Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

We are releasing GNU toolchains of using GNU source code for different targets (RX, RL78). Is it mandatory to provide sources along with the toolchain binaries that we released on our company website?

Or can be provided on request basis?

The GPL version is fairly important here but it's likely that you don't have to include actual source code with the binary, just an offer to make it available. If in doubt, talk to a laywer.

GPL v2 gives you an alternative to including the source, a "written offer":

Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange;

GPL v3 embellishes on this and gives you more options (but also more restrictions), see section 6. Conveying Non-Source Forms of the GPL license.

Yeah; that's true, but be aware that anybody who receives a written copy would be able to distribute it themselves, so you can't really limit distribution by doing this. What are you trying to achieve by not offering the source for download alongside the binaries? I think it's likely to not prove that productive in the long run. –  Iain Lane Nov 21 '13 at 11:44
