 |
|
Hello, ok i getting ready to do install this evening and want to emerge all applications i need overnight. I want to be able to do this without whole process dying if one ebuild fails?
I know emwrap script can do this for upgrades but this no suitable for new install, i text file of all apps i need to install.
any ideas?
cheers

simply use a script with emerge --resume --skipfirst or a script with single emerge but If you are thinking to emerge world or system is not so good to do (I think you know the reason) but if you are know what are doing is suitable.
If you are only thinking to emerge the various applications after the base system is competed, by example if you will not use of the kde/gnome full packages but only by splitted ebuiild try this or something similar:
| Code: | #!/bin/bash
appications="cat/package1 cat/package2 ..."
failed=""
for p in $applications
#or to use command line
#for p in $@
#or to use a file
#for p in $((cat mylsit))
do
emerge $p || failed="$failed $p"
#or if you will to try to build some of the dependancies to save time as try to rebuild the failed compile:
# emerge $p && { failed="$failed\n $p"
# e=0
# until [ $e != 0 ]
# do
# emerge --resume --skipfirst ; e=$?
# done
done
echo "Fail to build: $failed"
#or
#echo $failed > failed_list |
bash scripting is your friend  and there is a good guide to begin in the gentoo documentation. 
Note: emerge --resume --skipfirst will return 0 if there are no more builds to resume and an error code >0 if some of them fail. This is the secret.

Thanks for reply, i no good at bash scripting 
I want to install main system then install all the apps i normally use including kde-meta xorg etc.
I have a text file with list apps though may need refining this to remove some apps that would compile twice as they are dependencies, would it be possible to modify your script to pull in apps to be emerge from this text file?
cheers

Hello, your script worked, well sort of, the only problem was that if an app was dependency of more than one app it would end emerging it again and again, it did not seem to recognise that it was already installed?
cheers

 Having a dependance in the world file can be a problem (in update you will emerge the latest stable version of the package and can be greater than the latest version required) but simply you can use the -n option of emerge if is your intention or test if is installed and skip it.
In the second case the script will be | Code: |
#!/bin/bash
applicatons="cat/package1 cat/package2 ..."
for p in $application
#or to use command line
#for p in $@
#or to use a file
#for p in $((cat /somewhere/mylist))
installed=$((eix -I --only-names $p | grep -v "No matches found" | wc -l))
if [ $installed -gt 0 ]; then
emerge $p || echo $p >> /somewhere/failed-lst
#or if you will to try to build some of the dependancies to save time as try to rebuild the failed compile:
# emerge $p && { echo $p >> /somewhere/faled-list
# e=0
# until [ $e != 0 ]
# do
# emerge --resume --skipfirst ; e=$?
# done
else
echo $p >> /somewhere/skiped-list
fi
done
echo "Fail to build:"
cat /somewhere/failed-list
echo "skipped as already installed:"
cat /somewhere/skipped-list

Thanks for reply, i had this issue with new install so there was no updates, just that when looking at portage logs i could see some apps had been compiled 2/times even though they had only been listed once in script.
