<pre><code class="language-bash">--link [--libraries <LIBRARIES>] <INPUT_FILES>
|

</code></pre>
|
||
<p>In Solidity, 3 things can happen with libraries:</p>
|
||
<ol>
|
||
<li>They are not <code>extern</code>ally callable and thus can be inlined.
|
||
<ol>
|
||
<li>The solc Solidity optimizer inlines those (usually the case). Note: <code>resolc</code> always activates the solc Solidity optimizer.</li>
|
||
<li>If the solc Solidity optimizer is disabled or for some reason fails to inline them (both rare), they are not inlined and require linking.</li>
|
||
</ol>
|
||
</li>
|
||
<li>They are <code>extern</code>ally callable but still linked at compile time. This is the case if at compile time the library address is known (i.e. <code>--libraries</code> supplied in CLI or the corresponding setting in STD JSON input).</li>
|
||
<li>They are linked at deploy time. This happens when the compiler does not know the library address (i.e. <code>--libraries</code> flag is missing or the provided libraries are incomplete, same for STD JSON input). This case is rare because it’s discourage and should never be used by production dApps.</li>
|
||
</ol>
|
||
<p>In cases <code>1.2</code> and <code>3</code>:</p>
|
||
<ul>
|
||
<li>Some of the produced code blobs will be in the “unlinked” raw <code>ELF</code> object format and not yet deployable.</li>
|
||
<li>To make them deployable, they need to be “linked” (done using the <code>resolc --link</code> linker mode explained below).</li>
|
||
<li>The compiler emitted <code>DELEGATECALL</code> instructions to call non-inlined (unlinked) libraries. The contract deployer must make sure to deploy any libraries prior to contract deployment.</li>
|
||
</ul>

|
||
<p>Using deploy time linking is officially <strong>discouraged</strong>. Mainly due to bytecode hashes changing after the fact. We decided to support it in <code>resolc</code> regardless, due to popular request.</p>
|
||
</blockquote>
|
||
<p>Similar to how it works in <code>solc</code>, <code>--libraries</code> may be used to provide libraries during linking mode.</p>
|
||
<p>Unlike with <code>solc</code>, where linking implies a simple string substitution mechanism, <code>resolc</code> needs to resolve actual missing <code>ELF</code> symbols. This is due to how factory dependencies work in PVM. As a consequence, it isn’t sufficient to just provide the unlinked blobs to the linker. Instead, they must be provided in the exact same directory structure the Solidity source code was found during compile time.</p>
|
||
<p>Example:</p>
|
||
<ul>
|
||
<li>The contract <code>src/foo/bar.sol:Bar</code> is involved in deploy time linking. It may be a factory dependency.</li>
|
||
<li>The contract blob needs to be provided inside a relative <code>src/foo/</code> directory to <code>--link</code>. Otherwise symbol resolution may fail.</li>
|
||
</ul>
