Description Martin Mokrejš 2021-03-17 14:08:01 UTC
  I am installing and EPREFIXed gentoo instance andseems the dependencies are not defined properly.

I have sys-fs/eudev-3.2.10 already installed.

I do have /foo/gentoo/usr/lib64/ .Well, there is no '-L' on the link line.

Yes, maybe something is wrong with parsing the complicated paths? There is a symlinked NFS-based directory in there so the 'foo' and 'baz' are practivally same but as you can see, gcc-picked up both.

It is true that  complained to me that I want to install gcc into a location which needs to be resolved via the symlink and it is known to be broken. Provided I installed system up to stage3 I doubt I am affected but nevertheless wanted to mention that.

Comment 1 Ionen Wolkens gentoo-dev 2021-03-18 11:18:55 UTC
pciutils[udev] seems fine on my own amd64 prefix, and the linking line is identical.

But when I look at the symlink I do feel like something "could" go wrong.

Target exists but for me it's a whole: -> ../../../../../home/ionen/prefix/lib64/

Is it valid for you?
Comment 2 Martin Mokrejš 2021-03-18 11:38:02 UTC
Thank you. Right, on the very same machine the ls(1) output blinks the symlink on 3rd line in red, as it points to nowhere:

lrwxrwxrwx 1 mmokrejs meta     16 Mar 17 14:44 /storage/brno3-cerit/home/mmokrejs/gentoo/lib64/ ->

lrwxrwxrwx 1 mmokrejs meta     84 Mar 17 14:44 /storage/brno3-cerit/home/mmokrejs/gentoo/usr/lib64/ -> ../../../../../../../storage/brno3-cerit/home/mmokrejs/gentoo/lib64/
-rw-r--r-- 1 mmokrejs meta    655 Mar 17 14:44 /storage/brno3-cerit/home/mmokrejs/gentoo/usr/lib64/pkgconfig/libudev.pc

$ cd /storage/brno3-cerit/home/mmokrejs/gentoo/usr/lib64/
$ ls -latr
lrwxrwxrwx 1 mmokrejs meta 84 Mar 17 14:44 -> ../../../../../../../storage/brno3-cerit/home/mmokrejs/gentoo/lib64/
$ file broken symbolic link to ../../../../../../../storage/brno3-cerit/home/mmokrejs/gentoo/lib64/

The real fs mount point is /mnt/storage-brno3-cerit, then

/storage/brno3-cerit symlinks to /mnt/storage-brno3-cerit/nfs4

I assume it is because the path when resolved with the "nfs4" in its name is longer by one. I guess during libudev install the ... libtool? package create the path when think it is under /mnt/storage-brno3-cerit/nfs4 path while later it get executed through /storage/brno3-cerit path. But why does this happen only for a single package? Maybe the error message from was :correct"?

$ ./ 

The "problem is" that the mounts are done in a different way on the cluster and that is why there is a unified symlinked path as e.g. /storage/brno3-cerit and that was the one I wanted to tell gentoo-prefix to pick. All tools works IMO except this one.
Comment 3 Fabian Groffen gentoo-dev 2021-03-18 11:43:24 UTC
In your case I suggest to just fix the symlink manually, because this really is nasty to take care of.  Hence we don't support this setup.
Comment 4 Martin Mokrejš 2021-03-18 11:48:56 UTC
Maybe readlink or some other utility could be used or improved to shorten the path? Now on the broken symlink it cannot probably do any better but during installation of libudev it could have shortened the relative path to ../../lib64/

$ readlink
Comment 5 Martin Mokrejš 2021-03-18 11:57:40 UTC
rm; ln -s ../../lib64/
rm; ln -s ../../lib64/ # from sys-apps/kmod-28

There were no more issues. I tested like this:

$ ln -s ../dsdsd/sds junksss
$ find ./ -type l -exec file {} \; | grep broken
./junksss: broken symbolic link to ../dsdsd/sds

Maybe some portage class could have taken care of this? Still I wonder why this happened for only two packages.
