Bug 536188 – =dev-qt/qtwebkit-5.4 - The WebKit build was disabled for the following reasons: Missing gperf from PATH

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Paweł Stankowski 2015-01-10 11:02:14 UTC]

qtwebkit emerged "successfully", but no files are installed.

dev-qt/qtwebkit-5.4.0 was built with the following:
USE="opengl udev -debug -gstreamer -gstreamer010 -multimedia -printsupport -qml -test -webp" ABI_X86="64"


Reproducible: Always

Emerging dev-util/gperf-3.0.4 fixed the problem.

The other revealed problem is that emerge did not fail when it should (probably due to missing 'die' command somewhere).

No it's not a missing die. The build system by design doesn't build anything if some basic dependencies are missing, so there's no error and the process exits successfully.

The gperf dep has been added. Thanks.

Sound like a good design when you build whole Qt at once, but it should not work like that when only qtwebkit is built.

I propose following patch:
