35 matches. Yes I run lxde and many qt codes.

Perhaps better these are currenly blocked (will not update) qt:

Not staying up with the very latest qt packages, causes even more 
problems. I usually have to wait, up to 7 days, as the others trickle in 
and the all the qt packages will install. Sometime I have to remove them 
all, then do the upgrade.

This is the first time it has affected pdf files.

Palemoon will not even load pdfs, at least this version::

NewMoon: 28.9.3  (the unofficial build of PaleMoon.)

I'll guess I just wait a few days and see what trickles in on qqt upgrades:

That's not output from the above command (dev-python wouldn't be  
there.)  Please show the output of the above eix command, or perhaps  
try "eix-installed -a | grep dev-qt" for another look to be sure all  
are at the same version.

What is trying to pull in qtcore-5.15.0?  You started this with a  
problem of pdf viewers all complaining about mismatched qt versions,  
but this looks like a portage issue.  If you are manually marking  
dev-qt packages as ~, you have to be sure you have gotten them all.   
All dev-qt packages (some, such as qt-creator are on a different number  
scheme) must have the same version.  They are generally released all at  
the same time, so incomplete upgrades are likely due to a problem in  
package.accepted_keywords.

Correct.

Yes, OK, but I cannot tell which ones are not unmasked from the output

The formats even look different.  Is the above a trimmed version of what

They all look like 5.14.2, so I think we're still mixing two different 
problems.  Your original PDF error output suggests mixed qt versions, 
but I don't see that in the above.  If you're trying to update all qt to 
the next version, read on.

I'm no longer sure which output you are talking about, but I would try 
doing "eix-installed -a | grep dev-qt" and then be sure you have 
unamsked the 5.15.0 version for every one currently at 5.14.2.  I would 
also check if there are updated versions or any dev-qt package which 
does not use the 5.14.2/5.15.0 numbering scheme.

Then, if the emerge doesn't work, post the exact command you used, and 
the full emerge output.  Attempting to trim it generally ends up cutting 
out some important or useful lines.

For a much easier to parse (and more email friendly) output, try

qlist -ICv dev-qt/

Those are the installed. It's trying to upgrade to the latest:

It's trying now to downgrade  any to 5.13.2, or 5.14.1  etc.

I'd rather just block them for now until the 5.14.2 stabilizes?

Any quick (syntax) suggestions on locking into the newest offerings for 
qt* would be keen, as what I have tried, to date, does not seem to 
placate the qt_beast.....

Since purging python 2.7 pathway is underhand (not complaining) I 
figured I might as well be up on the latest qt*, as the newest codes 
always seem to work for me.  My next gentoo install will be all 
testing/edge codes.

Note: I also use a wide variety of secondary sources for ebuilds, for 
example:
sync-uri = rsync://roverlay.dev.gentoo.org/roverlay

I suspect the problem(s), that are recurring upgrades with qt* may be do 
to the latest release of qt packages, these extra repos, or something 
unknown to me  as a necessary sequence to upgrade qt packages. It is a 
recurring problem.

Most of your Qt packages have the 5.14.2 version, except dev-qt/qtquickcontrols and dev-qt/qtsvg which are still at 5.14.1. Please try upgrading them:

# emerge -av1 =dev-qt/qtquickcontrols-5.14.2 =dev-qt/qtsvg-5.14.2

I to have quite a few qt packages.  I sync once a week so maybe this
makes some difference. However, when I see one upgrade, they all upgrade
at the same time. I have around 30 packages installed here and they tend
to all update together.  Do you have some setting somewhere that is
blocking some of the updates?  USE flag maybe?  One thing I've noticed,
if you add one to use unstable packages, you have to do them all.  It's
either all of them or none.  I don't think I've ever seen a time where
one can be out of sync with the others. 

It may help if you would post the errors you are getting and the
commands you are running to get them.  It's pretty much impossible to
help when we don't know what is failing and why.  Error messages help to
figure out what is failing.

Please try with:

# emerge -av1 $(eix --category dev-qt --installed --only-names)

You may also try adding the -n (--noreplace) emerge option if you want.

Yea, the QT issues, happen every time the bleeding edge (of qt) 
releases. Once I get the packages all upgraded, the bleeding edge qt 
stuff works great (thanks to all the gentooers that work on qt!).....

After thumping all teh cups codes, it works again, but some office files 
from a pc that were originated in europe, cause the print to hickup. The 
hp printer complained about version 1.... version 2 on the tiny hp 
display. Rebooted several times and all my linux printing started 
working again. I have the original hp firmware (10 years old). I do not 
trust the updated hp firmwares, for several reason....

H.P.\ software is just horrible in general.  They are one of  "those"  companies
that treat Linux users as second-class citizens.  The ppd files they  distribute
are full of bugs; I remember spending multiple weeks fixing the description file
for their then-newest home printer, and I still never got  the  scanner  working
(their own software segfaulted, and customer support told me to download Windows
as a fix).  After a while, I gave up and bought a Lexmark B2442  laser  printer,
since I only ever print text documents.  It has never  given  me  any  problems.
The `ppd` files work out  of  the  box.   Coming  from  H.P.,  it  is  a  lovely
experience.

You're not using bleeding edge Qt, 5.14.2 is from the stable tree. 5.15.0
hit testing last week.

[gentoo-user] printing pdfs

[james]

comrades,

Pdfs are becoming a challenge to print. I'm sure I'll be printing pdf 
files for decades to come.

So what application/strategy gets me past errors like this:

"Cannot mix incompatible Qt library (version 0x50e01) with this library 
(version 0x50e02)"


Not being able to print pdf files is simply a no-go for me. I have no 
intention of converting 10K+ pdf files to another format...

Suggestions are most welcome, as what I have google-read, it's a mess 
and I'm no closer to a gentoo centric solution.

Which application are you printing from?
I guess it's a Qt application. In that case, please verify that all packages in the dev-qt category on your system have the same version number.

You can use eix, for example:

$ eix --category dev-qt --installed --compact

You should probably start with letting us know what
application/strategy gives you that kind of error.

I use Okular myself.  I don't recall it ever giving me a error.  It
opens fine as long as the file isn't corrupt or something.  Unless you
have it installed already, you may not want LOo installed.  It is a bit
large for opening and printing a pdf file.  Overkill would be putting it
lightly.  LOL  If you have it installed already tho, I think it opens
and prints pdf files. 

To the point someone else mentioned.  If you have a program that uses qt
and all qt packages aren't at the right version, usually the same
numbering, you will get errors.  I've ran into that in the past with
several programs.  Some qt package fails to compile during a update and
some are the new version and some are the old.  When I try to start a
program that uses qt, it pukes a error on my keyboard about the
mismatch.  That's the only way I've ever seen that error tho.  Once I
get all the qt packages to the same version, then things work like it
should.  I might add, some KDE packages do that as well.  I'm sure there
are other packages that have to be updated together to work correctly as
well. 

First, tell us what you are using and what generates the error.  Second,
make sure all the qt packages are at the same version.  If needed, a
screenshot of the error is better than nothing.

You simply started something compiled with an older Qt lib.
After some updates wether restart your desktop or pc if this dies not help...

How is your printer connected ?  If it's using  The  Common  Unix  Print  System
(C.U.P.S.) as many do, try the lpr command (from `net-print/cups`).  The  server
on which C.U.P.S.\ is running is specified with the `-H <address>` argument, and
various options can be specified with `-o <key=value>`.

To take the example from the man page of lpr:

        Print a double-sided legal document to a printer called "foo":
        $ lpr -P foo -o media=legal -o sides=two-sided-long-edge filename

If your printer is remote, as mine is (on a server called `genserv`), you can do
the following:

        $ lpr -H genserv -o sides=two-sided-long-edge paper.pdf

This is not a suggestion that you abandon the issue  of  mismatched  Qt  library
versions, but rather a simple workaround to use while the  various  Qt  programs
get up-to-date with the latest versions of the libraries. Providing C.U.P.S.\ is
configured correctly with all the appropriate `ppd` files  for  your  particular
printer model, lpr should work out-of-the-box.
