Rava, try again, I think I fixed it, mega's fault

Ideed now it works. mega seems to be … "moody" at times.

I used lsxzmgrep V2020-12-19 (the script is to be found somewhere on this forum, it's by yours truly adapted from lsxzm) to look into older versions of rc3 - to no prevail, not one single base/ contains libpoppler-qt5.

I used libpoppler-qt5-1_21.06.1-1_amd64.deb to create libpoppler-qt5-1_21.06.1-1_x86-64.xzm (by moving the lib into /usr/lib64/ from the wrong-for-slackware folder the .deb uses)

Result after activating:

Code: Select all

guest@porteus:~$ ldd /usr/bin/texstudio|grep found|sort
	libpoppler.so.111 => not found

So I did a (more or less dirty) symlink hack:

Code: Select all

root@porteus:/usr/lib64# ln -s libpoppler.so.105.0.0 libpoppler.so.111
root@porteus:/usr/lib64# ls -o libpoppler.so*
lrwxrwxrwx 1 root      17 Nov 14 04:52 libpoppler.so -> libpoppler.so.105
lrwxrwxrwx 1 root      21 Nov 14 04:52 libpoppler.so.105 -> libpoppler.so.105.0.0
-rwxr-xr-x 1 root 3584240 Dec  7  2020 libpoppler.so.105.0.0
lrwxrwxrwx 1 root      21 Nov 22 14:53 libpoppler.so.111 -> libpoppler.so.105.0.0

Result:

Code: Select all

guest@porteus:~$ texstudio 
texstudio: symbol lookup error: /usr/lib64/libpoppler-qt5.so.1: undefined symbol: _ZN6Stream12discardCharsEj

Seems I suck at this.

[beny]

hi maybe this is useful:http://alien.slackbook.org/slackware/sl ... 4/current/ take a look if work for you

[rych]

Rava, patience, I'll upload all of my modules tomorrow including poppler. In the meantime you could start installing TexLive, if you haven't already, and I recommend a portable installation to an ext4 Linux partition because it can grow large above 1GB and it tends to update frequently, so doesn't suit for a module+changes paradigm (just as Firefox for example) -- but that's just my opinion, many porteus users don't even have an ext4 partition

[Rava]

many people don't even have an ext4 partition

So do I, just ext3.

Rava, patience, I'll upload all of my modules tomorrow including poppler.

I can wait one day. See you then.

Nope, sadly it does not. Created and activated python-poppler-qt5-21.1.0-x86_64-3alien.xzm.

I first removed the dirty symlink hack aka /usr/lib64/libpoppler.so.111 -> libpoppler.so - then I get the same "libpoppler.so.111 not found"

When I create the link again then I get the same old same old:

Code: Select all

texstudio: symbol lookup error: /usr/lib64/libpoppler-qt5.so.1: undefined symbol: _ZN6Stream12discardCharsEj

For now I'll be simply patient. And wait a mere single day.

hi Rava there is a link to poppler-qt5 always in the alien bob repos but is tagged 2018 a bit too old i think.but just for the record here the link:

thanks beny, appreciated, but I simply wait for rych. He seems to be better at handling dependencies for texstudio.

Off topic example… me and shrinking GIMP module

It took me a while to figure out how to slim down a standard GIMP module… some changes like resizing the startup image do not have negative side effects, removing libraries named essential but that are not really essential did make GIMP complain a lot about stuff, but it opened up okay and all I did with GIMP worked as it should. And I never received any feedback of a certain function not working.
That could still be the case since GIMP is one of the most complex programs in the open and free software world, and even when I do have a large book on GIMP I can hardly be called an expert in using it - I just do not have the time to learn all that would be needed. I only use it on a rare occasion when mtpaint cannot handle a certain detail. Usually mtpaint can do 99.9% of what needs to be done.

Please reply to the off topic part not here but in my most recent x86-64 module thread about GIMP - gimp-2.10.22-x86_64-2 stripped + minimal dependencies for 5.0rc

Rava, My porteus/modules folder is complete now, same link which is also in my Profile signature to the right "Contact: ... <Website>"

My LaTeX stack is TexLive (separate installation), texstudio, qpdfview, LyX -- I grouped them in folders but there is dependencies overlap, and for or instance, qpdfview module includes poppler. I obviously have some other modules there unrelated to latex, e.g. Japanese input etc. It all works for me. Good luck!

I am not sure which module I lack and need.
The folder Texstudio has
hunspell-1.7.0-x86_64-1.xzm
quazip-1.1-x86_64-3.xzm
texstudio-4.0.4-1-x86_64.xzm

All these I have already, also these I have:
qt5-base-5.15.2-x86_64_10-xfce-cinnamon-openbox-lxde-mate.xzm
qt5-dev-5.15.2-x86_64_10-extralib.xzm

Now what is the module that I must still miss for resolving my above mentioned issue?

[beny]

libpoppler-qt5 is included into the poppler slackware current package if you don't have make a package: of poppler
libpoppler-qt5.so.1.30.0

Seems it was cut since many DE not use qt5 (e.g. Openbox and XFCE) so it is neither part of 00[12]-* nor part of my 003-xfce4 module.

Any ideas?
I am not familiar with wayland, and I have no clue about "eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, webgl, xcb" either.

How to resolve such an issue.
The Could not load […] even though it was found is a new one for me.

Rava, As I said, my qpdfview module, which you find at my link above (can you see it?), includes poppler, xcb, etc.

Rava, As I said, my qpdfview module, which you find at my link (can you see it?), includes poppler.

You did, but it should have worked with my poppler as well.

I deactivated my poppler module and activated your qpdfview module instead:

Rava, Maybe something isn't right with your Qt5. Could you try as an experiment to activate and start the small File Manager QtFM module I have there? I'm suggesting this because it relies on xcb libs too viewtopic.php?f=74&t=8286

Should I try using ncmprhnsbl modules from QtFM for OpenBox (Post by ncmprhnsbl #81385) when they exist instead of the ones by you as an initial test?

Added in 9 minutes 43 seconds:
Update
I downloaded his other 4 modules as well and activated these. The error remains the same.

Maybe I do have some QT based program unknowingly activated that uses some outdated stuff? Could that be the reason?
Maybe I should reboot and deacivate all my extra modules - which means no browser and no email (palemoon and interlink respectively) and no ebook reader (fbreader) . So no writing a reply here but I could test the QT issue.
