[gentoo-user] stop an emerge (compilation), halt the PC, boot and continue the emerge

[Hogren]

 

 

Hello !!

I have a little question about portage.

There are many big softwares like Firefox, LibreOffice. At a certain moment, I need to stop the compilation to halt the PC.

But, when I boot up again the PC and I «emerge --resume», it restart the compilation process.

Is there a way to not restart the compilation process ?
I think that if I enter in the temp directory and I type «make && make install», it will install the software but it will not update portage database.


Thank you for your response !

Bye

Usually what I'll do is ctrl-z which pauses emerge, and then I'll run pm-suspend to put the machine to sleep. After I turn it back on again I'll issue fg and emerge will resume.

The --resume flag just attempts to continue a failed emerge list.

Hogren,
What I do may be of help, but then again, it may be all wrong and one
day the gates of hell may open up and swallow mankind because of what I
did, but hey, that's life.

There is the FEATURES entry in make.conf, man make.conf. Within this
are two options "keeptemp" and "keepwork". I enable them, then the
consequences of which is that stuff is not cleaned up. Hence when I
rerun the emerge, the "make" within sees the already existing files and
skips them, in other words it does as "make" is expected to do.

Please bear in mind if you have /var/tmp/portage set up to be a RAM
disk of some sort, obviously if you turn your machine off, you'll look
the intermediate files, but if you are hard disk based, they will be
there when you restart the machine and so when you rerun emerge, the
part up until when you killed the emerge originally will be skipped.

Hope this helps,
Andrew

Take a look at Tux on Ice, this should do the trick for you.

In addition, if you can use the same procedure for hibernate (to disk) if for
some reason you need to completely remove power from your PC.

I had success in the past using ebuild instead of emerge. Check the man
page, briefly emerge is equivalent to the following steps in sequence:

$ ebuild fetch
$ ebuild unpack
$ ebuild compile
$ ebuild install
$ ebuild qmerge

Running 'make' in the temp dir followed by the last two ebuild steps
only (install and qmerge) should work.

This is pretty much what is run when you emerge something.

ebuild [.ebuild] fetch
ebuild [.ebuild] unpack
ebuild [.ebuild] compile
ebuild [.ebuild] install
ebuild [.ebuild] qmerge
ebuild [.ebuild] clean

to continue just choose what part the build was on when you quit it and
start there.

All I really just use is compile and merge. If it didn't get to compile
it isn't worth it. Just emerge the whole thing again.

Yes you can, it is not officially supported to do this but I have done
it several times (webkits, libreoffice) without problems, what I do is
make a binary package and then install it, you should have set $PKGDIR
in make.conf, here's how I've done it:

You stopped at libreoffice, you restart your computer, then you should
find out what is the exact ebuild you were building, equery can help
you, if it is an upgrade, i.e.:

$ equery which libreoffice
${PORDIR}/app-office/libreoffice/libreoffice-5.1.3.2.ebuild

then you pretend you are emerge, by using the portage user to make the
build resume, make sure $PKGDIR is writable by the portage user:

$ sudo -u portage ebuild\
 ${PORTDIR}/app-office/libreoffice/libreoffice-5.1.3.2.ebuild \
package

or nesting both commands:

$ sudo -u portage ebuild $(equery w libreoffice) package

this makes all the previous steps needed (prepare, configure ,build,
install) if they haven't been done,
when that is finished you can merge your recently created binary
package by:

$ sudo emerge -av1K =app-office/libreoffice-5.1.3.2 

and resume the general upgrade with:

emerge --resume -av --exclude app-office/libreoffice

Yes, I know that but I was in a special case where I couldn't use it.

I already have suspend and hibernate command. Is it different ?
