Bug 84813 – emerge --update world fails due to emul-linux-x86-xlibs blocking xorg-x11

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description justin moser 2005-03-10 19:26:39 UTC]

the title is pretty straight forward. on the amd64 architecture, when i try to update the system on my amd64 platform, xorg-x11 get's blocked, meaning the whole emerge job fails. 

what is particularly strange about apparently what is happening is xorg is blocking its own dependancy. when i tried to emerge xorg by itself, it gave me the same error. here is the result of pretend install:

 # emerge --pretend xorg-x11

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[blocks B     ] <=app-emulation/emul-linux-x86-xlibs-1.2-r3 (is blocking x11-base/xorg-x11-6.8.2-r1)
[ebuild     U ] x11-base/xorg-x11-6.8.2-r1 [6.8.0-r5]


I also tried removing "emul-linux-x86" from my make.conf temporarily, and the result was the same.


Reproducible: Always
Steps to Reproduce:
1. on amd64, emerge --sync
2. emerge xorg-x11
3. watch in shear horror ;)

Actual Results:  
xorg-x11 and emul-linux-x86-xlibs fail to build.

Expected Results:  
emerge successfully completes without errors. :)

[Comment 1 Herbie Hopkins (RETIRED) 2005-03-11 03:06:23 UTC]

xorg-x11 blocks <=emul-linux-x86-xlibs but xlibs-1.2-r7 is now stable so:
# emerge emul-linux-x86-xlibs
# emerge xorg-x11
i.e get the latest emul-linux-x86-xlibs first and then xorg-x11 will be happy.

However as has been pointed out this is not obvious to the user. Maybe the block should be removed and replaced by some logic to detect the an old -xlibs which causes the ebuild to die and print a message structing the user to upgrade first?
