Bug 774717 – dev-qt/qtwebengine-5.15.2 without X11 dependencies

• Product: Gentoo Linux
• Status: UNCONFIRMED ---

[Description Michel Ganguin 2021-03-07 18:37:19 UTC]

qtwebengine does not require X11 (neither build time nor runtime) when running on non-x11 platforms (eglfs, linuxfb, wayland). However the ebuild requires mesa[X] and multiple x11-libs/* libraries.

I suggest adding the X use flag to make it optional. The flag would be default enabled or maybe even masked if this change is considered as potentially impacting people needing X dependency.

Reproducible: Always

Steps to Reproduce:
1. Have mesa built without X
2. emerge qtwebengine
Actual Results:  
emerge qtwebengine wants a use flag change on mesa and pulls x11-libs/* dependencies

Expected Results:  
build without X dependencies

Add X use flag

Add X use flag:
* use it in the mesa use flag dependency
* place x11-libs/* behind the X use flag (except x11-libs/libdrm which is not really an x11 package)

This patch is incomplete without setting an according qtwebengine build switch. Is there such a build switch? If not, this relies on automagic and cannot be exposed to an IUSE.

add X use flag with disalbing X auto-detection

Second tentative, took me a while to get into QT build system and portage qt5-build eclass. Hope this will go through.

Any updates? it has been about 3 months and I implemented @Andreas Sturmlechner recommendation.
