Tried looking for "gtk+-2.0" online via duckduckgo but sadly found nothing helpful. :(

Thanks beny, that did the trick. :friends:

But I am not 100% happy with the result.
I hacked the C source code to change the maximum slideshow pause from 30 to 99 seconds, and it works as intended.
Image
:)

But the size of the resulting binary is abysmal.

this is the one from viewnior-gtk3-1.7-x86_64-2ncm package / module:

Code: Select all

-rwxr-xr-x 1 root 162528 2021-09-22 14:42 viewnior
and this is the one I just compiled. Main difference is mine is GTK2 but I prefer it since GTK2 applications seem to run more efficient compared to GTL3 ones. And its v1.8 compared to 1.7

But why is it so much larger?

Code: Select all

-rwxr-xr-x 1 root 769384 2023-10-04 00:17 viewnior
More than 4.7 in size.

The problem, there seems to be more than one maintainer of the same program and I choose the branch that seems to be most up-to-date. But what do I know about how that variant is maintained.

These are the directions I followed for compiling from source
https://siyanpanayotov.com/project/view ... ource-code

Anyone any ideas how I can decrease the size of the binary? Aside from its size, it seems to work flawlessly (and of course now supports the pause between images in slideshow from 1 to 99 seconds, where all other versions only supported 1 to 30 seconds.)

And here the diff of the hacked C file:

Code: Select all

root@rava:/tmp# diff vnr-window*
488c488
<     spinner_adj = (GtkAdjustment *) gtk_adjustment_new (window->prefs->slideshow_timeout, 1.0, 99.0, 1.0, 1.0, 0);
---
>     spinner_adj = (GtkAdjustment *) gtk_adjustment_new (window->prefs->slideshow_timeout, 1.0, 30.0, 1.0, 1.0, 0);
As you can see, a most minimal of hacks. :oops:

here's the slackbuild i used for my package..
the version is somewhat arbitrary since it's just pulled from BwackNinja's git fork..
the size difference could be due to the config line: --optimization=2 and/or the standard binary strip of slackbuild further down..
it would be easy enough to adapt this to whatever source you prefer.. and add whatever patches..

Yeah, i should have looked into that.

I used https://github.com/hellosiyan/Viewnior/ ... 1.8.tar.gz as by the link in post #3 above. :D But the C source should not be the issue here. (Hopefully)

BTW, how can I determine why 05-devel won't let me deactivate it?

BTW² - when you both use viewnior, why is there no DE with it included and/or why is there no official viewnior module available? (Or did I once more just not find these?)

ncmprhnsbl I altered the viewnior.slackbuild like so:

Code: Select all

TMP=${TMP:myviewior/RAVA}
PKG=$TMP/package-$PRGNAM
OUTPUT=${OUTPUT:myviewior/}
since I want the downloaded and extracted files on my hard drive, not on my /tmp/ - so that I can patch the vnr-window.c prior the compilation.

But seems I am too stupid to understand the used bash code. I have no clue where the .slackbuild put the downloaded file or extracted the file into.
It should have been ./myviewior/ or ./myviewior/RAVA but there is no such folder as ./myviewior/ ???

well the one difference i see is the missing dash after the colon..

Code: Select all

TMP=${TMP:-myviewior/RAVA}
PKG=$TMP/package-$PRGNAM

but you can simply have:

Code: Select all

PKG=$TMP/package-$PRGNAM
OUTPUT=myviewior/
in my case, the archive downloads to the dir where the slackbuild is, ie. pwd, since that's usually where it should be run from.

:), you answer yourself: "each core is able to handle 2 tasks at once" 4 cores, 8 threads. = 100% of cpu compiling.

Since I am on Porteus 5.0.1 I have to wait until I find its 05-devel. See this post: Porteus-v5.01 bug reports (Post by Rava #96124)
Until then I have to wait. :coffee:

Then I use "if false; then" to skip the download and extract part and go right to this line

but it compiled okay. Smaller than my 1.8 version:
210088 bytes (205.16 KB) - but I wanted it as GTK2 - and I presume that version I just compiled is a GTK3 one.

I will try again using the other source code that previously compiled into the too large executable using the almost same ./viewnior.slackbuild - I will have to tweak it even ore reflecting the other paths of the other source code.

Wish me luck.

But that version I just compiled, the 205.16 KB one, is also able to have a max pause between images of 99 seconds, just as planned. B)
