Bug 528230 – x11-base/xorg-server-1.16.1 USE=kdrive automagically depends on x11-libs/xcb-util-*

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Ruslan Savchenko 2014-11-04 14:22:01 UTC]

Different sources on the internet say that you need to add kdrive USE flag to x11-base/xorg-server package in order to build Xephyr. It turned out that xcb-utils* packages are required.

When I've tried to run x11-base/xorg-xserver configure with --enable-xephyr, it failed:

configure: error: Package requirements (xau xdmcp xcb xcb-shape xcb-aux xcb-image xcb-icccm xcb-shm xcb-keysyms xcb-xv libdrm xcb-glx xcb-xf86dri > 1.6) were not met:

No package 'xcb-image' found
No package 'xcb-icccm' found
No package 'xcb-keysyms' found


So I realized that xephyr depends on xcb-utils*. Ater I did 


1. emerge xcb-utils

localhost x11-base # emerge -vD xcb-util 

These are the packages that would be merged, in order:

[ebuild  N     ] x11-libs/xcb-util-wm-0.4.1-r1  USE="-doc -static-libs {-test}" ABI_X86="(64) -32 (-x32)" 0 KiB

2. added xnest USE flag for x11-base/xorg-xserver
3. emerge -1 xorg-server

Xephyr is present.



Reproducible: Always

Steps to Reproduce:
1. emerge -C xcb-util-renderutil xcb-util-wm xcb-util-keysyms xcb-util-image
2. emerge -1 xorg-server
3. ls /usr/bin/Xephyr
Actual Results:  
ls: cannot access /usr/bin/Xephyr: No such file or directory

Expected Results:  
-rwxr-xr-x 1 root root 2355536 Nov  4 17:02 /usr/bin/Xephyr

Sorry about that. Should be read as kdrive USE flag.

[Comment 4 Pacho Ramos 2015-01-18 11:07:16 UTC]

Should a xephyr USE be added to control this or we don't want it to be optional with kdrive is enabled?

[Comment 5 Chí-Thanh Christopher Nguyễn 2015-01-21 18:05:53 UTC]

Adding the xcb-util-* dependencies is probably the way to go. If someone has a use case to build kdrive without xephyr, a separate enhancement bug would be the best idea.

[Comment 6 Pacho Ramos 2015-01-22 10:15:55 UTC]

should then we also pass $(use_enable kdrive xephyr) to ensure xephyr is always built?

[Comment 7 Matt Turner 2015-01-22 23:36:07 UTC]

I've pushed a patch that adds a xephyr USE flag to xorg-server-9999 in the overlay. I don't think the dependencies are quite right though.

[Comment 8 Pacho Ramos 2015-01-23 09:45:42 UTC]

What should we do for 1.16.x? (please not this is blocking the xorg stabilization bug for December ;))

Sorry, I don't understand. Do you want me to fix this for 1.16.x as well?

[Comment 10 Pacho Ramos 2015-01-24 09:39:53 UTC]

Well, at some point this was considered as a blocker for bug 530652 then, we would need to fix it if possible. On the other hand if you think it's not safe enough and not a real blocker we can also drop the block :/ (but I am not a X11 team member ;)

[Comment 11 Pacho Ramos 2015-01-27 10:28:37 UTC]

(drop the blocker as talked with chithead on IRC :)

[Comment 12 Matt Turner 2015-02-22 02:49:43 UTC]

I've added proper dependencies for IUSE=xephyr to 1.17.1 and 9999.
