<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;"><code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">KDevelop/languages/plugins/custom-definesandincludes/idefinesandincludesmanager.h:54: error: undefined reference to 'vtable for KDevelop::IDefinesAndIncludesManager'

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The GCC bugzilla suggests two workarounds:<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
1. Defining this implicitly inlined, defaulted destructor outside the class<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
2. Adding a <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">noexcept</code> declaration to derived destructors.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The second is obviously the most appealing and least intrusive fix, unfortunately, I couldn't seem to get it to compile owing to the concrete DefinesAndIncludesManager class becoming an incomplete type, possibly because the virtual IDefinesAndIncludesManager destructor was being inline'd out of existence (despite being marked virtual?), so I have implemented the former of the two workarounds and tagged it with a HACK. This fix was prompted by several callers to #kdevelop whom all seemed to be running afoul of this issue. As the 4.7 branch is still in moderate use, it may be worth it to just bite the bullet and apply this for now.</p></pre>
