GPL: distribute compiled binary
<p>Is it legal to modify GPL v3.0 content and distribute a binary of the remixed content without disclosing the modified source code?</p>

<p>The easiest way for you is to distribute source code and compiled code <em>together</em>. That way you have fulfilled all your GPL obligations and you have no requirement to do anything for anyone in the future.</p>
<p>The alternative is to distribute the compiled code, together with an offer valid for three years to supply the source code on request to <em>anyone</em> ever asking for it. So distributing without supplying the source code <em>right now</em> is legal, but you <em>must</em> supply it later when requested.</p>
