I have a simular problem. Check if youre worldfile (/mnt/hda5/var/cache/edb/world) is gone (emthy). At least so is mine.

To those helping us: is there a way to restore my worldfile?

[Comment 2 Andy Koch 2004-02-10 11:16:54 UTC]

Yep.  /var/cache/edb/world is a zero byte file.

[Comment 3 Sveinung Kvilhaugsvik 2004-02-10 14:13:11 UTC]

Are you out of diskspase?
After I deleted some files and did "emerge sync" emerge world -up works fine. 
However my worldfile is still gone...  (/var/cache/edb/eclass.pickle seems to contain the name of at lest some installed packages, but I am not sure if it is a complete list, and also dependencyes are listed her) 

[Comment 4 Andy Koch 2004-02-10 21:51:02 UTC]

Sure was out of disk space.  I was trying to emerge gcc when I ran out of disk space and it also failed (due to the disk space).  I guess it triggered this problem too.

Well. As you suggested, I freed up some space, ran emerge sync and now emerge -up world no longer errors, but my world file is still shot.

quick & dirty world file creator - searches for all installed ebulds and prints them out

I did some digging around and found this tool called gencheck,
http://www.kolbu.com/source_code.php and code
http://www.kolbu.com/gentoo/gencheck and made a few modifications so it can
build a new world file.

[Comment 6 Andy Koch 2004-02-10 22:06:19 UTC]

You will need to direct the output of that script into your world file.
#world_creator > /var/cache/edb/world

And with that, I think we are good to go.

corrected a flaw - need to add a newline to the end of each entry.

Thankyou, the script works fine! (of corse, it is Perl :) )

I also got the problem from emerging gcc, so oure problems were quite
identical.

Youre script inspired me to do some coding myself, so I have now created a
script to clean up the worldfile a little bit more efficient. I uploaded it
here in case you are intrested...

[Comment 9 Sveinung Kvilhaugsvik 2004-02-11 13:50:24 UTC]

PS! The script only has 'world' (this dir) as the worldfile. You should change it to the path to the worldfile you wishes to edit...
