<p>Why is this needed? Did you read the commit message of Milian's commit I referenced?</p>
<p>Take a working dir that's somewhere hidden behind a long access path (like what Linux will give to auto-mounted external drives), let's assume that you're using an out-of-source build approach where the source dir and the build dir live under a same parent. (Not crucial for the argument but I just work that way.)</p>
<p>You do the initial cmake run using the actual path, and then at some point you get tired of typing the long path so you create a symlink from a regular work directory under your $HOME to that working dir on the external.</p>
<p>KDevelop's build tree will contain auto-generated files that include headerfiles with paths like ../../../kdevelop-source/kdevplatform/interfaces which are representative for the actual locations on disk. Accessing that build directory via <tt style="background: #ebebeb; font-size: 13px;">(cd link-to-work/build ; make)</tt> will lead to all kinds of failures if make (and thus potentially cmake) finds itself executing under <tt style="background: #ebebeb; font-size: 13px;">/home/joe/work/coding/link-to-work/build</tt> instead of something like <tt style="background: #ebebeb; font-size: 13px;">/media/joe/JoesExternal/coding/KDE/KDevelop/build</tt>. Headerfiles expected under relative paths may not longer be found.</p>
<p>It's taken me a few days to realise why I kept getting those non-canonical shortcut paths in my compile commands after I rewrote my wrapper scripts to use canonical paths</p>
<p>There's another argument why this is a good idea: cross-platform consistency. On Mac it's impossible to avoid path normalisation and there may be other platforms where this is true too.</p></div></div><br /><div><strong>CHANGES SINCE LAST UPDATE</strong><div><a href="https://phabricator.kde.org/D7930?vs=19763&id=19767" rel="noreferrer">https://phabricator.kde.org/D7930?vs=19763&id=19767</a></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D7930" rel="noreferrer">https://phabricator.kde.org/D7930</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>plugins/cmake/cmakecommitchangesjob.cpp<br />
