addressed satisfactorily.
