Bug 71885 – emerging multiple packages at the same time, depend/provide/block checking fails

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

Hi,

I explain this in two examples:

Example #1:
Let's take qc-usb package and it's virtual/linux-sources dependency which isn't satisfied in this case.

Then, if we emerge qc-usb and a pkg which would satisfy this dependency, emerge doesn't count that pkg when checking dependencies of the qc-usb. Instead, it would emerge default choice of the virtual/linux-sources.


# emerge -pt qc-usb gentoo-dev-sources

These are the packages that I would merge, in reverse order:

Calculating dependencies ...done!
[ebuild  N    ] sys-kernel/gentoo-dev-sources-2.6.9-r4
[ebuild  N    ]  dev-libs/ucl-1.01-r1
[ebuild  N    ] media-video/qc-usb-0.6.0
[ebuild  N    ]  sys-kernel/gentoo-sources-2.4.26-r12


Same goes other way round: 


# emerge -pt gentoo-dev-sources qc-usb

These are the packages that I would merge, in reverse order:

Calculating dependencies ...done!
[ebuild  N    ] media-video/qc-usb-0.6.0
[ebuild  N    ]  sys-kernel/gentoo-sources-2.4.26-r12
[ebuild  N    ] sys-kernel/gentoo-dev-sources-2.6.9-r4
[ebuild  N    ]  dev-libs/ucl-1.01-r1

Example #2:
Same problem raises when trying to emerge two packages which block each other at the same time. 

For example: 
emerge -p postfix ssmtp (no blocking errors at all) 
emerge -p ssmtp postfix (blocking error, but still seems to emerge both..)

---

So, emerge should check specified packages for what they provide, and also sort them rightly if some package depends on them. And of course check if some package blocks some other package specified, and in positive case give an error.

If this worked rightly, you would easily emerge those packages you emerged in the previous install just by copying the old world file to the new system and running emerge (-p) $(tr '\012' ' ' < old_world_file) for example. (This is what I originally tried to do.. :)

Thanks,
--jussi
