As reported in this post by Robert Bisewski: https://lists.webkit.org/pipermail/webkit-gtk/2017-April/003012.html Original e-mail text follows. ---- I was attempting to compile my webkit2-based browser `sighte` using the new v2.16.1 release of webkit2-gtk when I noticed the following warning from my gcc v6.3.0 compiler: /usr/include/webkitgtk-4.0/webkit2/WebKitAutocleanups.h:83:77: warning: ISO C does not allow extra ‘;’ outside of a function [-Wpedantic] G_DEFINE_AUTOPTR_CLEANUP_FUNC (WebKitWebsiteData, webkit_website_data_unref); This is no means a hold up for my project, but the warning did not appear before, so I figured taking a bit of time to track down exactly what was causing it would be in order. While I am not exactly well-versed at your code base, just glancing quickly from Trac leads me to believe that the specific commit appears to be this one: https://trac.webkit.org/changeset/214163/webkit Simply removing the aforementioned ; character from the file WebKitAutocleanups.h on line 83 seems to resolve the warning in question. If adding the semi-colon is not intended, then I hope you find this helpful :)
