I've done that & everything seems to be ok (big smile).

At first, I didn't notice that revdep-rebuild nees to be run with gcc-5.4.0 :
since r-r is written in Python, the version of Gcc seems irrelevant.

After noticing that, there was no problem.  r-r announced no problems.
I tested the new Gcc by finishing updating KDE (which I had started)
& everything went thro' efficiently & a bit faster, if I'm not mistaken.

Thanks as always to the Gentoo devs, who rarely make mistakes
& provide us users with the best distro for serious desktop work ;
also, no doubt, to the people who are working hard improving Gcc.

[gentoo-user] How to get rid of sys-fs/static-dev, or do I really need it?

[wabe]

Hi folks,

tried to do an "emerge -eav world" but it didn't even start, because of:

INFO: pretend
Package:sys-fs/static-dev-0.1
Repository: gentoo
Maintainer: base-sys...@gentoo.org
USE:abi_x86_64 amd64 elibc_glibc kernel_linux userland_GNU
FEATURES:   ccache preserve-libs sandbox userpriv usersandbox
ERROR: pretend
We have detected that you currently use udev or devfs or devtmpfs
and this ebuild cannot install to the same mount-point.
ERROR: sys-fs/static-dev-0.1::gentoo failed (pretend phase):

Call stack:

  static-dev-0.1.ebuild, line  22:  Called die
The specific snippet of code:
die "Cannot install on udev/devfs tmpfs."



I'm using sys-fs/eudev and no static /dev. So I tried to deplcean 
sys-fs/static-dev but this failed because of:

!!! 'sys-fs/static-dev' (virtual/dev-manager) is part of your system profile.
!!! Unmerging it may be damaging to your system.


What can I do to solve this problem? Is it safe when I just unmerge 
sys-fs/static-dev?

I think mostly they will be sending some pdf files + some images.
After sending the encrypted file they will follow with a call to provide
"password" this shouldn't be a problem.

I'll try 7zip, see if it works already.

If they are Win10 users you also have them install the windows subsystem
for linux, then you will have GNUPG already installed. The one thing you
need to know is that the ~/ in bash is not the windows home directory.
You will need to cd to /mnt/c/Users/.

7zip can create AES256 encrypted archives, and the majority of Windows
"power users" will have it installed already.

Unfortunately if you want asymmetric encryption there is not much else
besides GnuPG. Gpg4Win offers a GUI and might be more friendly. There
is also the Enigmail plugin for Mozilla Thunderbird.

As strange as this might sound, you should also consider telling your
recipient to install Cygwin and GnuPG, as often times (at least in my
experience) the main problem with using GPG on Windows is buggy
wrapper layers. If it is used directly there are next to no issues.
Should your recipients be at all inclined the necessary commands can
be remembered easily and don't need much modification.

What is it you want to encrypt?  An email?  An attachment?  Both?

For email inc. attachments you can use SSL Certificates with S/MIME.  MS 
Outlook can handle S/MIME encrypted emails natively and you can get SSL 
Certificates from a variety of CAs, some of them free for personal use.  You 
can always use self-signed certificates, but initially you will have to guide 
your recipients to store the self-signed certificates and mark them as trusted 
on their PCs.

Alternatively, you can install gpg4Win on MS PCs and use that to exchange PGP 
encrypted messages and attachments.  Your recipients may need some training to 
familiarize themselves with the gpg4Win interface, but it is not that 
dissimilar to MS Outlook's S/MIME GUI.

Thunderbird can deal with both PGP & S/MIME using Enigmail.

If you only need to encrypt attachments (files/directories) besides the above 
solutions (gpg4win will also encrypt/decrypt files separately to emails), you 
can use zip/7zip and encrypt with a symmetric key the contents of the 
generated archive.  You will need of course to share the encryption password 
for the zipped archive with your recipients securely off line.

PS. 7z can create self-extracting archives and I had looked into this in the 
past, but I was not able to make it work off the peg in Gentoo.  It kept 
asking about /usr/lib64/p7zip/7z.sfx which is not installed by default with 
7zip.  After some failed attempts I gave up and sought alternatives.

[gentoo-user] encrypting file for Windows users

[thelma]

I'm looking for a solution to encrypt and attachment to Windows users.
gpg does not support "sda" Self Decrypting Archives.

Occasionally I have to send an attachment via email and would prefer if
the file was encrypted.  Asking Windows users to use PGP is almost
impossible.
Sending them txt.exe and asking the to run it will not go well.

PS. Note that I did immediately switch to the new compiler. 

I dont know how well "having the new gcc around but not using it" works, since 
its standard libraries are not affected by the gcc-config mechanism (and thus 
a gcc-4.* will happily use the libraries installed by gcc-5). 

If you want to keep your system gcc-4 only (which is only going to work for a 
very limited time), you should locally mask the newer versions. Offhand I see 
no real reason to do that though. As somebody said, "2014 called - it wants 
its compiler back!"

My personal advice & experience:
* install the new gcc-5.4
* switch to it
* run the revdep-rebuild command from the news item (see above)
... and everything should be fine.

To be absolutely sure I've run an "emerge -eav world" on most machines 
sometime afterwards, but that shouldnt be strictly necessary. (It helps though 
if the revdep-rebuild command doesnt finish for some reasons.)

Somehow the 5.4 stabilization got stuck and/or forgotten, it's been overdue 
for a while now. Many devs (including me) use 6.3 on their main machine 
already, without any too big problems. gcc-6 is already used by the big binary 
distros. (-> Expect 6.3 to get keywords sometime soon.)

While it does read like that, I would think that it's safer to just do the 
revdep-rebuild.

I followed the instructions and everything went fine, albeit it took about 2 
days on my desktop just for the revdep-rebuild.  I had a few build failures, 
but almost all of them were from packages in the proaudio and my personal 
overlay.  The only package from the main Gentoo tree that failed was 
libsidplay, but that was due to a bash/dash compatibility problem that causes 
the configure step to produce broken Makefiles.  *double checks* No, sorry, on 
my desktop the following also failed to build:
- games-emulation/nestopia, 
- games-emulation/mupen64plus,
- media-sound/ams
- media-sound/seq24,

For the first two, I wouldn't be surprised if their ~arch versions work.  The 
latter two are probably unmaintained upstream and need to be patched.

Thanks. This worked.

I have been using the kde/plasma version for kmail for a while. After the 
gcc5.4 upgrade, I wanted to rebuild everything and encountered this issue.

I'll need to read up on the profile directory options.

First, there is no package.use.unmask (although I'll grant that that would be 
the intuitive name for such a file).  There is only package.use.mask and 
package.use.stable.mask, which can reside in the portage tree and in /etc/
portage/profile/.  portage(5) has this to say (see especially the second 
example):

package.use.mask and package.use.stable.mask
 Per-package USE flag masks.

 Note: In a cascading profile setup, you can remove USE 
flags in children profiles which were added by parent profiles by prefixing 
the flag with a '-'.

 Format:
 - comments begin with # (no inline comments)
 - one DEPEND atom per line with space-delimited USE flags

 Example:
 # mask docs for GTK 2.x
 =x11-libs/gtk+-2* doc
 # unmask mysql support for QT
 x11-libs/qt -mysql

In this particular case, both files can be used, it seems (I'm not sure what 
the "stable" refers to in this case, it's probably explained on the Gentoo 
wiki somewhere or in the developer documentation).

I'm currently rebuilding 304 packages. However, last time I updated
major versions of gcc I had weird issues, an `emerge -e world` fixed
that. Some packages have already been built with the new gcc version, so
I plan to exclude those from --emptytree.
