• Status: RESOLVED
• Resolution: INVALID
• Component: WebKitGTK

[Alberto Garcia]

WebKitGTK 2.42.5 has recently stopped building in Debian unstable due to the following linking errors:

This is gcc 13.2.0-18 from Debian.

WPE WebKit (same version) does not seem to be affected by this.

Never mind, this was caused because I was accidentally using -Werror=implicit-function-declaration for C++ files.

Closing as invalid.
