py3cairo build fails 14.1 multilib
 

Hi folks, this problem has been nagging me for a while and I have been searching over the last week to find a solution with no luck. I'm hoping some of the great minds on the forum might be able to teach me what is wrong and how I might be able to figure out similar problems in the future on my own.

I recently attempted to install devedeng as well as virt-manager from slackbuilds.org and both are giving me problems. I have virtualbox installed so I'm really just focused on devedeng for now, but the problem seems to be related to python in both cases.

I am running Slackware 14.1 multilib fully updated as of this posting and all my packages from slackbuilds.org are also updated other than devedeng. Building py3cairo (dependency of devedeng) fails with this "error message" using sbopkg (doesn't really say much):

However when I build the package manually it compiles and I can install it. Even if I do that and then skip building the package with sbopkg I get this error when trying to launch devedeng:

Version: 4.2
Traceback (most recent call last):

gi._glib.GError: /usr/share/devede_ng/wmain.ui: required gtk+ version 3.10, current version is 3.8

Anyone have an idea what might be wrong?

Sorry, this is my fault. I failed test if devedeng ran in 14.1, only that it built fine since it was a chroot I was testing in. Seems 14.1 has an version of gtk+3 that is too old for devedeng... You could build a newer gtk+3 yourself with the current slackbuild/source, but that's not really a solution... I suggested that the old version of devede slackbuild remain on SBo since its a bit different with dependencies, but it was removed anyways. I did save the slackbuild though, maybe it will work better for you.

devede.tar.gz

Perhaps devedeng should be removed from SBo and replaced with the old slackbuild for now and leave devedeng only on Ponce's repo?

orbea, thank you for the quick response, but that link gives me a 403 error, forbidden.

Fixed....

Thanks for clarifying orbea. So the only way to build it from source would be to get gtk3.10?

According to your error message devedeng seems to need at least gtk+3.10, 14.1 has gtk+3.8 and current has gtk+3.16 where it does work. Assuming you don't want to run current you could build a newer gtk+3 using Pat's current slackbuild (I'm not sure if that would mean if you need to rebuild anything else or not too?) or you could run the older version of devede which probably still works, but is no longer maintained since the developer jumped to python3.

"gi._glib.GError: /usr/share/devede_ng/wmain.ui: required gtk+ version 3.10, current version is 3.8"

Right, so I guess my real question is would you compile or try to compile gtk 3.10 from source and install say with src2pkg alongside or on top of the current version on my system? Or would that break things and me sad :(

Just tried and after I installed wayland to support a failed ./configure I get these deps :

configure: error: Package requirements (glib-2.0 >= 2.37.5 atk >= 2.7.5 pango >= 1.32.4 cairo >= 1.12.0 cairo-gobject >= 1.12.0 gdk-pixbuf-2.0 >= 2.27.1) were not met:

seems like a big pia :(

I'm gonna try anyway :p

I love trying to break Slackware it's always more of a challenge compared to other OS's and distro's....

If I were to recompile gtk+3 I would grab everything here - http://mirrors.slackware.com/slackwa...ource/l/gtk+3/

Then I would make the make gtk+3.SlackBuild executable, run it just as any SBo slackbuild and install it with upgradepkg so it would replace your current gtk+3. Some packages may link against your old gtk+3 and break, but that can be fixed by just recompiling them just like you did with gtk+3. If that is the case you will have to find that out yourself and if you are not comfortable maintaining your own system I would not recommend it even if its not really all that difficult.

Thanks orbea, I'll give it a shot and report back. :D

I did what you said and now the build fails with the same error and all text in xfce4 and in terminator are rectangular blocks. :(
Don't know what to do now.

Logged into another account that uses Enlightenment. No problems here.

This is too much for me I'm in over my head. Reverted back all the old packages with slackpkg upgrade-all. I didn't actually even need devedeng anymore I was just trying to get it to work for bragging rights I guess :( no luck maybe I'll wait for Slackware 14.2 :p

Either way Slackware is still the best hands down most stable! I know I would have run into major problems trying this on any other distribution. Thank you to all the maintainers and developers for all your hard work as always and thanks to orbea for your quick explanation. I guess I'd better hit the books if I want to take it to the next level.

Any suggestions on how I could learn more about the building process? Maybe I should give LFS a try if I really want to learn any more, been contemplating it for some time now. Anyways marking as solved.

Long Live Slackware!

You could study the slackbuilds.org templates, editing slackbuilds and and making your own is good practice too.
