Hi, guys!
After recent update emerge --depclean fails to clean the system:
Code:
 # emerge --depclean

 * Always study the list of packages to be cleaned for any obvious
 * mistakes. Packages that are part of the world set will always
 * be kept.  They can be manually added to this set with
 * `emerge --noreplace <atom>`.  Packages that are listed in
 * package.provided (see portage(5)) will be removed by
 * depclean, even if they are part of the world set.
 *
 * As a safety measure, depclean will not remove any packages
 * unless *all* required dependencies have been resolved.  As a
 * consequence of this, it often becomes necessary to run
 * `emerge --update --newuse --deep @world` prior to depclean.

Calculating dependencies... done!
 * Dependencies could not be completely resolved due to
 * the following required packages not being installed:

 * for more information about --with-bdeps.
 *
 * Also, note that it may be necessary to manually uninstall
 * packages that no longer exist in the repository, since it may not
 * be possible to satisfy their dependencies.


How do I fix this problem?
Thanks.

Did you do a complete update first? (I'd expect a complete update to pull in dev-lang/perl-5.40 - your output indicates 5.38)
Code:
* Have you forgotten to do a complete update prior to depclean? The
 * most comprehensive command for this purpose is as follows:
 *
 *   emerge --update --newuse --deep --with-bdeps=y @world
 *
 * Note that the --with-bdeps=y option is not required in many
 * situations. Refer to the emerge manual page (run `man emerge`)
 * for more information about --with-bdeps.

What's the output of that command?

I ran emerge --sync && emerge -avuDN world yesterday, and it finished successfully, and then I ran emerge --depclean (without performing syncronozation).
Now emerge --ask --update --newuse --deep --with-bdeps=y @world says that a lot of packages will be installed. Why these packages wasn't installed on previuos "emerge -avuDN world"?
OK, will see if it fix the problem

-avuDN is short for --ask --verbose --update --deep --newuse, so the new command is explicitly enabling --with-bdeps=y, whereas the one you used before left it to the Portage default. Per man emerge:
man emerge:
       --with-bdeps < y | n >
              In dependency calculations, pull in build time dependencies that
              are not strictly required. This option is automatically  enabled
              for  installation  actions,  meaning they will be installed, and
              defaults to "y" for the --depclean action, meaning they will not
              be removed. In order to prevent the --with-bdeps option from be‐
              ing automatically  enabled  for  installation  actions,  specify
              --with-bdeps-auto=n  in  either  the  command line or EMERGE_DE‐
              FAULT_OPTS.
Is this implicitly enabled for you? If not, that would explain the difference.

Yeah, --with-bdeps pulled another 47 packages in, and now emerge --depclean finishes successfully.
Thanks guys!

Did you use the binhost? Do you have something in your EMERGE_DEFAULT_OPTS?

Binary packages don't need build dependencies (bdeps). That's the likely reason for the issue. This might actually be worth a bug.

@logrusx I'm not sure about that bug report. One can always do emerge -c --with-bdeps=n, so that emerge does not take BDEPEND into account at all when calculating depcean.

Not relate to this thread topic.

But i just need to confirm my understand for emerge -c --with-bdeps=n Does it mean the emerge -c will actually remove those in BDEPEND?

As I understand it, emerge --depclean --with-bdeps=n will cause emerge not to add packages from BDEPEND into the list of required dependencies. If BDEPEND is the only reason the package is required on the system, then that will allow --depclean to remove the package. If some other package lists the candidate in RDEPEND, then that listing will force the package to remain.

Small addition: Please do not run this without the “-p” parameter ... because you don't really want to uninstall these packages:
Code:
dev-build/ninja
sys-devel/clang
dev-lang/rust
dev-build/cmake
net-libs/nodejs
dev-util/glib-utils
...

:lol:

I don't think the system should get into inconsistent state after use of binary packages. At least my system did never get into an inconsistent state.

EDIT: ops, It just got there:

Code:
