Sure.<br>

Of course, like any normal binary that is linked against a library in<br>
Debian.<br>

As my other bug, node-expat seems to have the same issue.<br>

That doesn't scale, because it's every package that has an autopkgtest<br>
that depends on node-iconv that has this issue. So it's node-iconv that<br>
needs to declare the right versioned relation to nodejs. It looks like<br>
the binary executable already knows it, but the Debian package doesn't<br>
know it yet. The internal knowledge needs to be exposed somehow.<br></blockquote><div><br></div><div>Since all packages that Build-Depend: libnode-dev are concerned,</div><div>maybe the solution is to declare:</div><div><br></div><div>libnode-dev</div><div>Depends: nodejs (= ${binary:Version})</div><div><br></div><div>- downside: packages depending on libv8-dev will install nodejs (this shouldn't be a problem).</div><div>- a multi-arch issue ?</div><div><br></div><div>?</div><div><br></div></div></div>
