[SOLVED] Libgtk-3.so.0 missing

Project Discussion
1

Hi All,
I installed a program called XOD in a toolbox with dnf. It installed okay but it won’t start as library libgtk-3.so.0 is missing. I have done every search I can think of in dnf but, while there seem to be a lot of programs that use gtk3, none seem to actually be it.

So I expanded my search and found a .rpm file that looked like it was the right one (from this page RPM resource libgtk-3.so.0), gtk3-3.24.8-1.fc30.i686.rpm. Downloaded and installed okay, but xod still produced the same error. So tried a couple more, gtk3-3.24.10-1.fc30.i686.rpm and gtk3-3.24.11-1.fc30.i686.rpm. Again installed fine but xod still fails.

What do I have to install to get this library?

Thanks, Ian

A plain old sudo dnf install gtk3 should work, did that not do the trick? If not, what does ldd the-app-binary say?

Hi @refi64,
I tried your suggestion, dnf told me package gtk3-3.24.11-1.fc30.i686 was already installed, but xod still complains that libgtk-3.s0.0 cannot be found. Could it be a path problem?
Not sure what the app binary is. To execute the program I enter “xod-client-electron” in the terminal. Is that the binary?
I tried ldd xod-client-electron and it told me it doesn’t exist. So I did a locate of xod-client-electron and found it in my /opt/XOD IDE folder. ldd /opt/XOD IDE/xod-client-electron didn’t work apparently because of the space in the directory name. I put the whole name in brackets and it worked!
It located a number of files that are not found. These are:

libgtk-3.so.0 => not found
libgdk-3.so.0 => not found
libX11-xcb.so.1 => not found
libasound.so.2 => not found

I tried locate libgtk-3.so.0 and there seems to be plenty of them. This is the output

I’m no techhead (in case you hadn’t noticed…) so I’m really confused now. Why can’t the ap find the library? Is it a PATH problem?
:-\ Ian

Edit: I also tried a locate of the other two missing files, and they really are missing. Locate produced no results. :frowning:

Hmm, something just stuck out to me: are the system and program 32-bit or 64-bit? You currently have 32-bit GTK installed, so a 64-bit app won’t find it.

5

That would explain it. As far as I am aware everything is 64 bit. What do I have to do to install the correct libraries?

EDIT: Believe it or not I managed to solve this problem. Created a new toolbox (gotta love toolboxes!) and installed XOD. Then installed GTK3, and NSS, which only left libasount missing. That took a bit more sleuthing, but I eventually learned it is in alsa-lib.x86_64. Installed that, at voila! xod works! Barking frilliant!

Thanks for all your help yet again @refi64, much appreciated.

:slight_smile: Ian

Don’t forget, file names and paths are acceptable arguments to dnf.

dnf install libasound.so.2 and dnf install libgtk-3.so.0 are valid commands.

Thanks @pluto, I did not know that. That makes life MUCH easier!

:wink: Ian

You can do even crazier stuff like

dnf install 'pkgconfig(glib-2.0)' for when you get build errors and don’t want to Google package names

sudo dnf install 'perl(Text::CSV)' pretty self explanatory.

sudo dnf debuginfo-install package fetch debug-symbols, coredumpctl will even tell you what debug packages to get for better dumps.

Okay you’ve lost me now @pluto. I’m just a humble non-techhead end user, I don’t understand the inner workings deep in the bowels of Linux.

Basically, all RPM packages can declare a list of strings they “provide”.

For instance, all Perl packages in Fedora have perl(The::Package::Name) in their Provides list, so you can install a Perl module via dnf install 'perl(Text::CSV)' without actually knowing the full name, or find out what package it is via dnf whatprovides 'perl(Text::CSV)'.

This is also available for installing development libraries: any packages that contain a pkg-config file xyz.pc will have pkgconfig(xyz.pc) in their provides list. Compiling something and it says it can’t find ostree-1.0? Just dnf install 'pkgconfig(ostree-1.0)'.

Every file inside a package is also on its provide list, which is why dnf install /usr/lib64/libsomething.so works: dnf looks through the packages and finds the one that “provides” that file.
