emerge: separate compile and install

[sschlueter]

Is there a way to tell emerge to compile a package but not immediately install it? I already know "emerge -B" but that can't handle dependencies.

The reason why I want to do this is that I have experienced strange things happening when updating a package while the application/daemon/whatever was running.

Let's say I want to upgrade KDE from 3.1.1a to 3.1.2. Of course compiling takes a lot of time and I still want to use KDE during that period of time. If I simply type "emerge kde", the system will become somewhat inconsistent during different periods of time (kdelibs already updated but none of the apps, app running but the binary got already overwritten with the new version, ...)

So I think I want to compile the packages and not installing them, and then shutting down the daemon/logging out of KDE/going single user/etc. and install the packages and restart the daemon/start using KDE again/going multiuser/etc.

The problem is that e.g. "emerge -B kde" doesn't work because of the dependencies. Is there a different possibility?

(I know that I could build the tbz2 files on a different machine but that's not an options for me right know.)

Thanks for your help

Have a look at the ebuild command.

ebuild <foo.ebuild> {unpack,compile,install,etc...}
man ebuild
