[gentoo-user] [FAQ] How to recover from an unsuccessful build

[Helmut Jarausch]

Hi,

when I emerge many packages (currently more than 3000), emerge nearly  
never succeeds.
Yes, I'm using the option --keep-going but this doesn't help most of  
the time.

I have the complete emerge command in one file which has lots of lines.
Now I have the problem to remove those packages from this file which  
have been successfully emerged.

Currently I have written a Python program to scan /var/log/emerge.log  
to extract packages which have been
emerged and which then removes these from my original file.
This still needs some manual tweaking in the case when a packages has  
to be installed more than once (into different slots).

Is there a more elegant solution to this probably most common problem?

Many thanks for  some hints,
Helmut
